我正在尝试运行npm install，为了安装我的项目的依赖项，这在我安装El Capitan（在Mac上）之前一直有效。
我尝试通过以下方式重新安装node和npm：
1.node js installer package
2.nvm
3.homebrew
npm -v 2.14.4

由于此问题，看起来contextify目前无法在Node版本4.x上运行： https://github.com/brianmcd/contextify/issues/180
您可以使用n降级到0.12.7，如下所示： npm install -g n＆amp;＆amp; n 0.12.7
然后这应该工作，你应该能够安装你的deps： npm install -g contextify
答案 1 :(得分：2)
我发现这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项，如果有，我会更新到最新版本并尝试。通常它是有效的，因为模块作者已经修复它（特别是如果它是一个流行的模块）
安装：
npm install npm-check-updates -g
执行命令
ncu
如果您看到较新的模块，请运行：
ncu -u
注意：这会将所有软件包更新为最新模块。还有命令只更新您需要的那些。
