npm node.js javascript node

今天查看了项目的node_modules文件，有2.78G，好家伙，占用空间有点大，然后就删掉了node_modules和package-lock.json文件，重新执行npm install，然后就报错了，之前记得有这样做过，也没有报错呀，离大谱

刚开始以为是自己node.js环境变量没配置好，重新检查了一遍，少了这些配置然后重新下载依赖包，发现还是不行，网上解决方案挺多，但总有不适合自己项目的

使用npm cache verify清除npm缓存重新下载依赖包，依旧报错

清除缓存：

Cache verified and compressed (C:\Program Files\nodejs\node_cache\_cacache):

Content verified: 4661 (496839341 bytes)

Index entries: 7125

Finished in 4.26s

接着再试试别的方法，找到了一个播客是下载的时候后面加上了淘宝镜像

命令：npm install --registry=https://registry.npm.taobao.org

注意：每次试之前把失败的node_modules和package-lock.json文件删掉，不然还是会报错的

完美解决，虽然不知道前面的检查有没有影响，但好歹项目可以正常运行，node_moudels文件也没有那么大了，恢复到了几百兆
