Question

我正在运行MacOS 10.14，并且当我按照此处的说明进行操作时： https://mailcatcher.me/ 在RVM标题下，以便为mailcatcher gem生成RVM包装器，我得到以下输出（出于上下文，我已经添加了一些命令）：

~ $ rvm list
   ruby-2.1.3 [ x86_64 ]
   ruby-2.3.1 [ x86_64 ]
=* ruby-2.6.2 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

~ $ rvm gemset list

gemsets for ruby-2.6.2 (found in /Users/stephen/.rvm/gems/ruby-2.6.2)
=> (default)
   global
   pipe_dream-5.2

~ $ rvm default@mailcatcher --create do gem install mailcatcher

# Wrapper

Show/regenerate wrappers.

NOTE: This command delegates to 'gem wrapper' => <https://github.com/rvm/gem-wrappers>

## Usage

Show paths and generated wrappers:

    rvm wrapper show


Show path to generated wrapper:

    rvm wrapper show executable_name

Where `executable_name` is something like `ruby` or `rake`.


It is also possible to generate a wrapper for external scripts that require ruby:

    rvm wrapper /full/path/to/script

Where `/full/path/to/script` is full path to existing script


Wrappers are generated automatically, but it is possible to rerun the process:

    rvm wrapper regenerate


Documentation:

    rvm wrapper [help]

~ $

第一个命令似乎成功执行，因为它成功创建了一个新的“ mailcatcher” gemset：

~ $ rvm gemset list

gemsets for ruby-2.6.2 (found in /Users/stephen/.rvm/gems/ruby-2.6.2)
=> (default)
   global
   mailcatcher
   pipe_dream-5.2

尽管最后一个命令只是打印出rvm wrapper的用法。

运行mailcatcher不起作用，尽管专门切换到gemset可以使它起作用，请参见下文：

~ $ mailcatcher
-bash: mailcatcher: command not found
~ $ rvm gemset use mailcatcher
Using ruby-2.6.2 with gemset mailcatcher
~ $ mailcatcher
Starting MailCatcher
==> smtp://127.0.0.1:1025
/Users/stephen/.rvm/gems/ruby-2.6.2@mailcatcher/gems/thin-1.5.1/lib/thin/server.rb:104: warning: constant ::Fixnum is deprecated
==> http://127.0.0.1:1080/
*** MailCatcher runs as a daemon by default. Go to the web interface to quit.

尽管生成RVM包装器的全部目的是使mailcatcher可以在任何地方运行，而不必专门选择“ mailcatcher” gemset。知道为什么最后一个命令只是打印出rvm wrapper用法，而不是实际创建包装器吗？

尝试为mailcatcher创建一个rvm包装器，只是带来了rvm包装器的用法。
