Vue-CLI3.x 自动部署项目至服务器的方法步骤

 */

const envfile = process.env.NODE_ENV === 'prod' ? '../.env.prod' : '../.env.dev';
// env环境变量的路径
const envPath = path.resolve(__dirname, envfile);
// env对象
const envObj = parse(fs.readFileSync(envPath, 'utf8'));
const SERVER_ID = parseInt(envObj['VUE_APP_SERVER_ID']);

function parse(src) {
  // 解析KEY=VAL的文件
  const res = {};

    // matching "KEY' and 'VAL' in 'KEY=VAL'
    // eslint-disable-next-line no-useless-escape

      }

      // remove any surrounding quotes and extra spaces
