npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

原因：

print "%s.%s.%s" % sys.version_info[:3];

为python2.x版本的语法，如果本地安装的是python3.x，就会报此错误

解决⽅法：

1. 删除项⽬中的package-lock.json⽂件，清除缓存，更新版本号

#后续步骤运⾏npm install 命令时会重新⽣成package-lock.json⽂件

rm ./package-lock.json （如果windows系统，⼿动删除即可）

# linux 或windows cmd命令窗⼝下：

npm cache clear --force

npm install -g npm

2. 修改package-lock.json中依赖包的版本号

"node-sass": "4.14.1",

"npm": "^6.14.5",

#sass-loader版本为可选项，如果项⽬很旧，sass-loader版本最好不要改动，否则容易引起项⽬启动异常

"sass-loader": "8.0.2",

npm 版本号： npm -v 命令获取

3 重新运⾏ npm install 命令，即可成功
