当我尝试打开构建项目时收到此错误
顺便说一句,该项目在开发模式下运行良好。
Uncaught TypeError: Cannot read property 'hasOwnProperty' of undefined
at Object.<anonymous> (react-dom.production.min.js:760)
at m (bundle.js:1)
at Object.<anonymous> (index.js:34)
at m (bundle.js:1)

生成错误的第 760 行。 注意变量aa是require("react");
var Tb = aa.__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED;
Tb.hasOwnProperty("ReactCurrentDispatcher") || (Tb.ReactCurrentDispatcher = {
current: null
});
这是我的 package.json,你注意到我使用了最新版本的 React 和 React-Dom
{
"name": "xxxx",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^16.8.6",
"react-confirm-alert": "^2.4.1",
"react-dom": "^16.8.6",
"react-redux": "^7.0.2",
"react-router-dom": "^5.0.0",
"react-scripts": "2.1.8",
"redux": "^4.0.1"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"eslintConfig": {
"extends": "react-app"
},
"browserslist": [
">0.2%",
"not dead",
"not ie <= 11",
"not op_mini all"
],
"proxy": "http://localhost:3001",
"devDependencies": {
"datatables.net": "^1.10.19",
"jquery": "^3.4.0"
}
}
构建生成的index.html
最佳答案
我遇到了这个问题,并花了两个小时浏览网页。
然后我做了一个npm list | grep react
并意识到 react
和 react-dom
有不同的版本。 package.json
仅指定版本范围,但不保证它们在同一版本上运行。
所以我所做的是npm rm React React-dom && npm i -s React React-dom
。
现在他们有了相同的版本,终于可以一起工作了。
