项目要用到node-gyp(给爷爬)

mac上没问题 windows有问题

看上面的日志, 提到了 python2.7

看来这个模块用的上古时代的python2.7的技术

windows的同学可以先安装 python2 这里下载:  https://www.python.org/ftp/python/2.7/python-2.7.amd64.msi

不要修改路径!! 不要修改路径!! 等他安装到 C:\python2.7\ 目录下面哈. 这样不会影响你的 python3+体系

安装了python再执行  npm config set python python2.7 表示npm中凡是遇到python命令统一修正为执行python2.7

再执行 npm install node-gyp 就好了, 是不是很顺利哇?

以后如又有其他的包用的python3遇到报错的话那么可以使用 npm config delete python 这样恢复npm命令的python版本环境变量( npm config list 查看)

------------------------

win10了解WSL的同学完全可以切换到WSL里面编码哈,支持热更新.什么node-gyp上面这些问题都不会遇到.  WSL2还没试过(因为WSL用着挺顺手)

----------------------

总结:

1. 默认安装python2.7
2. 映射npm config set pytyon python2.7
