RoR'新'命令挂起

Question

我刚刚在轨道上开始红宝石.在终端中,我输入了"rails new TestApp",这就是终端发生的情况:

  create  vendor/assets/stylesheets
  create  vendor/assets/stylesheets/.gitkeep
  create  vendor/plugins
  create  vendor/plugins/.gitkeep
     run  bundle install

它挂在那里.我应该退出它并继续使用该应用程序吗？为什么它不能让我回到终端控制？谢谢.

更新:它问我密码并安装了一些宝石.但每次我创建一个新的rails项目时都会这样做.这是正常的吗？谢谢.

系统正在"挂起",因为它正在生成bundle install的Gemfile中安装所有的gem rails new <project>.这是预期的行为.它要求您输入密码,以便它可以安装一些需要sudo写入的rail文件(最有可能将可执行文件放在您的路径中).

您可以通过传递参数来跳过bundle install调用步骤.在运行应用程序之前,您仍然需要打电话,但至少可以控制它何时发生.rails new--skip-bundlebundle install

--skip-bundle当您知道要更改Gemfile时使用它是很有用的,这样您就不必在几分钟内再次运行它之前等待bundler安装所有gem.
