无法在测试环境中加载宝石 [英] cannot load gems in test environment

问题描述

我之前可以运行测试，现在由于某些原因我无法运行。 b

现在和之后发生的事情是我供应商 activesupport （但是我已经取消了这些更改，实际上我处于完全独立/不相关的分支） 。 我在工作期间运行的两个命令 activesupport 我不熟悉 bundle --deployment 和 bundle - 无部署。再次，我相信我解开了与这些更改有关的所有事情（至少就 git status 而言） - 我总是运行 git status ，并且知道所有的代码库变化）。

我知道其他人有类似的，但不是这个确切的问题： https：// stackoverflow.com/search?q=require+cannot+load+such+file+LoadError

我在玩弄 activesupport 以下内容：
如何提供active_support的修改版本，以便在我的Rails应用程序中使用它？

我尝试将供应商 activesupport 分支推送到分段存储：

无论如何，重点在于我的应用程序有效（即所有的gem显然都安装好了， Gemfile 和 Gemfile.lock 完好无损），但我无法运行测试：

  /Users/bsimpson/.rvm/gems/ruby-2.0.0-p481@books/gems /activesupport-4.0.5/lib/active_support/dependencies.rb:229:in`require'：无法加载这样的文件 -  minitest / rails（LoadError）
 from /Users/bsimpson/.rvm/gems/ruby -2.0.0-p481@books/gems/activesupport-4.0.5/lib/active_support/dependencies.rb：229：在`block in require'
 from /Users/bsimpson/.rvm/gems/ruby- 2.0.0-p481@books/gems/activesupport-4.0.5/lib/active_support/dependencies.rb：214：在`load_dependency'
 from /Users/bsimpson/.rvm/gems/ruby-2.0.0 -p481@books/gems/activesupport-4.0.5/lib/active_support/dependencies.rb：229：在'require'中
从/ Volumes / MyHD / Users / bsimpson / Dev / books / books / test / test_helper .rb：10：在< top（required）>'
 from test / controllers / photos_controller_test.rb：1：'require'
 from test / controllers / photo s_controller_test.rb：1：在< main>'
  

如果我注释掉 10 test / test_helper.rb ，它只是抱怨下一个 require > line。



  dependencies.rb：229：in'require'：无法加载这样的文件 -  minitest / rails / capybara LoadError）
 ... 
 test / test_helper.rb：14：<< top（required）>'
  

当我注释掉 14 时，它会抱怨下一个 require 行，等等...

因此，在测试环境中，gem aren'没见过。想法？

.bundle / config

  --- 
 BUNDLE_WITHOUT：development：test 
  

解决方案

配置 BUNDLE_WITHOUT：development：test 告诉Bundler不要从开发和<$ c $加载宝石c> test 组。由于这是您唯一的配置设置，因此您可以安全地删除 .bundle / config 文件，并且应该返回给您工作。

或者，您可以保留该文件并仅删除该行。

有可能当您运行 bundle - 部署，你实际上运行了 bundle --deployment - 没有开发测试？这些选项通常一起使用，并且传递给 bundle install （或 bundle ）的选项不带子命令，其中缺省值至 install ）会记住在 bundle / .config 文件中。这些选项在被明确删除之前是粘性的，所以如果你使用 - 没有标志一次，你需要编辑文件来恢复这些组。

另请注意，通常从git中排除 .bundle / config ，因此请检查 git状态不会告诉你它是否改变。这些设置通常是依赖于机器的，所以最好将它从git中排除。

• My app works.
• I was able to run tests before, and now for some reason I can't.
• What happened between now and then is that I vendorized activesupport (but I have since undone those changes, and in fact I am in a totally separate/unrelated branch).
• Two commands I ran during my work on activesupport that I am unfamiliar with are bundle --deployment and bundle --no-deployment. Again, I believe I undid everything related to those changes (at least as far as git status is concerned - I always run git status, and am aware of all codebase changes).

I am aware that other people have had similar, but not this exact problem: https://stackoverflow.com/search?q=require+cannot+load+such+file+LoadError

I was playing around with vendorizing activesupport following this: How to vendor a modified version of active_support such that it is used in my Rails app?

And I had trouble when I tried pushing the vendorized activesupport branch to staging: Where is 'elsewhere' in "run `bundle install` elsewhere"?

Anyway, the point is that my app works (i.e. all the gems are obviously installed, Gemfile and Gemfile.lock are intact), yet I cannot run tests:

/Users/bsimpson/.rvm/gems/ruby-2.0.0-p481@books/gems/activesupport-4.0.5/lib/active_support/dependencies.rb:229:in `require': cannot load such file -- minitest/rails (LoadError)
  from /Users/bsimpson/.rvm/gems/ruby-2.0.0-p481@books/gems/activesupport-4.0.5/lib/active_support/dependencies.rb:229:in `block in require'
  from /Users/bsimpson/.rvm/gems/ruby-2.0.0-p481@books/gems/activesupport-4.0.5/lib/active_support/dependencies.rb:214:in `load_dependency'
  from /Users/bsimpson/.rvm/gems/ruby-2.0.0-p481@books/gems/activesupport-4.0.5/lib/active_support/dependencies.rb:229:in `require'
  from /Volumes/MyHD/Users/bsimpson/Dev/books/books/test/test_helper.rb:10:in `<top (required)>'
  from test/controllers/photos_controller_test.rb:1:in `require'
  from test/controllers/photos_controller_test.rb:1:in `<main>'

If I comment out line 10 of test/test_helper.rb, it just complains about the next require line.

dependencies.rb:229:in `require': cannot load such file -- minitest/rails/capybara (LoadError)
...
test/test_helper.rb:14:in `<top (required)>'

And when I comment out line 14, it complains about the next require line, and so on...

So it seems that in the test environment, the gems aren't seen. Thoughts?

.bundle/config

---
BUNDLE_WITHOUT: development:test

解决方案

The configuration BUNDLE_WITHOUT: development:test tells Bundler not to load gems from the development and test groups. Since this is your only configuration setting, you can safely delete the .bundle/config file and things should go back to working for you.

Alternatively, you could leave the file and only delete that line.

Is it possible that when you ran bundle --deployment, you actually ran bundle --deployment --without development test? These options are commonly used together, and options passed to bundle install (or bundle without a sub-command, which defaults to install) are remembered in the bundle/.config file. These options are "sticky" until they are explicitly removed, so if you use the --without flag once, you'll need to edit the file to get those groups back.

Also note that .bundle/config is usually excluded from git, so checking git status won't tell you if it changed. These settings are often machine-dependent, so it's a good idea to keep it excluded from git.
