Vue2 模板编译器坏了？

Question

我通过 webpack(^5.51.1) 和 vue-loader(^17.0.0) 编译我的代码，我尝试启动一个旧项目，但它给了我这个错误：

[webpack-cli] Failed to load '/var/www/webpack.config.js' config
[webpack-cli] Error: Cannot find module 'vue/compiler-sfc'
Require stack:
- /var/www/node_modules/vue-loader/dist/resolveScript.js

    '/var/www/node_modules/webpack-cli/bin/cli.js',
    '/var/www/node_modules/webpack/bin/webpack.js'
  ]
}

我真的不知道发生了什么。我尝试将 @vue/compiler-sfc 添加到我的 package.json 但它不起作用。我真的不想切换到 Vue3，因为那会破坏很多东西。

编辑：参见 package.json:pastebin
