我最近升级到了 webpack 5.65.0。这打破了@react-pdf/renderer。 GitHub 问题上的 answer 具有我正在尝试实施的修复程序。尝试“修复”后,我得到了与此 SO Question 完全相同的错误,但该解决方案不适用于我。

我已经多次指手画脚了,但我在这里找不到。我刚刚添加的相关代码在module.exports&gt;resolve&gt;fallbackmodule.exports&gt;resolve&gt;plugins 中。任何提示或帮助将不胜感激。

【问题讨论】:

这是一个大代码块! 【参考方案1】:
const  WebpackManifestPlugin  = require('webpack-manifest-plugin');

我认为这种代码和平是错误的

because  WebpackManifestPlugin  is undefined
