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
node-sass 版本号:https://www.npmjs.com/package/node-sa #用比较新的版本
sass-loader 版本号:sass-loader - npm #用比较新的版本
3 重新运行 npm install 命令,即可成功
