" P7 a% F0 z2 \7 x3 Q6 [2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org

4、关键所在！！！执行编译时指定python版本，npm install --python=python2.7
& f; v# w1 G, o' }1 c5 l/ A6 d" I
1 s- n' x3 M8 V, [由于我的电脑之前安装过python3版本，并且设置了环境变量，所以npm install会找我默认的python,所以执行时指定nodejs只支持的python2版本。

然后，神奇的事情到了，我把编译包modules删掉后重新编译(这次不指定python2版本直接npm install)，居然奇迹般的又没有报错！！！想不通。。。难道npm会将上次编译成功的配置保存下来？？算了不纠结了哭泣！
