前几天，不知道干了啥，比较值得怀疑的是当时执行 brew install supervisor
更新了一堆应用程序，然后只要 cd ~
或者回车一下，就会吐出一堆错误来。

在网上找了N多资料，基本上没有用处。不过在 这里
看到重装 python 2会有用，就试了了下 brew reinstall python@2
，但brew会继续教做人。
... ==> Installing python@2 Error: An exception occurred within a child process: FormulaUnavailableError: No available formula with the name "/usr/local/opt/python@2/.brew/python@2.rb"
继续挖，有叫人从URL安装的， brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/94d572a132a63651739fef1931f540404b7eaa31/Formula/python@2.rb
，试了，可能会有用，但有个警告比较吓人：
Warning: Unsupported installation from a commit URL! Consider using `brew extract python@2 ...` instead!" This will extract your desired python@2 version to a stable tap instead of installing from a commit URL that cannnot receive updates or fixes!
吓得我赶紧儿 Ctrl-C 取消掉。最后解决方式是先 brew uninstall python@2
，然后再 brew reinstall python@2
再次安装，就好了。

测试驱动开发的艺术
Lasse Koskela / 李贝 / 人民邮电出版社 / 20101023 / 59.00元
在传统的软件开发中，开发人员对于代码是否正确心中无底，一切依赖于后期的测试环节。极限编程反其道而行之，主张采用测试驱动开发（TDD）的方法，即通过测试定义所要开发的功能的接口，然后实现功能的开发过程。TDD通过不断地测试推动代码的开发，既简化了代码，又保证了软件质量。 本书采用“手把手”的教学方式，通过大量实例来解释TDD，还专门用几章的篇幅来讲解如何为难于测试的技术编写单元测试。全书内容循......一起来看看 《测试驱动开发的艺术》 这本书的介绍吧!
