我有一个Node.js应用程序。当我尝试运行时，npm install它与此挂起：
loadIdealTree:loadAllDepsIntoIdealTree: sill install loadIdealTree
npm install --verbose 给了我一些额外的信息：
npm info it worked if it ends with ok

我遇到了其他人遇到这种情况的情况，但以下情况似乎可以解决他们的问题。它不能解决我的问题：
npm set registry http://registry.npmjs.org/
遇到了同样的问题，此评论在这里为我解决了：
Try to remove ‘package-lock.json’ file from directory where ‘package.json’ locate.
//本次从淘宝仓库源下载
npm --registry=https://registry.npm.taobao.org install
使用cnpm命令代替npm
使用cnpm命令代替npm
// 安装cnpm命令,不会改变npm的源
npm install -g cnpm --registry=https://registry.npm.taobao.org
//使用
cnpm install
修改npm的源
设置npm的源，可以设置多个源，但是只有一个是生效的
//设置淘宝源
npm config set registry https://registry.npm.taobao.org
//设置公司的源
npm config set registry http://127.0.0.1:4873
//查看源，可以看到设置过的所有的源
npm config get registry
修改npm配置文件
编辑 ~/.npmrc 加入下面内容
registry = https://registry.npm.taobao.org
