我的反应有问题。其编译错误为:
编译失败
./node_modules/reactstrap/dist/reactstrap.es.js Attempted import error: 'react-lifecycles-compat' does not contain a default export (imported as 'reactLifecyclesCompat').
我具有以下依赖性
"dependencies": {
"bootstrap": "^4.1.1",
"react": "^16.7.0",
"react-dom": "^16.7.0",
"react-lifecycles-compat": "^3.0.4",
"react-scripts": "2.1.2",
"react-transition-group": "^2.5.2",
"reactstrap": "^7.0.0",
"uuid": "^3.3.2"
}
然后,我在位置“ src / components /”处创建了一个AppNavbar
组件,它只是一个简单的导航栏,下面是我的AppNavbar
组件代码,它在文件末尾导出。 / p>
import React, { Component } from 'react';
import {
Collapse,
Navbar,
NavbarToggler,
NavbarBrand,
Nav,
NavItem,
NavLink,
Container
} from 'reactstrap';
class AppNavbar extends Component {
state = {
isOpen: false
}
toggle = () => {
this.setState({
isOpen: !this.state.isOpen
})
}
render() {
return (
<div>
<Navbar color="dark" dark expand="sm" className="mb-5">
<Container>
<NavbarBrand href="/">Shopping List!</NavbarBrand>
<NavbarToggler onClick={this.toggle} />
<Collapse isOpen={this.state.isOpen} navbar>
<Nav className="ml-auto" navbar>
<NavItem>
<NavLink href="https://about.me">About</NavLink>
</NavItem>
</Nav>
</Collapse>
</Container>
</Navbar>
</div>
);
}
}
export default AppNavbar;
然后将其显示在页面上,我像这样将AppNavbar
导入App.js:
import React, { Component } from 'react';
import AppNavbar from './components/AppNavbar';
import 'bootstrap/dist/css/bootstrap.min.css';
import './App.css';
class App extends Component {
render() {
return (
<div className="App">
<AppNavbar />
</div>
);
}
}
export default App;
答案 0 :(得分:1)
这不是代码中的错误,而是通过reactstrap
导入所需的依赖项的方式。看看:https://github.com/reactstrap/reactstrap/issues/1343。
