安装OS X El Capitan后安装NPM
我试图运行npm install，为了安装我的项目的依赖关系，在安装El Capitan（在Mac上）之前，这是工作的。
我尝试通过以下方式重新安装节点和npm：
1.node js安装程序包
2.nvm
3.homebrew
npm -v 2.14.4
节点-v v4.1.1

你可以使用n降级到0.12.7，如下所示：npm install -gn && n 0.12.7
那么这应该工作，你应该能够安装你的代价：npm install -g contextify
我发现它通常是因为其中一个依赖项与节点4.1.1不兼容通常我使用npm-check-update（ ncu ）来查看是否有最新版本的依赖关系，如果是，我更新到最新版本。 通常它的工作原理是模块作者已经修复了它（特别是如果它是一个stream行的模块）
安装： npm install npm-check-updates -g
运行： ncu
如果您看到较新的模块，请运行：
ncu -u
注意：这将所有软件包更新到他们最新的模块。 还有命令只更新你需要的。
