`bundle exec跟踪rspec / rake任务中的new`

Question

我正在测试在轨道上添加一些生成器的宝石。

为了测试，我有一个瑞克任务，该任务准备一个新的Rails应用程序，安装我的gem，然后运行生成器。

问题是，在耙任务（spec:prepare）中，我无法使它正常工作：bundle exec rails new test_app...

如果我放弃bundle exec，一切都很好。

最接近成功的方法是这样的：

require "bundler/gem_tasks"
require "rspec/core/rake_task"

RSpec::Core::RakeTask.new(:spec)

namespace :spec do
  task :prepare do
    Dir.chdir('spec') do
      sh('rm -rf test_app')
      Bundler.with_clean_env do
        sh('rails -v')
        # works: sh('rails new test_app -T') # works !
        sh('bundle exec rails new test_app -T')  # fails ...
      end
      # ... more stuff but doesn't get this far unless I don't use bundler above
      end
    end
  end
end

task :default => :spec

基于以上内容，我在Gemfile目录中具有以下spec：

gem 'rails', '~> 6.0'

这成功创建了一个Rails应用程序结构，然后运行捆绑安装，但随后出现此错误：

Bundle complete! 14 Gemfile dependencies, 66 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
         run  bundle binstubs bundler
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.
         run  bundle exec spring binstub --all

您可以使用-B [--skip-bundler]跳过捆绑程序。您可以使用--skip-spring跳过弹簧。

[您也可以使用-p [--pretend]选项进行空运行，它不会生成文件，而只是写出有关stdout输出的期望，它将比实际生成应用程序快得多。
