安装慢的原因
+ O, P; W1 p3 C4 M& |npm 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

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）

2 d3 @8 o& h4 Z& E# S【更换npm源】：

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

1 i; j7 Z6 m4 `% ?# e如果没有报错就是已经切换成功，然后我们再次执行 npm install
或者我们可以在安装的时候指定其安装镜像

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

7. 如果返回值不为null，继续执行：

8. （这一步很重要，一定要保证两个命令的返回值都为null,话说回来，应该出现这个错误这两个返回值有不为null的）
   % R4 I8 m  }; j6 P
9. npm config set proxy null
