class App extends React.Component {

  constructor(props) {
    super(props);
    this.state = {
      drawerOpen : false
    };

    this.handleDrawerOpen = this.handleDrawerOpen.bind(this);
    this.handleDrawerClosed = this.handleDrawerClosed.bind(this);
  }


  handleDrawerOpen() {
    this.setState({drawerOpen : true});
    console.log("open");
  }

  handleDrawerClosed() {
    this.setState({drawerOpen : false});
    console.log("close");
  }

  render() {
    return (

        <Drawer
          variant="persistent"
          anchor="left"
          open={this.state.drawerOpen}
        >
          <div onClick={this.handleDrawerClose}>
            <IconButton onClick={this.handleDrawerClose}>
              <ChevronLeftIcon />
            </IconButton>
          </div>
          <Divider />
          <List>
            {['Home', 'Categories'].map((text, index) => (
              <ListItem button key={text}>
                <ListItemIcon>{index === 0 ? <HomeIcon /> : <MailIcon />}</ListItemIcon>
                <ListItemText primary={text} />
              </ListItem>
            ))}
          </List>
        </Drawer>

      </div>
    );
  }

}

出什么问题了？我确实从https://material-ui.com/components/drawers/

您的处理程序称为handleDrawerClosed，但您正在调用handleDrawerClose（末尾没有'd'）。

更新您的处理程序以匹配打开的处理程序，然后将其重命名为handleDrawerClose

此外，使用IDE可以自动为您突出显示此类问题，并节省时间和沮丧：-D
