这似乎是另一个全局安装的RVM问题，不是吗？在你的主目录下安装怎么样

（请参阅“单用户安装位置：~/.rvm/”）

另外，需要考虑的是：

---

好的，所以我通过卸载rvm修复了它

rvm implode

这将删除rvm/目录和其中构建的所有rubies。为了删除rvm的最终跟踪，您还需要删除rvm gem：

gem uninstall rvm

---

如果我错误地进行了全局安装。我还可以在我的主目录下安装吗？@CodeCrack是的，你可以。只需为本地用户安装它，并从

.bashrc

/

.bash_profile

@МаъСъъъ仅获取/opt/local/bin:/opt/local/sbin:中删除指向全局rvm的所有链接即可profiles@CodeCrack添加到

.bash_profile

：

如果[-z“$MY_RUBY_HOME”-a-s“$HOME/.rvm/scripts/rvm”]；然后源“$HOME/.rvm/scripts/rvm”；fi

，并重新加载bash会话请不要在root下安装rvm/rbenv，也不要在那里使用它们。如果您需要为bundler指定一些设置，以便将gem保存在项目文件夹中。@dd1919该命令给了我“运行时出错”。/configure--prefix=/usr/local/rvm/rubies/ruby-2.1.5--disable install doc--enable shared'，显示/usr/local/rvm/log/1418844250_ruby-2.1.5/configure.log的最后15行：/usr/local/rvm/log/1418844250_ruby-2.1.5/configure.log:运行configure时没有这样的文件或目录出错。正在停止安装。错误
