关于NPM post install的下载速度提升

最近在使用prisma gnerate client代码的时候突然发现网络错误无法下载binary文件

我记得我第一次开发electron的时候被electron postintall搞的头都大了，真的太慢了。

那时候刚刚做前端的时候，随着后面越来越多的库都有依赖post install下载binary

直到某一天我发现了Anthony Fu一篇踩坑记录NPM Binary 镜像配置，我才幡然醒悟，为什么npm，docker都有镜像，为什么这个binary没有镜像呢？

所有的主流post install都可以像如下配置在你的.bashrc类似的shell暴露环境变量

比如要配置的prima generate client的时候

可以像这样

PRISMA_ENGINES_MIRROR=https://cdn.npmmirror.com/binaries/prisma

也有electron可以有这种特殊配置在.npmrc

electron_mirror=https://npmmirror.com/mirrors/electron/

当然还有更多的binary镜像，你可以在github.com/cnpm/binary… 找到更多的镜像配置
