在create-react-app下使用es7的@修飾器會(huì)報(bào)錯(cuò)''Support for the experimental syntax 'decorators-legacy' isn't currently enable"
需要做以下幾步,首先正確安裝babel
"devDependencies": {
"@babel/core": "^7.1.6",
"@babel/plugin-proposal-class-properties": "^7.1.0",
"@babel/plugin-proposal-decorators": "^7.1.6",
"@babel/preset-env": "^7.1.6",
}
.babelrc文件配置:
{
"presets": ["@babel/preset-env"],
"plugins": [
["@babel/plugin-proposal-decorators", { "legacy": true }],
["@babel/plugin-proposal-class-properties", { "loose": true }]
]
}
在pageage.json同級(jí)目錄新建config-overrides.js并且添加內(nèi)容
const { injectBabelPlugin } = require('react-app-rewired');
module.exports = function override(config, env) {
// do stuff with the webpack config...
config = injectBabelPlugin(['@babel/plugin-proposal-decorators', { "legacy": true }], config) //{ "legacy": true }一定不能掉,否則報(bào)錯(cuò)
return config;
};
安裝react-app-rewired并且修改啟動(dòng)package.json
"scripts": {
- "start": "react-scripts start",
+ "start": "react-app-rewired start",
- "build": "react-scripts build",
+ "build": "react-app-rewired build",
- "test": "react-scripts test",
+ "test": "react-app-rewired test",
}
最后運(yùn)行即可解決
