Heroku: ModuleNotFoundError :没有名为“请求”的模块

Question

我正在尝试将Django程序部署到Heroku。应用程序在我的本地机器上成功运行，它使用了Anaconda和Python3.5。我不能把它推到Heroku。听从命令

>git push heroku master

我不知道为什么我不能让requests模块安装在Heroku中的pip。它在我的requirements.txt文件中：

Django==2.1.7
dj-database-url==0.5.0
dj-static==0.0.6
gunicorn==19.9.0
Unipath==1.1
python-decouple==3.1
Pillow==3.3.0
Markdown==3.0.1
bleach==3.1.0
psycopg2==2.7.7
whitenoise==4.1.2
requests==2.21.0
requests-oauthlib==1.0.0

Heroku构建的输出显示，除了Pipfile和Pipfile.lock之外，还有一个requirements.txt。

您需要在使用pip (使用requirements.txt)还是Pipenv (使用Pipfile和Pipfile.lock)之间进行选择。如果所有三个文件都存在，Heroku将使用Pipenv安装，而忽略您的requirements.txt文件。

任一

• 将您的需求移动到您的Pipfile并在本地运行Pipenv以安装它们并更新您的Pipfile.lock、删除您的requirements.txt、提交和推送(使用Pipenv)，或
• 删除Pipfile和Pipfile.lock，在本地使用pip (或pip-tools或类似的)，提交和推送(使用pip)。
