gem install rails错误：执行gem时（Errno :: EACCES） [英] gem install rails ERROR: While executing gem ... (Errno::EACCES)

问题描述

我不知何故把我的$ PATH搞砸了。 （改变它）和我的红宝石和铁轨宝石不工作。我努力解决这个问题的方法是重新安装RVM。现在我的红宝石在码头工作良好。
运行 gem install rails 我得到了这样的欢迎：

权限被拒绝 - /Users/emKaro/.rvm/gems/ruby-2.0.0-p247/gems/atomic-1.1.13/test/test_atomic.rb


当我尝试通过 sudo gem install rails 安装rails时，出现此错误：

错误：执行gem时（Errno :: EACCES）

安装了命令行工具的XCode也已安装。即使继续安装GCC，但在尝试安装rails时也会遇到同样的错误。

这是完整的错误消息

谢谢@Christoph
唯一有助于实际移除RVM的代码文件夹与
sudo rm -rf〜/ .rvm /
我只尝试卸载并且不起作用。因此，删除文件夹，然后重新安装RVM即可完成这项工作。

解决方案

像Dave指出那里，应该没有必要sudo任何Gem安装。您可以尝试重置您的RVM目录上的权限：

  sudo chown -R emKaro：〜/ .rvm / 
  

并再次尝试您的Gem instllation。如果不行，你应该考虑删除你的RVM安装并重新开始：

  sudo rm -rf〜/。 rvm /＃删除你的RVM目录
  

实际上，没有必要在任何情况下使用sudo。

I somehow messed my $PATH up. (changed it) and my ruby and rails gems weren't working. What I did in efforts to fix this was to reinstall RVM. Now my ruby works fine in the Terminal. On running gem install railsI get greeted with this:

Permission denied - /Users/emKaro/.rvm/gems/ruby-2.0.0-p247/gems/atomic-1.1.13/test/test_atomic.rb

When I try to install rails through sudo gem install rails, I get this error:

ERROR: While executing gem ... (Errno::EACCES)

I have XCode installed with Command-Line tools installed as well. Even went ahead to install GCC but get the very same error when I try to install rails.

This is the full error message

I am the admin of my computer and running Mac OS 10.8.3. I'd appreciate some help with the rails install.

EDIT: Thanks @Christoph The only code that helped was to actually remove the RVM folder with sudo rm -rf ~/.rvm/ I tried only to uninstal and it didn't work. So removing the folder and then reinstalling RVM does the job.

解决方案

Like Dave pointed out up there, there should be no need to sudo any Gem installation. You could try to reset the permissions on your RVM directory:

sudo chown -R emKaro: ~/.rvm/

and try your Gem instllation again. If that doesn't work out, you should consider removing your RVM installation and start over:

sudo rm -rf ~/.rvm/   # remove your RVM directory

There should really be no need for using sudo in any of this.
