ruby-on-rails – rvm gem安装错误？

我正在乱搞 rubygems和rvm并且它工作得非常好但是现在当我尝试安装gem时我得到一个错误

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

它在我做sudo时有效,但在安装gem之前我从未必须这样做.

$gem env

解决方法

看起来您已将root用户设置为使用主文件夹中的rvm install.这意味着当您使用sudo安装gem时,这些文件将属于root.因此,当您尝试像您一样安装gem时,您将收到权限错误.

要修复,你需要将rvm文件夹重新给你(我假设,从你的文件路径,你的用户名是’da’在这里)…

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

为了避免将来发生这种情况,我建议将root的路径设置为自己安装的rvm或系统gem.
