I have installed rails and ruby with railsinstaller. The problem is, when i run rails command, it gives me: "The system cannot find the path specified."
Tried uninstalling rails and installing it againt, does not help. Ruby commands executes like "ruby -v", "rails -v" doesn`t work.
Have googled,didn`t find solution for windows, that worked.
You need to set your system PATH variable.
To do this go to
My Computer > Properties > Advanced > Environment Variables > System Variables
Click PATH and add the path to Ruby, which will be along the lines of C:\ruby\bin

I'm invoking a ruby script via backticks from within a Rails controller (and collecting a return integer).
In production, somwhere in this chain, something is insisting on trying to run the ruby script with ruby 2.7.0 (the native system version) and complaining that it should be 2.7.4 (which it should).
The Rails app itself runs fine until I invoke a script.
When invoking the script, Passenger (I think?) is logging in the Apache error.log with
/home/rcm/.rbenv/versions/2.7.4/lib/ruby/2.7.0/bundler/definition.rb:495:in `validate_ruby!':
Your Ruby version is 2.7.0, but your Gemfile specified 2.7.4 (Bundler::RubyVersionMisMatch)
I have searched and tried numerous suggestions (most of which were already done).
All scripts use: #!/usr/bin/env ruby
$PATH includes /home/rcm/.rbenv/shims:/usr/local/sbin:... and the usual suspects (I see that's rather explicit with /home/rcm/.rbenv instead of ~/.rbenv --- does it matter?)
The apache .conf file has: PassengerRuby /home/rcm/.rbenv/versions/2.7.4/bin/ruby
I have .ruby-version files at every layer I can think of specifying 2.7.4
I have used rbenv to declare global 2.7.4.
I have updated bundler.
I have run bundle install.
Restarted apache, rebooted the system, etc.
I can't figure out where in the chain anything could be trying to run the script with 2.7.0.
It all works fine in dev mode on macOS and Ubuntu, and even works fine running the project in e -production mode with the built in Puma on both macOS and Ubuntu. Only in the full Apache > Passenger production mode is there a problem. So, I'm thinking it has to be Passenger that's confused, but it's running the Rails app itself just fine -- which makes me confused.
The screwy part is, this was all working fine, and "all of a sudden" I'm getting this failure. (No idea which bit I twiddled.)
Would appreciate any ideas to give me something new to chase. Thanks.
ruby is not necessarily the same as the ruby running Rails. It will run whatever the first one it finds in its PATH. Since this is running on a webserver, this will be different from the PATH of your own user.
Use bundle exec ruby to run the Ruby associated with the application.
The best thing to do is to not run a script, instead incorporate the script code as a class in your Rails project. This is faster and easier to test.
I installed Ruby and Rails and set-up the PATH to "C:\Rails\Ruby2.3.0\bin", but when I try to run commands with rails, I get the error message:
The System cannot find the path specified.
I am able to run commands using ruby, and rails works if I use GitBash. How do I make it work on my normal command line?
Had the same problem here, installed the same way. Couldn't even run rails commands on GitBash, only way was going in C:\Rails\Ruby2.3.0\binthrough cmd and typing, for example, ruby rails new projectname. The rails new projectnamewouldn't work even in these conditions.
What I did was going in the Command Prompt with Ruby and Rails and entered gem install rails (which did not work on cmd). I also did gem install bundle. Both installed successfully and that fixed all consoles for me: cmd, GitBash (wasn't working for me), Command Prompt with Ruby and Rails and even cmder works with Rails now.
Hope this helps you.
Cheers.
If it's a simple question of locating the rails executable on Windows, then on later installs that use msys64 instead of DevKit, you'll find rails at the following folder:
c:\msys64\o-rdoc
Add this to your PATH or execute from that folder.
Your path may vary on 32-bit systems or if you changed the default install folder.
I have rails 3 installed with rvm and today i tried to add the alias 'subl' (from Sublime Text 2) to use on terminal. The problem is the 'subl' command works and i think i messed up with the paths, because the rails command is not found anymore.
How do I find the correct rails path and fix this problem?
Thanks in advance.
Depends on your setup. If you're using rvm, it will probably be
~/.rvm/gems/<ruby version that you use>/bin/rails
If you're using the system ruby, then have a look in the gems folder of wherever your ruby install is, and add that to the path. On windows, the ruby installer generally puts it in
C:\Ruby
Or something like that. On Mac, the default system ruby is
/usr/bin/ruby
How do I properly setup Aptana RadRails if I've installed Rails through RVM?
I followed the install on http://railstutorial.org/ but my script paths don't work: e.g.:
'rails' path: /home/marius/.rvm/gems/ruby-1.8.7-p302#rails3gemset/bin/rails
Detected path: Not Detected
After installing ruby through rvm, I was able to get eclipse to use that install by:
In Eclipse, go to Window -> Preferences.
In the Ruby/Interpreters tab click "Search"
For me this found all of the ruby installs from rvm, and it added them to the interpreters list. I edited the "Name" field to include the version number for convenience.
try to run this in the command line. It will show you real path to the available rail script for current environment.
$ which rails
In Aptana Studio 3 (build: 3.0.8.201201201658) there is no Window -> preferences. If you have a .rvmrc in your project work directory, stating for instance:
rvm use ruby-1.9.3-p0#mygemset
... then Aptana should pick up the correct environment; in this case using ruby-1.9.3-p0 with gemset mygemset. Don't forget to run build install or build update (when you updated your Gemfile) from your project working directory path.
I must add that Aptana Studio 3 seems a bit buggy when it comes to picking up the correct environment, especially when trying to use ruby-debug-ide19.
Did you try with just /home/marius/.rvm/gems/ruby-1.8.7-p302/bin/rails ?
You have to run eclipse/aptana from a terminal session.
Without RVM :
Please type command whereis ruby in console.
you will get the path like /usr/bin/ruby or /usr/local/bin/ruby to check which is correct interpreter path /usr/bin/ruby -v if you get version. that is your interpreter.
With RVM :
Please type command: rvm info
binaries:
ruby: "/home/<USERNAME>/.rvm/rubies/ruby-2.0.0-p247/bin/ruby"
copy this path and paste wherever you need enter you interpreter path.
It worked for me. and I hope it will help others as well.
Cheers!
I am following this tutorial and I've run the command ruby script\server and successfully started the server.
Now, when I run ruby script\generate controller MyTest, it says
'ruby' is not recognized as an internal or external command..
This error message means
you dont' have ruby installed (It's on page 1 of your tutorial)
or
ruby is not in your PATH . In that case, check if the PATH points to the folder where you have installed ruby (on Windows I think it's PATH)
Edit:
If you look at the screenshots of the 1st page, the path to ruby is specified all the time
"c:\ruby\bin\ruby.exe" "c:\ruby\bin\gem" install rails
I did install it on my netbook - I specified to update my PATH but it didnt. After setting up my path correctly, I could type: gem install rails
Sounds like you either haven't installed ruby or it hasn't been added to your PATH environment variable. Use the link text from this page and make sure you open the cmd.exe console AFTER you installed Ruby.
