Question

尝试在Windows上执行“ rails test”时遇到问题。

问题：

非常感谢您的帮助。

可能与Rails Issue #34410 Windows support for parallelization and instrumenter

有关

今天（2019年11月底）仍然存在问题

$ rails test
Traceback (most recent call last):
    28: from bin/rails:9:in `<main>'
    ...
     8: from C:/Ruby26-x64/lib/ruby/gems/2.6.0/gems/activesupport-6.0.1/lib/active_support/testing/parallelization.rb:58:in `initialize'
     7: from C:/Ruby26-x64/lib/ruby/2.6.0/drb/drb.rb:1715:in `start_service'
     6: from C:/Ruby26-x64/lib/ruby/2.6.0/drb/drb.rb:1715:in `new'
     5: from C:/Ruby26-x64/lib/ruby/2.6.0/drb/drb.rb:1403:in `initialize'
     4: from C:/Ruby26-x64/lib/ruby/2.6.0/drb/drb.rb:772:in `open_server'
     3: from C:/Ruby26-x64/lib/ruby/2.6.0/drb/drb.rb:804:in `auto_load'
     2: from C:/Ruby26-x64/lib/ruby/gems/2.6.0/gems/zeitwerk-2.2.1/lib/zeitwerk/kernel.rb:23:in `require'
     1: from C:/Ruby26-x64/lib/ruby/gems/2.6.0/gems/zeitwerk-2.2.1/lib/zeitwerk/kernel.rb:23:in `require'
     C:/Ruby26-x64/lib/ruby/2.6.0/drb/unix.rb:6:in `<top (required)>': UNIXServer is required (LoadError)

错误消息的重要部分来自 testing / parallelization.rb 。

在test / test_helper.rb中：添加“带有线程”：

parallelize(workers: :number_of_processors, with: :threads)

但是，仅此一项并不能解决问题。我也有在Gemfile中将sass-rails升级到版本6（我之前有5）：

gem 'sass-rails', '>= 6'

并进行捆绑更新。

为什么涉及到无礼是个谜。

Answer 2

从this article看来，此问题似乎来自使用Unix套接字的应用程序，Windows不支持该套接字。

我强烈建议您在Docker中运行该应用程序。这将解决您的问题，但是-当然-不是本机Windows体验。

Windows上的Rails测试错误“需要UNIXServer（LoadError）”
