Node.js checksum failed 错误解决方案
问题
在某个项目内npm install时，老是报以下错误：
pm ERR! code EINTEGRITY npm ERR! sha1-7Qoe24fAXU2xA3xfj0g9ijtfCCU= integrity checksum failed when using sha1: wanted sha1-7Qoe24fAXU2xA3xfj0g9ijtfCCU= but got sha512-mYQLZnx5Qt1JgB1WEiMCf2647plpGeQ2NMR/5L0HNZzGQo4fuSPnK+wjfPnKZV0aiJDgzmWqqkV/g7JD+DW0qw== sha1-psC74fOPOqC5Ijjstv9Cw0TUE10=.

如何解决
一番摸索后，发现是我自己给npm set config registry 更改了源。改回官方的npm源就能解决问题：
npm config set registry https://registry.npmjs.org
或
npm config set registry https://registry.npm.taobao.org
