ModuleNotFoundError: No module named ‘flask._compat
使用flask_script管理flask启动
注意：
- 最后两个错有解决没有略过至于报错顺序
- 在解决完flask版本 Jinja2 有可能会报错 看自己的版本 最后一个Jinja2错误是复现出来的
代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | from flask import Flaskimport configfrom flask_script import Managerapp=Flask(__name__)#app.config.from_object(config.MyConfig)manager = Manager(app)if __name__ == '__main__': manager.run() |

from flask._compat import text_type
ModuleNotFoundError: No module named ‘flask._compat’
查看安装的包
1 | pip freeze |
发现安装的flask的版本过高没有 直接拉取的话就是最新版的
版本降低即可解决
1 | pip3 install flask==1.1.4 |
版本更新完
接着又报错
Traceback (most recent call last):

from markupsafe import soft_unicode
ImportError: cannot import name ‘soft_unicode’ from ‘markupsafe’
查看markupsafe版本发现是2.1.1
markupsafe版本降低
1 | python -m pip install markupsafe==2.0.1 |
来继续报错
Traceback (most recent call last):
File “test3.py”, line 1, in
from flask import Flask
File “/Users/tly/opt/anaconda3/envs/FlaskProject/lib/python3.8/site-packages/flask/__init__.py”, line 14, in
from jinja2 import escape
ImportError: cannot import name ‘escape’ from ‘jinja2’ (/Users/tly/opt/anaconda3/envs/FlaskProject/lib/python3.8/site-packages/jinja2/__init__.py)
继续降版本
1 | pip install Jinja2==3.0.0 |
到此为止输入命令python test3.py runserver项目启动起来
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持IT俱乐部。
