Flask 不会在 PythonAnywhere 中使用我安装的模块
Flask Wont use my Installed Modules in PythonAnywhere
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

我已经浏览了所有我能找到的关于如何解决这个问题的网站，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，在转移到 PythonAnywhere 之前它运行良好。我一直在努力解决这个问题大约两周 ^~^ 但仍然没有运气。我用了很多 this guide 来帮助我，因为我也在练习我的网络部署技能。 （不需要判断我正在使用烧瓶 -3- 的事实）但是有人可以花时间帮助我吗？可以的话，万分感谢
检查您在 PythonAnywhere 上的网络应用程序是否被 Python 设置为 运行 2.7 -- 我看到您在 pip install 之外使用虚拟环境，默认情况下将为 Python 2.7 使用 pip，如您在输出中所见（顺便说一句，它不适用于 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 安装软件包，请使用 pipX.X install --user ...（其中 X.X 应替换为所需的 Python 版本）。另外，请记住每次更改设置时都要重新加载网络应用程序。如果您真的遇到困难，也许可以尝试联系 PythonAnywhere 支持 (support@pythonanywhere.com) 或使用他们的论坛？
你好@TutorialWarrior9776 我的建议是：
步骤 1：
安装虚拟环境，
pip install virtualenv
第 2 步：
创建环境
virtualenv -p python3.8 NAME_ENV
步骤 3：
激活 env 并安装 requirements.txt（本地机器生成的文件包含模块 flask_migrate）
source NAME_ENV/bin/active
pip install -r requirements.txt
步骤 4：
在 pythonanywhere 的 (web) 部分设置你的 env 路径，仅此而已；

（部分：第 3 步：配置您的应用程序以使用此 virtualenv）
希望对您有所帮助 ;)
