ruby-on-rails - RVM没有在`fish`中设置我的PATH，但是应该

我使用rvm已经一年半了。
每次调用命令时都会出现rvm路径警告，但其他情况下rvm仍然正常工作。我可能已经用这个链接的说明修正了这个警告：StackOverflow - Getting “Warning! PATH is not properly set up” when doing rvm use 2.0.0 --default
这涉及到将[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"放入一个与我的bash相关的shell配置文件中。
添加一个，或者在调用链中的其他可用文件中添加太多，可能会导致这种奇怪（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路径错误。我当时并不这么认为，但是回顾这个问题，我想知道我是否刚刚将fishshell从大约2.2.0更新到2.5.0，这可能会导致我进一步的实际路径错误（不是警告）……
执行rvm reset没有帮助。
执行rvm get stable --auto-dotfiles似乎对当前终端有帮助，但对其他终端没有帮助，即使在重启时也是如此。决定重新安装。
运行rvm implode。删除或注释掉所有shell配置文件中的所有rvm行。
运行RVM - Integration - Fish Shell，这里也介绍了StackOVerflow - Can't get RVM to switch rubies，其中包括先执行一些RVM - Installing RVM - Quick (guided) Install。
使用这种组合：curl -sSL https://get.rvm.io | bash -s stable --rails --with-default-gems="rails haml" --with-gems="hirb"。
下载了rvmfish函数。
将rvm default配置添加到config.fish。
问题
我的可执行文件版本错误：

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

它是系统ruby，而不是rvm set版本：

⋊> ~ which ruby
/usr/bin/ruby

我没有bundle命令：

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

因此，如果没有bundle帮助我安装gem，我就无法使用rails：

⋊> ~ 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ruby和PATH变量似乎没有更新，如下所示。
我的问题是如何更新这些变量？类似于此链接的内容：StackOverflow - RVM doesn't set correct gem path

You can then rerun your "rails" command.

其他东西
与GEM_PATH更相关，但可能仍然适用，因为bashfish函数在内部使用bash：StackOVerflow - Need to Fix PATH in my bashrc File for RVM
简单的方法，但我需要rvm动态特性工作：StackOverflow - How to set up path for gems with the Fish shell?

最佳答案

某种解决方案
到目前为止，我几乎没有工作，通过作出改变：
grep -E '^rvm|^GEM_PATH|^GEM_HOME'
到：
grep -E '^rvm|^[^=]*PATH|^GEM_HOME'
不知道会导致什么副作用，但从rvm.fish代码来看，这似乎是缺失的。
旁白
旧版本中有^[^=]*PATH\术语，就像我的系统以前的版本一样，也可以在这里随机找到：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中需要它。我的修复特别有效，没有反斜杠，只是简单的管道字符。
非功能替代品
我也尝试了一个没有其他代码的补丁，比如这个：

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

我正在继续添加行，但仍然看到各种错误。首先，我需要“rubies”目录以获得正确版本的ruby，然后用空格修改两个gem路径以获得fish，但我仍然有问题，因此批量使用bash的PATH环境变量并让rvm脚本自行完成工作是目前为止我拥有的最好的方法。

关于ruby-on-rails - RVM没有在`fish`中设置我的PATH，但是应该，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/44574382/
