npm ERR! Cannot set properties of null (setting ' dev' )
删除node_modules、package-lock.json、yarn.lock
npm config get registry 查看自己的仓库源
正常遇到这种报错,直接在集成终端输入以下任意一个命令即可:
npm config set registry http:/registry.npmmirror.com/
npm install --force --registry=https://registry.npmmirror.com
--
本次项目所用的命令:
npm install --force --registry=https://registry.npmmirror.com; cnpm i
image-webpack-loader -D
yarn config set registry https://registry.npmmirror.com
然后npm装第三方组件库的依赖就没有问题啦,运行马上成功
