rvm gem安装错误？

Question

我瞎搞与RubyGems的和RVM和它的工作完全正常，但现在，当我尝试安装一块宝石，我得到一个错误

gem install railsERROR: While executing gem ... (Errno::EACCES) Permission denied - /Users/da/.rvm/gems/ruby-1.9.2-p180/gems/bundler-1.0.11/.gitignore

当我做须藤它的工作原理，但我从来没有这样做之前安装一个宝石。

看起来您已将root用户设置为使用位于您的主文件夹中的rvm install。这意味着当您使用sudo安装gem时，这些文件将属于根目录。所以，当你尝试安装一个宝石时，你会得到许可错误。

要解决，你需要chown将此文件夹RVM还给你（我假设，从你的文件路径，您的用户名是“达”在这里）...

sudo chown -R da:da /Users/da/.rvm 

为了避免这种情况在将来会发生，我建议设置root的路径为自己安装的rvm或系统宝石。
