我正在使用CRA 2.0,并且想要弹出以便可以操纵配置。弹出后,我遇到了编译错误的问题:
./src/web-app-commons/HOC/OverlayWrapper.jsx
SyntaxError: /Users/prabhjotrai/temp/client-web/src/web-app-commons/HOC/OverlayWrapper.jsx: Support for the experimental syntax 'classProperties' isn't currently enabled (33:22):

34 | overlayProps: PropTypes.shape({
35 | open: PropTypes.bool
36 | })
Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation.
我已经尝试了与添加此插件有关的所有事情(包括将@babel/plugin-proposal-class-properties
作为dev依赖项添加并在babel配置中引用它),并且我认为它与https://github.com/babel/babel/issues/8648有关。但是,当我删除此特定文件时,下一个错误是:
./src/web-app-commons/HOC/Preview.jsx
SyntaxError: /Users/prabhjotrai/temp/client-web/src/web-app-commons/HOC/Preview.jsx: Support for the experimental syntax 'objectRestSpread' isn't currently enabled (60:3):

Add @babel/plugin-proposal-object-rest-spread (https://git.io/vb4Ss) to the 'plugins' section of your Babel config to enable transformation.
我的直觉是,这与高阶组件有关,因为我在代码中的其他任何地方都没有遇到此“ spread”错误或类属性声明错误。知道可能出什么问题了吗?
这是我的babel依赖项:
~/temp/client-web master ● cat package.json | grep babel
"@babel/core": "7.1.0",
"babel-core": "7.0.0-bridge.0",
"babel-eslint": "9.0.0",
"babel-jest": "23.6.0",
"babel-loader": "8.0.4",
"babel-plugin-emotion": "^9.2.5",
"babel-plugin-named-asset-import": "^0.2.2",
"babel-preset-react-app": "^5.0.4",
"@babel/plugin-proposal-class-properties": "^7.1.0",
"babel-plugin-glamorous-to-emotion": "^1.0.1",
"^.+\\.(js|jsx)$": "<rootDir>/node_modules/babel-jest",
"babel": {
"plugins": ["@babel/plugin-proposal-class-properties"]
任何帮助将不胜感激。
编辑
我添加了一个babelrc文件(从package.json中删除了配置),其中包含以下详细信息,但是没有运气:
{
"presets": [
"@babel/preset-env",
"@babel/preset-react",
"react-app"
],
"plugins": [
"@babel/plugin-proposal-class-properties",
"@babel/plugin-proposal-object-rest-spread"
]
}
答案 0 :(得分:-1)
Object spread仍然是建议,因此默认情况下在Babel中不可用。
只需将@ babel / plugin-proposal-object-rest-spread添加到像他们所说的插件中
