LoadError：無法加載此類文件 - 等等

Question

在 Mac OS BigSur 上使用 ruby-build 和 rbenv 升級到 ruby 2.7.2 后，我看到了這個錯誤。

導軌 6.0.3.5

≻ bundle exec rspec spec/acceptance/roles_spec.rb    
An error occurred while loading ./spec/acceptance/roles_spec.rb. - Did you mean?
                    rspec ./spec/acceptance/users_spec.rb


Failure/Error: require File.expand_path('../config/environment', __dir__)

LoadError:
  cannot load such file -- etc
# ./config/application.rb:5:in `<top (required)>'
# ./config/environment.rb:2:in `require_relative'
# ./config/environment.rb:2:in `<top (required)>'

No examples found.

Application.rb:5 - require "rails"

我試圖創建一個全新的 Rails 項目，它具有相同的軌道和 ruby 版本，運行 rake rspec 沒有同樣的問題。

執行以下操作后，此問題得到解決：

• 刪除 bootsnap 緩存：

  rm -rf tmp/緩存/bootsnap*

這可能已經解決了這個問題，但我也這樣做了：

• 使用 ruby 2.7.3
• bundle update bootsnap simplecov安裝 bootsnap 1.7.5（原為 1.7.2）
