Question

const Button = ({ title, count, onClick }) => {
  console.log(`Rendering ${title}`)
  return (
    <button onClick={onClick}>
      {title} ({count})
    </button>
  )
}
const Header = () => {
  console.log("Rendering Title")
  return <h1>App Title</h1>
}

const Parent = () => {
  const [add, setAdd] = React.useState(0)
  const [edit, setEdit] = React.useState(0)
  const [remove, setRemove] = React.useState(0)
  
  const handleAdd = () => setAdd(add + 1)
  const handleEdit = () => setEdit(edit + 1)
  const handleRemove = React.useCallback(() => {
    setRemove(remove + 1)
  }, [remove])

  return (
    <React.Fragment>
      <Header />
      <Button title="Add" onClick={handleAdd} count={add} />
      <Button title="Edit" onClick={handleEdit} count={edit} />
      <Button title="Remove" onClick={handleRemove} count={remove} />
    </React.Fragment>
  )
}

function App() {
  return (
    <div className="App">
      <Parent />
      <button onClick={console.clear}>Clear log</button>
    </div>
  )
}

ReactDOM.render( <App /> , document.getElementById('root'))

然后我得到文件“ C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site- packages \ tensorflow__init __。py“，第24行，在从tensorflow.python import pywrap_tensorflow＃pylint：disable = unused-import 文件“ C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site- packages \ tensorflow \ python__init __。py“，第49行，在从tensorflow.python导入pywrap_tensorflow 文件“ C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site- packages \ tensorflow \ python \ pywrap_tensorflow.py”，第74行，在提高ImportError（msg） ImportError：回溯（最近一次调用最近）：文件“ C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site- packages \ tensorflow \ python \ pywrap_tensorflow.py”，第58行，在从tensorflow.python.pywrap_tensorflow_internal导入* 文件“ C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site- packages \ tensorflow \ python \ pywrap_tensorflow_internal.py”，第28行，在 _pywrap_tensorflow_internal = swig_import_helper（）文件“ C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site- packages \ tensorflow \ python \ pywrap_tensorflow_internal.py”，第24行，在swig_import_helper中 _mod = imp.load_module（'_ pywrap_tensorflow_internal'，fp，路径名，描述）文件“ C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ imp.py”，第242行，在 load_module 返回load_dynamic（名称，文件名，文件）文件“ C：\ Users \ Administrator \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ imp.py”，第342行，在 load_dynamic 返回_load（spec） ImportError：DLL加载失败：动态链接库（DLL）初始化例程失败。
