jQuery不能使用,我无法使用bootstrap下拉菜单、自定义JavaScript等。
在运行npm run dev
或npm run build
之后,app.js
文件已经成功创建并在浏览器中加载。
编译过程没有出现任何错误。
我尝试启用.autoProvidejQuery()
然后运行npm run dev
/ npm run build
,但没有任何改变。
我正在使用Symfony 4.1.6.
解决方法
在webpack.config.js中将.enableSingleRuntimeChunk()改为.disableSingleRuntimeChunk()
如果你只是注释掉这一行,它能够工作,但是当你运行npm run dev
或npm run build
时会有一个警告信息。

.addEntry('js/app', './assets/js/app.js')
更改为.addEntry('app', './assets/js/app.js')
