如何解决使用 2captcha 库推送到 Heroku 时出错 - ModuleNotFoundError：没有名为“请求”的模块
我收到此错误 - ModuleNotFoundError：当我运行 git push heroku master 时，没有名为“请求”的模块。它是说我的 requirements.txt 中没有请求，但它显然在那里。我相信由于 2captcha-python 正在发生一些奇怪的事情。关于如何解决此错误的任何想法？包括我的 requirements.txt 文件和下面的错误日志。

解决方法
pip 首先下载所有模块，然后安装它们。因此，当 pip 下载 2captcha 时，requests 已下载但尚未安装。这会产生问题。
您必须先安装除 2captcha 之外的所有模块，然后再安装 2captcha。或者先只安装 requests，然后再安装其他模块。
编辑：
我无法对其进行测试，但在文档中您可以看到它也可以使用 setup.py 来安装模块。但我不知道它是否会同时运行 setup.py 和 requirements 或仅运行其中之一。
在 venv 的本地计算机上，我使用 setup.py
from setuptools import setup
setup(
install_requires=['requests','wheel'],)
import subprocess
subprocess.run('python -m pip install 2captcha-python',shell=True)
并运行 python setup.py install（但 Heroku 应自动运行）
稍后我将在 Heroku 刷新帐户时对其进行测试。
