请帮助我。提前致谢
【问题讨论】：
-
请注意，在 ubuntu 机器上，
pip默认指的是 python27 的 pip 版本（感谢PEP394）。如果您已开发此应用程序以在 python3 上运行，那么您应该使用pip3 install flask-jwt-extended，为此您必须首先使用sudo apt install python3-pip。 -
当我输入 pip3 install flask-jwt-extended 时，终端返回已经满足要求。
-
您使用的是虚拟环境吗？如果是这样，您是否将 uwsgi 配置为使用该 python 实例而不是系统实例？
-
@vimalloc 我已经配置了我的 uwgi。我不知道当涉及到它时有什么问题。在虚拟环境中，脚本运行良好，没有错误。您知道为什么 uwgsi 无法读取 flask-jwt-extended 吗？
-
你有没有设置你的uwsgi来使用通风口，你运行的是什么版本的uwsgi。我非常怀疑这是问题所在。
