问题是我的应用程序无法在IE11中正常工作，我正在将vue-cli3与babel polyfill 7一起使用（package.json中的浏览器列表）
在IE11上，我在控制台expected ':'
当我尝试命令npx browserSlist时，我看到IE11，这样就可以了：）
我的babel.conf ：（我将默认的@vue ...预设更改为@ babel / preset-env，因此debug：true有效）
module.exports = {
'presets': [
[
'@babel/preset-env',
{
'useBuiltIns': 'entry'
},
],
],
};
package.json中的浏览器列表部分：
"browserslist": [
"last 1 version",
"> 1%",
"not dead",
"ie 11"
]

答案 0 :(得分：0)
问题是与es2015不兼容的插件。 之前（可能是在vue cli2中）可能已经将webpack配置为可移植所有node_modules，但这不一定是普遍做法。
在此博客中，您可以了解如何将es6代码发布到npm
