安装慢的原因
% f- n# t, L9 r  h3 jnpm install 默认使用的安装镜像是国外的镜像，😒😒
所以在国内使用，会受到网络的限制，所以导致安装速度及其之慢，有的时候，会因为网速问题直接报错

- K8 _2 P) s& T/ ]解决方式
方式一：更换npm的安装镜像源为国内的即可改变
方式二：更换网络（一般不会这么做）

【更换npm源】：

npm config set registry https://registry.npm.taobao.org

如果没有报错就是已经切换成功，然后我们再次执行 npm install

* r( Y" Z! {1 R' z& X3 d2 @; s$ O4 c7 j3 ~0 p

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

yarn安装依赖速度太慢的解决办法

1、在用户目录文件夹下找到.yarnc文件（如我的是在：C:\Users\钟志胜\下）

% V; h9 c: H% `7 C) q+ r2、编辑.yarnc文件，添加如下内容

registry "https://registry.npm.taobao.org"
