升级到Catalina后，我尝试安装CocoaPods。
我用brew安装节点和监视者，然后使用sudo gem安装cocoapods。
在终端中使用pod命令时，出现以下错误：
11: from /Users/myuser/.gem/ruby/2.6.0/bin/pod:23:in `<main>'

/ Users / myuser / .gem / ruby / 2.6.0 / gems / cocoapods-1.8.4 / lib / cocoapods / executable.rb：97：在`expand_path'中：用户bin不存在（ArgumentError）
如果有人能给我提示如何解决我的问题，我将不胜感激。
ArgumentError遇到相同的问题。安装Cocoapods并尝试执行“ pod设置”后，错误消息显示：/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.7.5/lib/cocoapods/executable.rb:97：在“ expand_path”中：用户工具不存在（ArgumentError）
