RVM没有在`fish`中设置我的PATH，但应该是

标签： ruby-on-rails ruby shell fish

我现在已经使用RVM一年半了。

每次命令调用都有RVM PATH警告表面，但RVM仍然正常运行。我可能已使用此链接中的说明修复了该警告：StackOverflow - Getting “Warning! PATH is not properly set up” when doing rvm use 2.0.0 --default 这涉及将[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"放入我的bash相关的一个shell配置文件中。

在调用链的其他可用文件中添加一个或太多，可能会导致这种奇怪的（主要是？）美学错误：SuperUser - Why am I having / how can I fix this error: “shell_session_update: command not found”

再次开始获取RVM PATH错误。我当时没有想到，但回头看问题，我想知道我是否刚刚将我的fish shell从2.2.0更新到2.5.0，这可能会导致我的进一步实际 PATH错误（不是警告）......

执行rvm reset没有帮助。

执行rvm get stable --auto-dotfiles似乎有助于当前终端，但其他人，即使重启也是如此。决定重新安装。

跑rvm implode。删除或注释掉了所有shell配置文件中的所有RVM行。

通过RVM - Integration - Fish Shell，StackOVerflow - Can't get RVM to switch rubies此处也介绍了RVM - Installing RVM - Quick (guided) Install，其中涉及首先执行StackOverflow - RVM doesn't set correct gem path部分内容。

  • 使用此组合：curl -sSL https://get.rvm.io | bash -s stable --rails --with-default-gems="rails haml" --with-gems="hirb"。
  • 下载了rvm fish功能。
  • 将rvm default配置添加到config.fish。

问题

我的ruby可执行文件版本错误：

⋊> ~ ruby -v
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]

这是系统ruby，而不是RVM-set版本：

⋊> ~ which ruby
/usr/bin/ruby

我没有捆绑命令：

⋊> ~ which bundle
⋊> ~ bundle
fish: Unknown command 'bundle'
⋊> ~ functions bundle

因此我不能使用Rails而不帮助我安装gem：

⋊> ~ rails
Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.

我的PATH和GEM_PATH变量似乎没有更新，如下所示。

我的问题是如何让这些变量更新？与此链接类似的内容：StackOVerflow - Need to Fix PATH in my bashrc File for RVM

某种解决方案

到目前为止，通过以下方式进行更改，我几乎没有工作：

grep -E '^rvm|^GEM_PATH|^GEM_HOME'

为：

grep -E '^rvm|^[^=]*PATH|^GEM_HOME'

不确定会导致哪些副作用，但是从rvm.fish代码看起来似乎缺失了。

相关的一边

旧版本中包含^[^=]*PATH\字词，就像我系统的早期版本一样，也可以在此处随机找到：GitHub Gist - ToniRib/rvm.fish 这是为了转义管道（|）字符，但我不明白为什么在单引号内需要它。我的修复工作专门没有反斜杠，只有普通的管道字符。

非功能性替代

我已经尝试过没有其他代码的补丁，例如：

and set -xg GEM_PATH (echo $GEM_PATH | sed 's/ /:/g')
and set -xg PATH (echo $GEM_PATH | sed 's/:/ /g') $MY_RUBY_HOME/bin $PATH

我正在继续为其添加行，但仍然会看到各种错误。首先，我需要＆＃34;红宝石＆＃34; ruby的正确版本的目录，然后使用fish的空格修改了两个宝石路径，但我仍遇到问题，因此请bash PATH环境变量批发并让rvm脚本做自己的工作是我迄今为止最好的。
