如何在Rails中更改/更新宝石路径路线
[英]How to change/update a gem path route in Rails
问题描述
When I run rake db:migrate , I get an error message that has this line in it: 
当我运行rake db:migrate ，我收到一条包含以下内容的错误消息：
/Users/andy/.rvm/gems/ruby-2.5.0@global/gems/rake-12.3.0/exe/rake:27:in `<top (required)>
but when query the path route I get a different route: 但是当查询路径路线时，我得到了不同的路线：
Unkle-Andy:workspace andy$ gem which rake
/Users/andy/.rvm/gems/ruby-2.5.0/gems/rake-12.3.0/lib/rake.rb
Looking for a way to change/update the path route so that when I run the rake gem it looks for it in /lib instead of /exe . 寻找改变/更新路径路线的方法，以便当我运行rake gem时，它在/lib而不是/exe寻找它。 Or is this normal? 还是正常？

The lib part of path that gem which rake shows is normal; gem which rake显示的gem which rake的路径的lib部分是正常的； it's what before it most likely causes problems - this path and path shown in error message point to two different directories, containing different RVM gemsets. 这是最有可能导致问题的原因-此路径和错误消息中显示的路径指向两个不同的目录，其中包含不同的RVM gemset。 Try resetting your current gemset: 尝试重置当前的宝石集：
rvm gemset use default or rvm gemset use global rvm gemset use default或rvm gemset use global
