python - Flask 不会在 PythonAnywhere 中使用我已安装的模块

问题描述

我需要帮助了解这里出了什么问题。

我会尽力解释这一点，但我对 PythonAnywhere 有点陌生。我收到此错误：

Traceback (most recent call last):
  File "/home/HelliottChip/mysite/app/__init__.py", line 6, in <module>
    from flask_migrate import Migrate
ModuleNotFoundError: No module named 'flask_migrate'

尝试运行我的 main.py 文件时。但是我已经安装了它们，如下代码所示：

17:14 ~/.local/bin $ pip install Flask-SQLAlchemy email_validator flask-mail pyjwt flask-bootstrap flask-moment                                                                                                  
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2
.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

我已经浏览了所有可以找到的有关如何解决此问题的网站，但我迷路了。这是我在 Replit.com 上工作了一段时间的 Flask 应用程序，它运行良好，直到转移到 PythonAnywhere。我已经尝试了大约两个星期来解决这个问题^~^但仍然没有运气。我使用了很多本指南来帮助我，因为我也在练习我的 Web 部署技能。（不需要判断我正在使用烧瓶-3-）但是有人可以花时间帮助我吗？如果可以的话，非常感谢。

解决方案

检查您在 PythonAnywhere 上的 Web 应用程序是否设置为由 Python 2.7 运行——我看到您在pip install虚拟环境之外使用，默认情况下它将使用 Python 2.7 的 pip，正如您在输出中看到的那样（顺便说一句。它赢了'不适用于 PythonAnywhere，您需要提供--user选项）。如果要在虚拟环境之外为不同版本的 Python 安装包，请使用pipX.X install --user ...（其中X.X应替换为所需的 Python 版本）。此外，请记住每次更改设置时重新加载 Web 应用程序。如果你真的被卡住了，也许可以尝试联系 PythonAnywhere 支持 (support@pythonanywhere.com) 或使用他们的论坛？
