如何在使用RVM后使用rbenv

Question

我使用了RVM，但现在我试图使用rbenv进行测试，因为它在我喜欢的教程中使用。 我用自制软件安装了rbenv。然后我注释掉在加载RVM行我~/.bash_profile：

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile 

#[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* 


eval "$(rbenv init -)" 
export PATH="$HOME/.rbenv/shims:$PATH" 

我安装了Ruby：

$ rbenv install 2.2.1 
$ rbenv global 2.2.1 

但是当我尝试安装Rails我得到这个错误：

RVM和rbenv有可能工作吗？

Answer 1

"Gem files will remain installed in /Users/romenigld/.rvm" 

使它看起来像RVM仍然试图控制你的Ruby安装。

RVM与rbenv不兼容。每the rbenv docs：

rbenv is incompatible with RVM. Please make sure to fully uninstall RVM and remove any references to it from your shell initialization files before installing rbenv.

我强烈建议阅读整个rbenv文档;它涵盖了这一点，以及使用增强使用rbenv的插件。
