Q:

> gulp

fs.js:35
} = primordials;
    ^

ReferenceError: primordials is not defined

场景：npm run build 时候报错

  ```

node -v v12.18.2 npm -v 6.14.5 gulp -v CLI version: 2.3.0 Local version: Unknown or 3.9.1 

  ```

  ```

分析/原因： node 版本和gulp版本不一致导致的。 node12及以上对应gulp4及以上。

解决方案：

​ 方案一：降低node版本。

  • 下载旧版本node

  • 注意环境变量的切换配置

    linux 上可用 n模块。来源于npm 安装n模块。

    root@iz2ze56pkpg6dxap2z3qvzz ~]# npm i -g n
/usr/local/bin/n -> /usr/local/lib/node_modules/n/bin/n
+ n@6.5.1
added 1 package from 4 contributors in 1.492s

 切换node版本

​

​ 方案二：提升gulp版本到4。注意：gulp4后的语法有所改变。gulpfile.js要改

A:

  • 删除 node_modules rm -rf node_modules

  • 用淘宝源重新安装

    npm install chromedriver --chromedriver_cdnurl=http://cdn.npm.taobao.org/dist/chromedriver
