【问题讨论】：

Pip 找不到virtualenv==1.8.4.post1 的要求。您要么需要将其更改为1.8.4（当前版本）。但是，通常情况下，virtualenv 根本不会放在要求中 - 除非您的应用程序的功能依赖它。

我把它从需求中去掉了，得到了同样的错误。

请发布您的项目的文件结构，包括您的根文件夹以及您的.git repo 文件夹所在的位置。

不确定我是否做得对，但它就是这样。根目录：.git、hellodjango、venv、.gitignore、manage.py、Procfile.txt、requirements.txt。

编辑原始线程，以便您可以显示文件和文件夹结构。与这篇文章类似（只是一个文件结构的随机帖子供参考）：***.com/questions/12398460/django-app-file-structure

【参考方案1】：

我能够通过以下方式运行它：

克隆你的 git 仓库 从您的requirements.txt 中删除virtualenv==1.8.4 git add . git commit -m "removing virtualenv requirement" git push heroku master

我假设您在从您的要求中删除 virtualenv 后没有 git add . 和 git commit。你对git repo 所做的任何更改都不会生效，对于github 和heroku，直到你add 然后commit 本地更改，最后push 他们到远程存储库即Github 或 Heroku。

【讨论】：

非常感谢您花时间帮助我！就我而言，这是一个粗心的错误。

【参考方案2】：

对于 heroku 部署，您不需要在 requirements.txt 文件中的 virtualenv==1.8.4.post1，请将其删除并将 procfile 和需求放在 git 的根目录中。

【参考方案3】：

错误消息表明它找不到virtualenv==1.8.4.post1，当我在本地尝试该命令时，我得到了同样的错误。 pypi 中似乎不存在该版本。尝试将您的 requirements.txt 更改为 virtualenv==1.8.4？
