npm install报错Unexpected end of JSON input while parsing near '...ersion":"4.5.0","depe'

这两天执行 npm install 时会报错误：

这个错误的解决方法有以下几种：

1.删掉package.lock.json

2.清除cache

npm cache clean --force

3.进入下面这个文件夹清除cache
路径：C:/Users/PC/AppData/Roaming/npm-cache
执行：

npm cache clean --force

4.不要用淘宝镜像。

npm set registry https://registry.npmjs.org/
