我正在尝试创建一个新的 Rails 项目,当我运行 rails new appname 时它告诉我

Could not find debugger-1.6.8 in any of the sourcesRun `bundle install` to install missing gems.

然后当我运行 bundle install 时出现这个错误

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.    /Users/username/.rvm/rubies/ruby-2.1.4/bin/ruby -r ./siteconf20141213-76431-12dyum4.rb extconf.rb *** extconf.rb failed ***Could not create Makefile due to some reason, probably lack of necessarylibraries and/or headers.

我知道调试器不适用于 Ruby 2.1.4,那么如何让 bundler 停止尝试安装它呢?我必须使用 Rails 应用程序模板吗?

最佳答案

所以对于这个确切的情况——从您的 Gemfile 中注释掉或删除它以及任何依赖它的 gem(查看 Gemfile.lock)你的项目,然后运行 ​​bundle install

Rails 4.1.8 实际上生成了一个应用程序的 Gemfile,其中 debugger 被注释掉了,所以它应该已经可以正常工作了。

如果你真的需要一个调试器,你可以使用byebug ,Ruby 2.0+ 的 debugger 的替代品。在即将发布的 Rails 4.2.0 版本中,它是 already baked into the generator .

创建新应用时,您还可以添加选项-B--skip-bundle运行 bundle install 创建应用框架后。然后您可以修复您的 Gemfile 并在项目文件夹中自行运行 bundle install。不过,这只会为您节省一点时间。
