英文:
webpack v5 configuration error: fallback parameter does not match the schema
问题
webpack v5的webpack partial配置出错，错误信息显示fallback属性不被识别。日志内容指出未处理的异常，配置对象与API模式不匹配。这里的文档明确表示fallback属性已包含。
英文:
what is wrong with my webpack-partial config in webpack v5? I have no clue why I'm getting an error about the fallback parameter when the docs explicitly say it is included here. All my logs when the webpack partial is loaded say I am using webpack 5.82.1

我遵循了webpack的错误消息（尽管它们与文档不匹配），最终得到了一个可用的配置。以下是我必须更改的内容：
module.exports = {
resolve: {
//modules: [...],
resolver:{
fallback: {
"fs": false,
……
请注意，resolve有一个名为resolver的子属性，其中包含了回退项。
英文:
I followed the webpack error messages (despite them not matching the docs) and I wound up with a working config. Here is what I had to change:
module.exports = {
resolve: {
//modules: [...],
resolver:{
fallback: {
"fs": false,
......
Note that resolve has a child of resolver which contains the fallbacks
