BrowserslistError：未知的浏览器kaios

Question

我已经更新了项目以使用node和yarn的最新版本，此升级之后，我的react项目不再希望与“ browserslist”一起使用。

我运行“纱线启动”并得到此错误：

./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
• 纱线v1.15.2

而我的package.json

{
  "name": "frontend",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@material-ui/core": "3.9.3",
    "@material-ui/icons": "3.0.2",
    "axios": "0.18.0",

    "react-swipeable-views": "0.13.1",
    "redux": "4.0.1",
    "redux-immutable": "4.0.0",
    "redux-persist": "5.10.0",
    "redux-thunk": "2.3.0",
    "weather-icons": "^1.3.2"
  },
  "scripts": {
    "start": "react-scripts --max-old-space-size=8192 start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "browserslist": [
    ">1%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

对我来说，这个问题与css-loader有关，我尝试解决此问题，然后将css-loader@2.1.1添加到package.json中。我尝试使用其他解决方案，但没有一个可行。

Answer 1

TL; DR rm yarn.lock; yarn

长篇散文：

双方browserslist并postcss-preset-env可能是第二级（深）的依赖。这在中很常见create-react-app。但是，yarn upgrade这不会升级锁定的子依赖关系，并且这样做会违反纱线的原理。

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来解析良好的版本。如果是这样，那yarn是正确的。

通过建立项目的某些{browserslist, caniuse-lite, postcss-preset-env}直接[dev]依赖关系，可以解决此问题。

或更短一点rm yarn.lock; yarn？

Answer 2

我面临着同样的问题，并通过版本固定caniuse-lite在package.json与之前的最后一个版本，我是能够解决该问题。

附加到 package.json

  "resolutions": {
    "caniuse-lite": "1.0.30000957"
  },

跑 $ yarn

并检查yarn.lock是否使用了预期的版本：

...
caniuse-lite@1.0.30000957, caniuse-lite@^1.0.0, caniuse-lite@^1.0.30000939, caniuse-lite@^1.0.30000955, caniuse-lite@^1.0.30000957:
  version "1.0.30000957"
  resolved "https://registry.yarnpkg.com/caniuse-lite/-/caniuse-lite-1.0.30000957.tgz#fb1026bf184d7d62c685205358c3b24b9e29f7b3"
