终端启动 Mac OS X 上的宝石路径损坏

Question

当打开一个新终端时，我得到：

Traceback (most recent call last):
        3: from /usr/local/bin/bundle:22:in `<main>'
        2: from /usr/local/Cellar/ruby/2.6.5/lib/ruby/2.6.0/rubygems/core_ext/kernel_gem.rb:65:in `gem'
        1: from /usr/local/Cellar/ruby/2.6.5/lib/ruby/2.6.0/rubygems/dependency.rb:323:in `to_spec'
/usr/local/Cellar/ruby/2.6.5/lib/ruby/2.6.0/rubygems/dependency.rb:311:in `to_specs': Could not find 'bundler' (>= 0) among 7 total gem(s) (Gem::MissingSpecError)
Checked in 'GEM_PATH=/Users/tkellogg/.gem/ruby/2.6.0:/usr/local/lib/ruby/gems/2.6.0:/usr/local/Cellar/ruby/2.6.5/lib/ruby/gems/2.6.0', execute `gem env` for more information

Bash 配置文件如下所示：

. ~/.bashrc

# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"

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

bashrc 的样子；

# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"

我已将默认系统 ruby​​ 设置为 2.6.5，并且我已升级自制软件。

有什么想法吗？

运行bundle update --bundler 得到env: ruby: Argument list too long

这是gem env的结果：

Ignoring gem-wrappers-1.4.0 because its extensions are not built. Try: gem pristine gem-wrappers --version 1.4.0
Error loading RubyGems plugin "/Users/me/.rvm/rubies/ruby-2.6.5/lib/ruby/gems/2.6.0/gems/gem-wrappers-1.4.0/lib/rubygems_plugin.rb": cannot load such file -- gem-wrappers (LoadError)

Answer 1

看起来您可能已经使用 Homebrew 安装了 ruby​​，但您尝试使用 RVM，这可能会导致问题。如果是这种情况，您可能应该重新开始。

首先卸载 RVM

rvm implode

然后卸载 ruby​​

brew uninstall ruby

然后重新安装 RVM 参见https://rvm.io/rvm/install

根据您的gem env 更新您的PATH 变量显然搞砸了。您可以尝试通过查看this question 的答案来修复它，也可以try this solution。但设置一个新的用户帐户并从新的 shell 设置开始，然后重新运行上述步骤可能会更容易。
