我已经更新了我的项目以使用最新版本的节点和 yarn ，在这次升级之后，我的 react 项目不想使用“browserslist”。
我运行“yarn start”并收到此错误:
./src/assets/css/material-dashboard-react.css?v=1.2.0 (./node_modules/css-loader??ref--6-oneOf-3-1!./node_modules/postcss-loader/src??postcss!./src/assets/css/material-dashboard-react.css?v=1.2.0)
BrowserslistError: Unknown browser kaios
at Array.reduce (<anonymous>)
at Array.some (<anonymous>)
at Array.filter (<anonymous>)
at new Promise (<anonymous>)
我有以下版本:
- 节点 v10.15.3
- npm 6.9.0
- yarn v1.15.2
我的 package.json 是它

对我来说，这个问题与 css-loader 有关，我尝试解决该问题并将 css-loader@2.1.1 添加到 package.json 中。我尝试使用其他解决方案，但没有一个有效。
最佳答案
TL;DR rm yarn .lock; yarn
长篇散文:
browserslist 和 postcss-preset-env 都可能是二级(深层)依赖项。这在 create-react-app 中很常见。但是，yarn Upgrade 不会升级锁定的子依赖项，并且执行此操作的命令违反了yarn 的哲学。
可以说，这些库之一应该限制所需的依赖版本，并将其留给 yarn 来解析好的版本。如果是这样，那么 yarn 是正确的。
可以通过为项目创建一些{browserslist, caniuse-lite, postcss-preset-env}直接[dev]依赖项来解决此问题。
或者更短，rm yarn.lock; yarn ✨
