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。该应用程序在我使用 Anaconda 和 Python 3.5 的本地计算机上成功运行。我无法将其推送到 Heroku。根据命令

>git push heroku master

我不确定为什么我无法在 Heroku 中将 requests 模块安装为 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

Answer 1

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

您需要在使用 pip（使用 requirements.txt）或 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，忽略您的 requirements.txt 文件。

要么

• 将您的需求移至您的 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、提交并推送（以使用 Pipenv），或者
• 删除Pipfile 和Pipfile.lock，在本地使用pip（或pip-tools 或类似名称），提交并推送（以使用pip）。
