運行 Simple Flask 程序時出現文件錯誤

Question

Traceback (most recent call last):

  File "<ipython-input-6-5b3985f98f53>", line 1, in <module>
    runfile('D:/document/VIT/Internship/IBM Externship/Notebooks/flask/first.py', wdir='D:/document/VIT/Internship/IBM Externship/Notebooks/flask')

  File "D:\Anaconda\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 827, in runfile
    execfile(filename, namespace)

  File "D:\Anaconda\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 110, in execfile
    exec(compile(f.read(), filename, 'exec'), namespace)

  File "D:/document/VIT/Internship/IBM Externship/Notebooks/flask/first.py", line 3, in <module>
    from flask import Flask

  File "D:\Anaconda\lib\site-packages\flask\__init__.py", line 21, in <module>
    from .app import Flask

  File "D:\Anaconda\lib\site-packages\flask\app.py", line 32, in <module>
    from werkzeug.wrappers import BaseResponse

ImportError: cannot import name 'BaseResponse' from 'werkzeug.wrappers' (D:\Anaconda\lib\site-packages\werkzeug\wrappers\__init__.py)

這是我得到的錯誤。 我對 Flask 很陌生，並試圖運行程序，如下所示：

from flask import Flask
app= Flask(__name__)

@app.route('/')
 
def index():
    return "Henlooo"
if __name__=='__main__':
    app.run(debug=False) 

請告訴我我需要在列出的文件中更改什么

試試這個：使用python -m pip uninstall werkzeug ，然后運行python -m pip install werkzeug如果您的項目需要特定版本運行python -m pip install werkzeug==2.0.3記得將版本更改為您的版本。
