這篇文章主要介紹了解決ModuleNotFoundError: No module named ‘flask._compat的問題,具有很好的參考價(jià)值,希望對(duì)大家有所幫助,如有錯(cuò)誤或未考慮完全的地方,望不吝賜教

ModuleNotFoundError: No module named ‘flask._compat

使用flask_script管理flask啟動(dòng)

注意：

最后兩個(gè)錯(cuò)有解決沒有略過至于報(bào)錯(cuò)順序
在解決完flask版本 Jinja2 有可能會(huì)報(bào)錯(cuò) 看自己的版本最后一個(gè)Jinja2錯(cuò)誤是復(fù)現(xiàn)出來(lái)的

代碼：

from flask import Flask
import config
from flask_script import Manager

app=Flask(__name__)

#app.config.from_object(config.MyConfig)

manager = Manager(app)



if __name__ == '__main__':
    manager.run()

報(bào)錯(cuò)信息

from flask._compat import text_type
ModuleNotFoundError: No module named 'flask._compat'

查看安裝的包

pip  freeze

發(fā)現(xiàn)安裝的flask的版本過高沒有直接拉取的話就是最新版的

版本降低即可解決

pip3 install flask==1.1.4

版本更新完

接著又報(bào)錯(cuò)

查看markupsafe版本發(fā)現(xiàn)是2.1.1

markupsafe版本降低

python -m pip install markupsafe==2.0.1

來(lái)繼續(xù)報(bào)錯(cuò)
