升级到Mix v4.x后,对linkList = ['https://www.link1.com', 'https://www.link2.com'];
adsList = []
let ads = async () => {
const req = axios(apiUrl + linkList)
const res = await Promise.resolve(req)
adLinks.push(res.data.shortenedUrl)
console.log(adsList)
// Here, it shows a updated array everytime a promise is resolved
}
ads()
console.log(adsList) // Returns [], because the promises aren't resolved by the time it runs
的任何调用都会导致不确定混合。我每次运行都会看到这样的错误:
adsList
我正在使用Laravel 5.5运行它。我升级了npm run
,以使其与Mix v4一起使用的laravel存储库中的版本相匹配。
这是我的> npm run development

我尝试再次删除webpack.mix.js
和const { mix } = require('laravel-mix');
mix.js('resources/assets/js/app.js', 'public/js')
.sass('resources/assets/sass/app.scss', 'public/css')
.version()
.sourceMaps();
,但这不能解决问题。
如果我降级到v3,除了编译一些SASS的问题之外没有其他问题。

没有看到您的webpack.mix.js
文件,很难说出问题所在。我克隆了Laravel 5.5分支,并升级到^4.0.13
的版本laravel-mix
,并成功运行了yarn dev
和yarn prod
,尽管我使用的是npm和node的最新版本。 / p>
这里是GitHub repo演示对象。
更新
// TypeError: Cannot read property 'js' of undefined
const { mix } = require('laravel-mix');
// works
const mix = require('laravel-mix');
答案 1 :(得分:0)
当我这样更改webpack.mix.js文件时:
// TypeError:无法读取未定义的属性'js'
const {mix} = require('laravel-mix');
//工作
const mix = require('laravel-mix');
然后它对我有用!
