如何在没有sudo的情况下安装宝石 [英] how to install gems without sudo

问题描述

在我所有的宝石安装中，我必须做sudo？所以

sudo gem install rails

将只有工作，而只有

gem install rails

不起作用。如何补救它？

我已安装rvm -

  murtaza @ murtaza-dev：〜$ $ rvm 
 /home/murtaza/.rvm/bin/rvm 
 
 murtaza @ murtaza-dev：〜$ which gem 
 / home / murtaza / .rvm / rubies / ruby​​-1.9.3-p194 / bin / gem 
  

然而，我是当我使用gem进行任何操作时也会收到此警告 -

  murtaza @ murtaza-dev：〜$ gem 
 / home / murtaza / .rvm / rubies / ruby​​-1.9.3-p194 / bin / gem：4：警告：PATH中不安全的可写dir / opt，模式040777

我使用 curl重新安装了rvm -L get.rvm.io | bash -s stable --auto （没有sudo）。

然而，当我尝试安装gem时，它给了我下面的错误 -

  murtaza @ murtaza-dev：〜$ gem install rails 
 /home/murtaza/.rvm/rubies/ruby-1.9.3-p194/bin/gem:4：warning：不安全的可写入目录/ opt在PATH中，模式040777 
错误：执行gem时（Errno :: EACCES）
权限被拒绝 -  /home/murtaza/.gem/specs

出现错误 -

 murtaza @ murtaza-dev：〜$ gem install rails 
 /home/murtaza/.rvm/rubies/ruby-1.9.3-p194/bin/gem:4：警告：PATH中不安全的可写dir / opt，模式040777

解决方案
使用 chown  .rvm 和 .gem 目录中的c $ c>返回给您的用户。您可能之前使用过 sudo ，并且它搞砸了许可。
  sudo chown -R用户名：group〜/ .rvm 
 sudo chown -R用户名：group〜/ .gem 
  
当然，将用户名更改为您的用户名并将其分组为   
On all my gem installs I have to do sudo ? So 

  
sudo gem install rails
will work, while only 

  
gem install rails
will not work. How do I remedy it ?


I have rvm installed - 
murtaza@murtaza-dev:~$ which rvm
/home/murtaza/.rvm/bin/rvm

murtaza@murtaza-dev:~$ which gem
/home/murtaza/.rvm/rubies/ruby-1.9.3-p194/bin/gem
However I am also getting this warning when I do any operations with gem - 
murtaza@murtaza-dev:~$ gem
/home/murtaza/.rvm/rubies/ruby-1.9.3-p194/bin/gem:4: warning: Insecure world writable dir /opt in PATH, mode 040777
EDIT

I have reinstalled rvm using curl -L get.rvm.io | bash -s stable --auto (without sudo). 

However still when I try installing gem it gives me the following error - 
murtaza@murtaza-dev:~$ gem install rails
/home/murtaza/.rvm/rubies/ruby-1.9.3-p194/bin/gem:4: warning: Insecure world writable dir /opt in PATH, mode 040777
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied - /home/murtaza/.gem/specs
EDIT

I did chown on the whole thing but still getting the error - 
murtaza@murtaza-dev:~$ sudo chown murtaza.murtaza -R ~/.rvm/*


 murtaza@murtaza-dev:~$ gem install rails
    /home/murtaza/.rvm/rubies/ruby-1.9.3-p194/bin/gem:4: warning: Insecure world writable dir /opt in PATH, mode 040777
    ERROR:  While executing gem ... (Errno::EACCES)
        Permission denied - /home/murtaza/.gem/specs

解决方案
Use chown on the whole .rvm and .gem directories back to your user. You probably used sudo before and it screwed up permissions.
sudo chown -R username:group ~/.rvm
sudo chown -R username:group ~/.gem
Of course, change username to your username and group to your group
