重装 node_modules 不管用

重装 node 不管用



node 版本问题,node v10 以上 fs.write 的callback 是必须的,降低Node版本可解决。
将webpack.dev.config.js 和 webpack.prod.config.js 中的代码修改即可:给fs.write添加必要的callback函数。


更改 webpack.dev.config.js

fs.open('./build/env.js', 'w', function (err, fd) {
    const buf = 'export default "development";';
    fs.write(fd, buf, 0, 'utf-8', function(err, written, buffer) {});
    // fs.write(fd, buf, 0, buf.length, 0, function (err, written, buffer) {
    // });
