RVM PATH 未正确设置

Question

我最近在尝试升级我的 ruby​​ 版本时遇到了来自 rvm 的以下错误。

Warning! PATH is not properly set up, '/home/sam/.rvm/gems/ruby-2.2.1/bin' is not at first place,

我的echo $PATH如下：

/usr/local/heroku/bin:/home/sam/.rvm/gems/ruby-2.2.1/bin:/home/sam/.rvm/gems/ruby-2.2.1@global/bin:/home/sam/.rvm/rubies/ruby-2.2.1/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/sam/.rvm/bin:/home/sam/.rvm/bin:/home/sam/.rvm/bin:/home/sam/.rvm/bin

我的 .bashrc 中有以下几行

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"

而且 .bash_profile 有：

[[ -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*

而我的rvm info如下

Warning! PATH is not properly set up, '/home/sam/.rvm/gems/ruby-2.2.1/bin' is not at first place,
         usually this is caused by shell initialization files - check them for 'PATH=...' entries,
         it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
         to fix temporarily in this shell session run: 'rvm use ruby-2.2.1'.

ruby-2.2.1:

    gemset:       ""

我找到了类似问题的解决方案here. 但显然不够接近（建议的解决方案没有效果）。

无论如何，如果有人有任何想法，我将不胜感激。我对 rvm 的来龙去脉有点不知所措，所以我在这里有点摸不着头脑。提前致谢

编辑：

我尝试颠倒我的.bashrc 中两个 rvm 行的顺序，但这并没有解决错误，也没有改变echo $PATH 显示的顺序。

Answer 1

您的 PATH 不以 /home/sam/.rvm/gems/ruby-2.2.1/bin 开头，因为您在 Heroku 工具带路径前面有一行。

您可以通过在终端中运行它来检查这是真的：

PATH=/home/sam/.rvm/gems/ruby-2.2.1/bin:$PATH rvm info

它不应该抱怨。 问题来自 Heroku 工具带以 rvm 不关心的方式修改您的环境。 根据this post，解决方法是更改​​您的.bashrc，如下所示：

### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
# Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

您可以从.bash_profile 中删除 rvm 行

Answer 2

为了解决这个问题，我刚刚更改了我的 .profile 文件：

PATH="$HOME/bin:$HOME/.local/bin:$PATH"

到

PATH="$PATH:$HOME/bin:$HOME/.local/bin"
