Question

有人可以帮我吗？这是我每次运行npm run group

时遇到的错误

assert.js：374 抛出错误 ^

我是Npm和Javscript领域的初学者，所以请您解释一下其背后的所有错误和原因，对我会有很大帮助。

Answer 1

首先不需要run-sequence。

更改此：

gulp.task('group', [   // this is gulp3 syntax, you are using gulp4 presumably
  'groupChrome',
  'groupSafari',
  'groupWebext'
]);


gulp.task('test', gulpSequence('prepareTest', 'eslint', 'karma'));

到

gulp.task('group', gulp.series(   // here was your main problem
  'groupChrome',
  'groupSafari',
  'groupWebext'
));


gulp.task('test', gulp.series('prepareTest', 'eslint', 'karma'));

所以gulp v3使用gulp.task('someTaskName', ['taskA', 'taskB', etc.])

gulp v4使用gulp.task('someTaskName', gulp.series('taskA', 'taskB', etc.))

搜索从v3到v4的gulp迁移指南，以了解更多信息。

我在运行命令`npm run group`
