1、卸载nodejs重新安装一遍

% o" M1 V) J( y% u8 y* D2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org

3、安装nodejs所需的环境（Visual Studio XX、python什么鬼的）,执行这个命令会自动检测并帮你安装好，npm install --g --production windows-build-tools

4、关键所在！！！执行编译时指定python版本，npm install --python=python2.7
7 w: O! q/ C- o  p0 ~- O
- J1 ?* _! A7 y) p' p6 p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。
' A, F  g/ U5 g: e! R( F
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！
