启动 Ruby on Rails 服务器时如何修复加载错误

Question

我经常收到错误。 例如，当运行 SQLite3 服务器时：

$ rails s
C:/Ruby26-x64/bin/rails:23:in `load': cannot load such file -- C:/Ruby26-x64/lib/ruby/gems/2.6.0/gems/railties-6.0.2.2/exe/rails (LoadError)
        from C:/Ruby26-x64/bin/rails:23:in `<main>'

我尝试了在这里找到的所有不同建议，例如bundle install rails 。 我正在运行 Ruby v. 2.6.5，但在上面的错误中提到了 2.6.0。

$ which -a ruby
/c/Ruby26-x64/bin/ruby
/c/RailsInstaller/Ruby2.3.3/bin/ruby
