How to install gcc-4.2 - ruby-on-rails

I am trying to update ruby and rails on my system (osx 10.8.2)
When I run
rvm install 1.9.3 --with-gcc=gcc-4.2
I get the following error:
You requested building with 'gcc-4.2' but it is not in your path.
2 questions; how do I install using gcc-4.2 (I have installed command line tools in xcode)?
Also, How do I get it to the correct path?
Any help in this issue would be greatly appreciated.

If you're not using Homebrew already, you'll probably want to install it, along with the apple-gcc42 package. This script will do that for you, but you'll probably just want to manually run the parts of it that you want: https://github.com/thoughtbot/laptop/blob/master/mac

Try installing using this package: https://github.com/kennethreitz/osx-gcc-installer

Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib

When I try running rails console I get this error:
/Users/TuzsNewMacBook/.rvm/gems/ruby-2.3.7/gems/bootsnap-1.3.2/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:21:in `require':
dlopen(/Users/TuzsNewMacBook/.rvm/rubies/ruby-2.3.7/lib/ruby/2.3.0/x86_64-darwin18/readline.bundle, 9):
Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib (LoadError)
A quick search got me to this post and I've tried a few things:
brew reinstall postgresql (this is indeed the DB for this project)
and
cd /usr/local/opt/readline/lib
ln libreadline.8.0.dylib libreadline.6.2.dylib
(my version of readline is 8)
and
brew link readline --force
But none of these have fixed it.
I recently added pry-coolline, guard and guard-livereload gems to my project if that makes any difference (rails console loaded fine before those). I'm running on the latest macos.
(Update) I’m using pry rails as my rails console, if that makes any difference.
Any help? Thanks.
the error seems to be thrown when searching for /usr/local/opt/readline/lib/libreadline.7.dylib.
Have you tried to symlink that?
So something like:
cd /usr/local/opt/readline/lib
ln -s libreadline.8.0.dylib libreadline.7.dylib
Just tried that on macOS Mojave, ruby 2.5.3p105 and Rails 5.2.2 and worked.
Reinstalling my Ruby version seems to have fixed it:
rvm reinstall 2.3.7
can you try
cd /usr/local/opt/readline/lib
ln -s libreadline.8.dylib libreadline.7.dylib
you are on the right track but it seems like rails is looking for libreadline.7.dylib and libreadline.7.dylib is not there in the folder.
Yes, the best answer is to reinstall.
You can get the version easily by typing:
ruby -v
With rbenv, the command is i.e.:
rbenv install 2.3.7
with rvm:
rvm reinstall 2.3.7
A very simple solution that doesn't involve rebuilding your RVM gemset OR sym-linking libraries.
Add to your Gemfile:
gem 'rb-readline'
If you are doing bundler groups
group :development do
gem 'rb-readline'
end
Then run
> bundle
Let me know if that doesn't work.
Most often in Ruby-applications, this is caused by gems that have extensions (the gems saying "Building native extensions.."), that are built using a specific version of, in this case, readline.
Basically, there are two solutions:
Either, you can symlink version 8 of the gem, to the version missing. This will work in many cases, but if backwards compatibility is broken, it will not.
Or, if the gem actually supports version 8, you can reinstall that specific gem, or "pristine" it by running gem pristine --all.
EDIT: In scope of your "what I've tried", reinstalling PostgreSQL, is also one of the binaries, built using a specific version, that may also require a rebuild, to work with a system library, such as readline.
Got this issue:
dyld: Library not loaded: /usr/local/opt/mpfr/lib/libmpfr.4.dylib
doing...
cd /usr/local/opt/mpfr/lib/
ln -s libmpfr.dylib libmpfr.4.dylib
did the trick for me for macOS Catalina
Background: This has happened when I tried to install tig, but I think this is a common issue that you may have that you need to manually link the installed software into the right path that another software wants.
If you can not find readline installed on your Mac, you should run
brew install readline
After you installed deadline, brew will ask you to link it. But actually you can not link by running
brew link readline
Even you can not link by running
sudo brew link readline
Mac OS will warn you this is extremely dangerous and stop you to do.
The Latest version of readline is version 8, so you will see the error message like
Library not loaded: /usr/local/opt/readline/lib/libreadline.8.dylib
The brew installed deadline at
/usr/local/Cellar/readline/8.0.4
So you have to manually link it to the place that your software wants by using command ls
ln -s /usr/local/Cellar/readline/8.0.4 /usr/local/opt/readline
Enjoy!
So Ive checked a few answers here but I dont think they can work with a vanilla Mojave mac install. Im using 10.14.4 while I did these:
get homebrew from https://brew.sh
$ brew install coreutils : this installs the gnu coreutils pkg for mac, we want the greadlink from this because macOSX's readlink is not the same as the gnu readlink. Its extremely confusing but such is the life in macland.
$ echo 'alias readlink=greadlink' >> ~/.bash_aliases I found macs readlink to be a bit lacking so I overrode the existing readlink by aliasing greadlink. (you can make this usable by all users by $ alias readlink=greadlink >> /etc/bashrc which will enable every user to be able to use it.
$ ln -s /usr/local/opt/readline/lib/libreadline.8.dylib /usr/local/opt/readline/lib/libreadline.7.dylib I linked the already linked .8. file instead of '.8.0.' file because if it were to get updated to .8.1. then my readlink wont break or miss features on the library. Im pretty sure we will format our macs before 9+ comes out.
I would recommend against manually symlink'ing native libraries. Aas of OS X 10.4, the standard include library path /usr/include is no longer used and is locked by SIP (making it difficult to move things to).
Apple ships a “legacy installer” for you to be able to install the headers in the “old location”, which will also resolve your path to correctly find headers installed via brew.
cp /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg ~/Desktop && open ~/Desktop/macOS_SDK_headers_for_macOS_10.14.pkg`
See here for a detailed write-up on what is going on.
My problem was just the same when running lftp.
Just running brew upgrade has solved my problem, as it has updated (among others):
readline 8.0.0_1 -> 8.0.1
lftp 4.8.4 -> 4.8.4_2

RVM Requiremets tries to tap deprecated homebrew/versions

I'm trying to get a Ruby on Rails project running on my Mac OS Sierra (10.13.3) machine. When I navigate to the Rails folder, RVM tells me the following:
Required ruby-1.9.3-p392 is not installed.
To install do: 'rvm install "ruby-1.9.3-p392"'
However, when I do that install, I get the following:
$ rvm install "ruby-1.9.3-p392"
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.13/x86_64/ruby-1.9.3-p392.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

So. RVM seems to be stuck on this idea of installing homebrew/versions, which has been completely removed by Homebrew. I've updated Homebrew. I've updated RVM. I've tried to trick Homebrew into having that tap available (not successful). I've tried to trick RVM into thinking that's not a required custom package (couldn't figure out how). Nothing seems to be working. Help!
EDIT
I got around the problem by actually upgrading the project to use ruby-2.1.0 . Worked like a charm, but of course didn't actually resolve the original issue. Thank you for the answers below, and hopefully they'll help out some other poor soul in the same situation!
I tripped up on this as well. While it's not a final answer with the help of a kind soul on Github I was able to find a temporary solution to this issue.
If you are running macOS 10.10 or later then you should run brew install gcc49. This will help RVM as it now won't try to tap the deprecated homebrew versions repository. If you are on an earlier version have a look at this function in RVM for the appropriate version of gcc to install.
I have documented the issue I was encountering over here:
https://github.com/rvm/rvm/issues/4303
Had the same problem. This happens only when installing a ruby version older than 2.0. I was able to get past this using rvm autolibs read-only then install the ruby again. This will tell rvm to use existing dependencies and to skip the error if something is missing. Just then try to manually install all the required packages using Brew.
https://rvm.io/rvm/autolibs
I had the same problem when I tried to install Ruby 3.0 . For me just updating RVM to the latest version fixed the issue:
rvm get stable

Rails initialization checksum error

I'm trying to initialize a new rails app on windows, and running rails new <appname> generates everything up to vendor/assets/stylesheets/.keep, but when bundle install is run, rails generates this error:
Checksum of /versions does not match the checksum provided by server! Something is wrong.
I'm not sure what's causing this, as I've done nothing to rails itself. Any help is appreciated.
Edit: If it's an error caused by windows being finicky, I have the option of moving to Linux, but I'd like to know what's wrong first.
I had the same issue using windows, and was able to solve it by uninstalling bundler and installing an older version.
rails new <appname>
gem uninstall bundler
gem install bundler -v 1.9
cd <appname>
bundle install
That did it for me!
In my case there was a *.pre.1 version and I chose to uninstall that particular version and then "bundle install" worked.
Try removing your ruby cache folder and then try again. So for example if you are on Linux machine and you are using rbenv and say ruby 2.1.5 folder. Your path would be similar to something like (Not sure where on windows ruby is stored):
~/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/cache/
Removing this folder and trying bundle install again should resolve the issue.
It will be great, if you move to a Linux machine.
On windows it's a hell to pay in my 5 years of experience what i have learned is not to mess with (ror) or (rs) in windows. here's a cheeky thing you can do an easy way. I believe you are using github as repo, as a editor you are using sublime if thats is a case open your gemfile you will see check the image or
try to clear cache on your server or update the gems.
I had this same exact error and solved it the following way. I think you are missing the ruby DevKit being installed.
Go here http://rubyinstaller.org/downloads/ and download/install the latest 32-bit Ruby version (as of writing this 2.2.4, you will need it for the web-console gem)
Make sure to add your ruby\bin folder to your environmental path variable
The trick is hidden near the bottom-left of the same page under the "Development Kit" section. You need to download and extract the right one into a permanent location (as of writing this for 32-bit - DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe)
After extracting the files, go into the main directory and run "ruby dk.rb init" followed by "ruby dk.rb install" (More information can be found here
That fixed it for me and i can now fully install with no checksum issues
This problem began when i tried to run my app. I wrote rails s and the console said me Could not find sdoc-0.4.1 in any of the sources Run bundle install to install missing gems. Then i wrote bundle install and the message that appeared was Checksum of /versions does not match the checksum provided by server! Something is wrong.
I solve this problem following this steps:
Wrote bundle install
The console said me Could not find sdoc-0.4.1 in any of the sources
Then i reinstalled this gem with gem install sdoc -v 0.4.1
I tried again to write rails s and it's was solved.

Getting a "bad interpreter" error when using brew

I'm getting this error when I try to run any brew command.
Holger-Sindbaeks-MacBook-Air:~ holgersindbaek$ brew help
-bash: /usr/local/bin/brew: /usr/bin/ruby: bad interpreter: No such file or directory
I have absolutely no idea on how to fix this and been searching for a long time without answer.
I got this error (much the same):
/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 26: /usr/local/Library/brew.rb: Undefined error: 0
and fixed by the solution below:
Open brew.rb:
$ sudo vim /usr/local/Library/brew.rb
Change the first line's 1.8 to Current:
Before:
#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -W0
After:
#!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0
Then brew works for me. Hope it helps if any other one got this issue. :)
If you get the error
Homebrew requires Leopard or higher. For Tiger support, see:
https://github.com/mistydemeo/tigerbrew
change the MACOS check from <10.5 to <10.
Tip by #TimCastelijns:
10.5 doesn't work because in comparison, it's higher than 10.10 (.1 vs .5). I added a check (and MACOS_VERSION != 10.10) instead of lowering from 10.5 to 10.
What you are getting means that Homebrew has not been able to locate the Ruby interpretter at the specified location.
Install Apple Developer Kit (comes with Xcode) which should be available to you as an optional install (or you can simply download it from Apple). This will install the Ruby interpreter for you.
In case you already have Xcode installed, this means that one of these things is happening:
You have a broken Ruby installation
You have more than one Ruby installation
Your installation has not been configured properly.
To identify if this is the first case, you can run ruby and see if you get any response.
If you don't, your installation is broken and you need to reinstall it. If you do, you then run which ruby. This should give you the absolute path to your Ruby executable. If this is anything other than /usr/bin/ruby then homebrew (and a bunch of other programs) will not be able to find it.
In case you have not ever tampered with your Ruby installation, you can check to see if /usr/bin/ruby already exists or not: cat /usr/bin/ruby. If you get No such file or directory, then you can easily create a symbolic link to your Ruby installation. Assuming the output of which ruby to by /usr/local/bin/ruby, you create the symbolic link this way: sudo ln -s /usr/local/bin/ruby /usr/bin/ruby and all should be well.
If there is a file at that location, you can run file /usr/bin/ruby to see if it's a real file, a symbolic link, or a corrupted file. If it is a symbolic link, your installation should be working, and since it's not, it probably is either a corrupted symlink or it's a bogus file.
You can remedy that by first deleting it (sudo rm /usr/bin/ruby) and then creating a new symlink to the correct location (sudo ln -s /usr/local/bin/ruby /usr/bin/ruby).
If non of the above works, you should consult the homebrew team after a clean install of Xcode and removing any traces of a Ruby installation on your system.
EDIT
Alternatively, as pointed out by the other answers, the issue might be because of a bad ruby version in your Homebrew settings.
A quick fix might be updating your Homebrew:
cd /usr/local
git pull -q origin refs/heads/master:refs/remotes/origin/master
If this does not help, you might want to get your hands dirty and manually fix the problem by:
Editing brew.rb from /user/local/Library/brew.rb
Changing /1.8/ to /Current/ in the first line, which will cause the hashbang to point to the current Ruby version as the executor
If this does not help, either, you can also modify the MACOS check and change it from 10.5 to 10 to avoid the infamous "Homebrew requires Leopard or higher" error.

A bunch of thanks to other contributors in the answers below and their commenters. I am not committing plagiarism, simply aggregating the answers into one integrated article to help others.
Fix:
sudo gem install cocoapods
At the risk of oversimplifying things, try running
gem install bundler
I was transitioning my Ruby environment from RBENV to RVM and it worked for me.
This happened because I needed to update brew - in the updated version it already uses Current ruby
cd /usr/local
git pull -q origin refs/heads/master:refs/remotes/origin/master
This solved the problem
You need to change the path for Ruby.Framework
I solved it with commands as mentioned.
brew install cocoapods --build-from-source
brew link --overwrite cocoapods
If you have a lower version below Xcode 11, you have to remove it before you use the above commands.
Reference: Ruby Framework issue
None of the above worked for me, so I kept browsing and found this answer,
https://stackoverflow.com/a/24225960/1359088
which did fix brew for me. He says in step 1 to install XCode 6 command line tools, but doesn't say how; use this command:
xcode-select --install
I got the same issue when updated to MacOSX High Sierra & using Xcode 9 with that. High Sierra update ruby gem to version 2.3 but xcpreety command of Xcode 9 still using Ruby 2.0 which is unable to find now & gives bad interpreter.
Just go to Terminal & run
sudo gem install xcpretty
Restart Xcode & do fresh clean build it works for me.
Hope it helps!!!
After upgrading to macOS High Sierra, get it fixed with following commands:
sudo gem install cocoapods
In my case seems like fastlane installed incorrectly with brew install fastlane system didn't write correct path to fastlane. I fixed it with alias fastlane=~/.fastlane/bin/fastlane
I solved it with commands as mentioned.
1.) Uninstall your GEM.
gem unistall GEM
2.) Then Install your GEM.
sudo gem install GEM -n /usr/local/bin
I got bad interpreter: No such file or directory error when used xcpretty and xcpretty-travis-formatter on upgraded MacOS.
To solve it
gem install xcpretty
gem install xcpretty-travis-formatter
That is why I can recommend you to reinstall failed component gem install <name>
#For example error looks like
/usr/local/bin/xcpretty-travis-formatter: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
#use
gem install xcpretty-travis-formatter

Ruby on Rails: no such file to load -- openssl on RedHat Linux Enterprise

I am trying to do 'rake db:migrate' and getting the error message 'no such file to load -- openssl'. Both 'openssl' and 'openssl-devel' packages are installed. Others on Debian or Ubuntu seem to be able to get rid of this by installing 'libopenssl-ruby', which is not available for RedHat. Has anybody run into this and have a solution for it?
I had this problem on Ubuntu, after upgrading to 8.10.
The solution for Ubuntu was
sudo apt-get install libopenssl-ruby
it seems you need to make the ruby header file
go into the openssl directory and:
ruby extconf.rb
cd ../..
make
make install
See here
If you are using RVM to manage your rubies follow the directions here:
http://rvm.io/packages/openssl/
There is probably a gem you are missing. Can you provide the stack trace and the line of code where it originates?
Re-run rake with --trace to get the stack trace printed.
EDIT: Also what version of Ruby are you running? openssl.rb is in my 1.8.6 install
I had the same issue. I tried going into the openssl folder and running make etc but it couldnt find the libraries lcrypto. I solved the issue by running ruby 1.9.3-p327.
Hope this helps!
