我正在使用Material-UI在我的ReactJS项目中创建“材料标签”,此代码在SANDBOX中正常工作,但在我的VS代码中无法正常工作。我该怎么办?
我检查了要安装的节点,检查并安装了NPM中的所有依赖项版本。 我也检查了一下。 check it,但我听不懂。
import React from "react";
import PropTypes from "prop-types";
import SwipeableViews from "react-swipeable-views";
import { makeStyles } from "@material-ui/core/styles";
import { withStyles } from "@material-ui/styles";
import Tabs from "@material-ui/core/Tabs";
import Tab from "@material-ui/core/Tab";
import Typography from "@material-ui/core/Typography";
function TabContainer({ children, dir }) {
return (
<Typography component="div" dir={dir} style={{ padding: 8 * 3 }}>
{children}
</Typography>
);
}
const useStyles = makeStyles(theme => ({
root: {
backgroundColor: theme.palette.background.paper,
width: 500
}
}));
class Feature extends React.Component {
constructor(props) {
super(props);
this.state = { value: 0 };
}
handleChange() {
this.state.value === 0
? this.setState({ value: 1 })
: this.setState({ value: 0 });
}
render() {
const classes = this.props;
const theme = this.props;
return (
<div className={classes.root}>
<Tabs
value={this.state.value}
onChange={this.handleChange.bind(this)}
indicatorColor="primary"
textColor="primary"
>
<Tab label="A" />
<Tab label="B" />
</Tabs>
<SwipeableViews
axis={theme.direction === "rtl" ? "x-reverse" : "x"}
index={this.state.value}
>
<TabContainer dir={theme.direction}>Item One</TabContainer>
<TabContainer dir={theme.direction}>Item Two</TabContainer>
</SwipeableViews>
</div>
);
}
}
Feature.propTypes = {
classes: PropTypes.object.isRequired
};
export default withStyles(useStyles)(Feature);
我的 package.json 看起来像
"dependencies": {
"@material-ui/core": "^3.9.2",
"@material-ui/docs": "^3.0.0-alpha.9",
"@material-ui/styles": "^4.0.1",
"prop-types": "^15.7.2",
"react": "^16.8.5",
"react-dom": "^16.8.5",
"react-redux": "^6.0.1",
"react-router-dom": "^5.0.0",
"react-scripts": "2.1.8",
"react-slick": "^0.23.2",
"react-swipeable-views": "^0.13.3",
"redux": "^4.0.1",
"styled-components": "^4.2.0"
}
我希望得到SANDBOX给定的输出,但是却出现了此错误
TypeError: Object(...) is not a function
const useStyles = makeStyles(theme => ({
root: {
backgroundColor: theme.palette.background.paper,
width: 500
}
}));
在上面的代码中。
答案 0 :(得分:0)
在沙箱中,您使用的是@material-ui/core latest
版本(当前为4.0.1
),在VS Code package.json中,您使用的是版本3.9.2
。我很确定这就是问题所在,请尝试使用完全相同的版本,而不要使用latest
。
