我正在经历一个TypeError
我不确定如何解决它。我期待您能提供的任何帮助。以下是终端输出yarn run build
:
BUILD_DIR /Users/blakelucey/Desktop/fsd-next/build

这是webpack.config.js

我想我需要删除这里的评论:
// const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
和这里:
// optimization: {
// minimizer: [
// new UglifyJsPlugin({sourceMap: true})
// ]
// },
但我不确定。我期待并感谢您贡献的任何意见,谢谢。
