解决webpack打包报错 [webpack-cli] TypeError: merge is not a function问题

报错信息如下：

[webpack-cli] Failed to load '/Users/allard/Desktop/webpack-react-scaffold/config/webpack.prod.config.js' config
[webpack-cli] TypeError: merge is not a function
npm ERR! Failed at the webpack-react-scaffold@1.0.0 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

报错意思： TypeError: merge 不是一个函数。

查看配置文件中设置为：const merge = require('webpack-merge');

查看官网上的介绍后修改为：const {merge} = require('webpack-merge');

配置文件修改成上面后，再次打包通过。

注：

1. 从 webpack-merge5.0.3 及更高版本开始，则需要使用：const {merge} = require('webpack-merge');
2. 如果版本低于 5.0.3，则需要使用：const merge = require('webpack-merge');
