Geeks, please accept the hero post of 2021 Microsoft x Intel hacking contest>>>

Today, when using webpack to package projects, we encounter such a problem: couldn’t find press “es2015” relative to directory

The reasons for this problem are as follows:

The project does not use es standard, but the introduced Vue ueditor uses es standard, so the compilation error is reported

Solution:

cnpm install babel-preset-es2015 --save-dev

We recommend using Babel preset env now: please read Babel js.io/env to update

Reason: Babel has abandoned babel-preset-es2015, and now babel-preset-env is the latest one

Solution:

It can be solved by re installing Babel preset env

cnpm install babel-preset-env --save

Return to the first problem, not solved, ha ha ha

To add the following code to the webpack.base.conf.js file

module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'babel',
                query: {
                    presets: ['es2015']
                }
            }
        ]
    }
