我在使用 yeoman 生成 Angular 应用程序时遇到问题。

Yeoman 似乎做得很好，但是当涉及到 bower install && npm install 时，它在运行 OptiPNG 测试时失败了。

我正在运行 OSX 10.8.3、Node 版本 0.8.18 以及最新版本的 NPM 和 yeoman。

  ✖ 4 of 3 tests failed:

  1) OptiPNG should return path to OptiPNG binary:

我不确定这是否会有所帮助......但我最近在yo. （注意：我当时没有在 OSX 上进行测试，而是在 windows 上进行测试。但根据我对错误的回忆，我认为问题是相同的。）

问题是我更新到了最新yo版本，并且我的 npm 缓存中还残留着一些东西。以下固定的东西：

npm uninstall -g yeoman
npm install -g yo
npm cache clean
npm update -g yo

完成此操作后，我yo angular在一个干净的目录中进行了测试，并且脚手架的创建没有错误。

我有一个类似的问题，在我的项目目录的根目录中尝试了各种运行“bower cache clean”的东西后解决了它。
