您没有写入/var/lib/gems/1.9.1目录的权限 [英] You don't have write permissions into the /var/lib/gems/1.9.1 directory

问题描述

错误：执行gem时...（Gem： ：FilePermissionError）
您没有写入 /var/lib/gems/1.9.1 目录的权限。

obs。我在Ubuntu 14上运行。

解决方案

根据这个问题，我看到几个步骤以允许写入 / var / lib / gems ：

1. 创建 gems （如果没有的话）组，然后将自己添加到组中：
   
   

     $ groupadd -f宝石
    $ usermod -aG gems $（whoami）
     




2. 重新进入会话：

     $ sudo -u $（whoami）bash 
     




3. 允许将 gems 组写入 / var / lib / gems / ，并设置 setgid 位：
   
   

     $ chown：gems / var / lib / gems / 
    $ chmod g + sw / var / lib / gems / 
     




4. 尝试将宝石安装到 / var / lib / gems / 。

注意：我强烈建议您通过 rbenv / rvm 将它们保存在本地主文件夹中。请参阅答案，以了解如何正确设置您的项目。

I got this error, for all gem that I try to install:

ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /var/lib/gems/1.9.1 directory.

obs. I'm running on Ubuntu 14.

解决方案

According the question I see a few steps in order to allow writing to /var/lib/gems:

1. Create gems (if not any) group, and add yourself to the group:

   $ groupadd -f gems
   $ usermod -aG gems $(whoami)
   

2. When reenter to the session:

   $ sudo -u $(whoami) bash
   

3. Allow write for a gems group to /var/lib/gems/, and set the setgid bits:

   $ chown :gems /var/lib/gems/
   $ chmod g+sw /var/lib/gems/
   

4. Try installing gems into /var/lib/gems/.

NOTE: I strongly advice you to control rubies and gems via rbenv/rvm keeping them in a local home folder. Please refer to the answer to know how to properly setup your project.
