Reactjs React MaterialUI:createSvgIcon不是一个函数

我正在尝试使用MaterialUI的自动完成组件进行React。在编辑器中，一切看起来都很好，编译也很好。但是，我得到以下运行时错误：

app.js:42207 Uncaught TypeError: (0 , _utils.createSvgIcon) is not a function
    at Object.393.@babel/runtime/helpers/interopRequireWildcard (app.js:42207)
    at o (app.js:6)
    at app.js:6
    at Object.<anonymous> (app.js:41216)

您可能安装了错误版本的

@material ui/icons

尝试删除

package lock.json

和

node\u modules

文件夹，然后再次运行

npm install

  import TextField from '@material-ui/core/TextField';
  import Autocomplete from '@material-ui/lab/Autocomplete';
  ...

  <Autocomplete
    id="edit-var"
    freeSolo
    options={props.existing}
    renderInput={params => (
      <TextField
        {...params}
        label="Variable"
        margin="normal"
        variant="outlined"
        value={props.variable.name}
        autoFocus={true}
        onChange={e => props.onUpdate({ ...props.variable, name: e.currentTarget.value })}
      />
    )}
  />

    "@material-ui/icons": "^4.9.1",
