First I installed rvm for multi-user using script
\curl -L https://get.rvm.io | sudo bash -s stable
and I added users to rvm group.
and rvm seems worked fine. so I installed ruby 1.9.3 and set 1.9.3 as default
and now I tried to install rails with command
gem install rails
It seems worked fine, but when fetching json-1.7.6.gem and an error occurs.
ERROR: Error installing rails:
ERROR: Failed to build gem native extension.
/usr/local/rvm/rubies/ruby-1.9.3-p374/bin/ruby extconf.rb

Results logged to /usr/local/rvm/gems/ruby-1.9.3-p374/gems/json-1.7.6/ext/json/ext/generator/gem_make.out
So I thought it would be related with permission, so I tried
sudo gem install rails
but then this error occurs.
sudo: gem: command not found
What should I do?
use sudo as follows..
sudo gem install rails
Updated Answer:
our $PATH variable needs to include the exact path to your Ruby's bin directory. Adding a directory to the PATH does not include it's subfolders. Try adding the bin directory via:
export PATH=$PATH:/home/adam/.gem/ruby/1.8/bin
or if you installed the gem using sudo:
export PATH=$PATH:/usr/lib/ruby/gems/1.8/bin
You might want to add this to your .bashrc file, so that you don't have to set this manually every time your open up a new bash.
you can use rvmsudo to run sudo commands. But you should really be using Gemfiles to install gems using Bundler.

I installed ruby 2.6.3 using RVM. later when i try to install rails i am getting following error.
$ gem install rails -v 6.0.2.1
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/local/rvm/gems/ruby-2.6.3 directory.
$ sudo gem install rails -v 6.0.2.1
sudo: unable to execute /usr/bin/gem: No such file or directory
That's because at some point you used sudo to install your rvm. So, the system will require sudo permission to install later gems
When you use command $ sudo gem install rails -v 6.0.2.1, you tell system to use normal directly installed ruby, not via rvm, so it warns you No such /user/bin/gem error
The solution for this is to change ownership of all files in the ~/.rvm directory to current account, as if you're using root account by following command
sudo chown -R $USER ~/.rvm
I've been running in circles trying to install the 'twilio-ruby' gem in my rails app to no avail. Every time I try to bundle install I receive errors around libxml. Below is a part of the error I'm receiving when I add 'twilio-ruby' to the gem-file and try to bundle install:
Errno::EACCES: Permission denied # rb_sysopen - /Users/George/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/libxml-ruby-3.0.0/HISTORY
An error occurred while installing libxml-ruby (3.0.0), and Bundler cannot continue.
Make sure that `gem install libxml-ruby -v '3.0.0'` succeeds before bundling.
Trying to gem install libxml-ruby results in the error below:
ERROR: While executing gem ... (Errno::EACCES)
Permission denied # rb_sysopen - /Users/George/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/libxml-ruby-3.0.0/HISTORY
Any help that points me in the right direction would be much appreciated.
to install correctly rbenv follow the instructions on github for your operating system (Mac or Linux)
rbenv installation
While to better understand this problem, it is connected to security issues. Mac and Linux are Unix based system, where the user logs in and can execute commands on his home directory ~/<user>. If you try to execute a command to run a script in another directory like the root directory / or /bin, you will get an authorization error and you will need to run the command with sudo that stands for system user do.
For this reason, with linux you configure the ~/.bash_profile file
Add ~/.rbenv/bin to your $PATH for access to the rbenv command-line utility.
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
Ubuntu Desktop note: Modify your ~/.bashrc instead of ~/.bash_profile.
Zsh note: Modify your ~/.zshrc file instead of ~/.bash_profile.
so that those command irb, gem, rake, rails when executed from the user they:
Search your PATH for an executable file named rake
Find the rbenv shim named rake at the beginning of your PATH
Run the shim named rake, which in turn passes the command along to rbenv
explanation of shims in rbenv
You can also solve easily this problem by running the command with sudo, but it is not reccommended, as you can read also from the below post where they have the same problem but with rvm,
Why do I get a "permission denied" error while installing a gem?
Im using Ubuntu 15.10. This is the code I write in the terminal
gem install bundler
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /var/lib/gems/2.1.0 directory.
Why is it trying to install it there? of course it doesn't have permissions to install it in the root directory. If I try the same command like this sudo gem install bundler it works. But it is not supposed to be installed as sudo, it gives me problems when creating a new Rails app. What should I do?
You should probably start by running gem env and look at your default environment.
You can change the default installation directory by exporting a different GEM_HOME:
export GEM_HOME=$HOME/.gem/

Rails 4.0 needs RubyGem version 2.0.3, Just update your system by using following command
gem update --system 2.0.3
Run the following command:
sudo apt-get install ruby-dev zlib1g-dev liblzma-dev
Then,
sudo gem install rails
Just a follow up ... on different solution...
it may be that you are on a mac and rails cannot find the right compiler for c headers.
just install xcode from apps store / homebrew or go to terminal ...
$ xcode-select --install
complete the installation and agree on the licensing etc, then ...
$ sudo gem install rails
Got the same issue when installing rails with the command
"gem install rails -v 5.1.2" on windows7, solved after installing "MSYS2 and MINGW development toolchain" (command ridk install then option 3)..It took a while to finish the installation and then i installed rails without any problem
For me this helped:
sudo apt-get install ruby-dev
I could solve this way
rvm use ruby --install --default
and then try again.
gem install rails --no-document
This worked for me:
sudo ln -s /bin/mkdir /usr/bin/mkdir
I kept encountering this error when I ran gem install rails -v 5.2.0:
make: /usr/bin/mkdir: Command not found
make: *** [Makefile:199: .sitearchdir.-.racc.time] Error 127
make install failed, exit code 2
So I ran this command and it fixed it for me:
sudo ln -s /bin/mkdir /usr/bin/mkdir

Try
sudo gem install rails --version 2.0
to install libraries.
For anyone got the error:"Failed to build gem native extension”, while running sudo gem install rails, and it said somethings about "nokogiri".
It is possible because you are using the same ruby version as system is using (for mac user). The solution would be install RVM, use RVM to install another ruby version.
So now you have 2 Ruby versions on your machine, RVM will automatically switch to the newly installed version. now, you can run gem install rails without error and without sudo as well.
i'm running elementary os 5 and what i do is.
sudo gem update --system
and then try again.
sudo gem install rails
On Fedora 30, I ran into this problem "Failed to build gem native extension". The log error was "gcc: fatal error: cannot read spec file ‘/usr/lib/rpm/redhat/redhat-hardened-cc1’: No such file or directory". The solution was found here.
If you installed all the above, but the extensions would still not compile, you are probably running a Fedora image that misses redhat-rpm-config package. In that case gcc compiler would complain about one of the following:
gcc: error: conftest.c: No such file or directory
gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory
To solve this, simply run sudo dnf install redhat-rpm-config.
While installing rails 7 when I ran the command
sudo gem install rails
I got the same errors. I tried several suggestions, but in vain. At last one suggestion from the web helped me. I have been asked to run following command :
sudo apt-get install libmagickwand-dev
and then try again installing rails. Here is the link to that site : https://askubuntu.com/questions/600068/cant-install-a-ruby-package-failed-to-build-gem-native-extension
It worked !!!
I had the same error when installing rails, but I solved it by running the command: gem install rails without adding sudo.

qichunren#zhaobak:~> gem install hpricot
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /opt/ruby-enterprise-1.8.7/lib/ruby/gems/1.8 directory.
Current login user is qichunren, and qichunre user have write permission with .gem dir.I would like to know why gem not install files into my home .gem dir first? Why my gem common first want to install files into /opt/ruby-enterprise-1.8.7/lib/ruby/gems/1.8
Try setting GEM_HOME and GEM_PATH to ~/.gem,
For the current terminal session, just type:
export GEM_HOME=~/.gem
export GEM_PATH=~/.gem
If you want these to be set whenever you open a terminal, add the above commands to your ~/.bashrc file.
For a more comprehensive solution to setting up a custom ruby environment, see this tutorial from Site5KB, which describes using a .gemrc file.
For a systemwide Ruby install, become root. For example:
$ sudo gem install hpricot
However, the modern approach in many circumstances, including in development, is to use a tool that lets you easily install and use Ruby as a normal user. This lets you avoid having to become root. There are a few such tools, and the one I use is RVM.
# install rvm into your ~
$ \curl -sSL https://get.rvm.io | bash -s stable
# install latest version of ruby into your ~
$ rvm install ruby
# installs a gem into your ~
$ gem install $SOME_GEM_NAME
I was getting this error on my shared server through 1and1 hosting.
my solution was adding the --user-install option, which just installs it for your logged in user (which is all you need in a shared server environment)
example; installing sass
gem install sass --user-install
If you're using rbenv and this is happening, you need to add the following to your .bash_profile:
export RBENV_ROOT="$HOME/.rbenv"
if [ -d $RBENV_ROOT ]; then
export PATH="$RBENV_ROOT/bin:$PATH"
eval "$(rbenv init -)"
fi
re-install ruby resolve my problem.
brew install ruby
