RVM 没有在“鱼”中设置我的 PATH，但应该是

Question

我已经使用 RVM 一年半了。

在每次命令调用时都有 RVM PATH 警告界面，但除此之外 RVM 仍然正常运行。我可能已经通过以下链接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shell 配置文件之一。

在调用链中的其他可用文件中添加该文件或添加太多文件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”

开始再次收到 RVM PATH 错误。我当时并没有这么想，但是回头看看这个问题，我想知道我是否刚刚将我的fish shell 从大约 2.2.0 更新到了 2.5.0，这可能导致我进一步实际 strong> PATH 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，即使在重新启动时也是如此。决定重新安装。

跑rvm implode。删除或注释掉我所有的 shell 配置文件中的所有 RVM 行。

跑过RVM - Integration - Fish Shell，这里也介绍了StackOVerflow - Can't get RVM to switch rubies，这涉及到先做一些RVM - Installing RVM - Quick (guided) Install。

• 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rvmfish函数。
• 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 设置的版本：

⋊> ~ which ruby
/usr/bin/ruby

我没有捆绑命令：

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

因此，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PATH 和GEM_PATH 变量似乎没有更新，如下所示。

我的问题是问如何更新这些变量？类似于此链接的内容：StackOverflow - RVM doesn't set correct gem path

其他东西

• 更多与 bash 相关，但可能仍然适用，因为 fish rvm 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 动态功能工作：StackOverflow - How to set up path for gems with the Fish shell?

Answer 1

某种解决方案

到目前为止，我几乎无法通过以下方式进行更改：

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

到：

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

不确定会导致什么副作用，但通过查看rvm.fish 代码，这似乎是缺失的。

相关的一边

旧版本中包含^[^=]*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 那是为了转义管道 (|) 字符，但我不明白为什么在单引号内需要这样做。我的修复特别适用于没有反斜杠和简单的管道字符。

非功能替代

我也尝试了一个没有其他代码的补丁，例如这个：

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

我继续向它添加行，但仍然看到各种错误。首先我需要ruby 的正确版本的“rubies”目录，然后用fish 的空格修改两个gem 路径，但我仍然遇到问题，所以将bash 的PATH 环境变量批发和让rvm 脚本自己工作是我迄今为止最好的。
