flask中遇到ImportError: cannot import name ‘url_encode‘ from ‘werkzeug‘

Traceback (most recent call last): File "book_management_sys.py", line 5, in <module> from forms import Login, SearchBookForm, ChangePasswordForm, EditInfoForm, SearchStudentForm, NewStoreForm, StoreForm, BorrowForm File "C:\pythonProject\pythonProject2\Flask-Book-Management\forms.py", line 1, in <module> from flask_wtf import FlaskForm File "C:\pythonProject\pythonProject2\venv\lib\site-packages\flask_wtf\__init__.py", line 17, in <module> from .recaptcha import * File "C:\pythonProject\pythonProject2\venv\lib\site-packages\flask_wtf\recaptcha\__init__.py", line 2, in <module> from .fields import * File "C:\pythonProject\pythonProject2\venv\lib\site-packages\flask_wtf\recaptcha\fields.py", line 3, in <module> from . import widgets File "C:\pythonProject\pythonProject2\venv\lib\site-packages\flask_wtf\recaptcha\widgets.py", line 5, in <module> from werkzeug import url_encode ImportError: cannot import name 'url_encode' from 'werkzeug' (C:\pythonProject\pythonProject2\venv\lib\site-packages\werkzeug\__init__.py)

我们需要把werkzeug中的版本换成pip install werkzeug==0.16.1这个
