将Django项目推送到Heroku时出错

Question

我已经尝试了一个小时来解决这个错误，但我已经没有办法了，所以请帮帮我。

heroku create

这个命令运行得很好，没有问题。

git push heroku master

Answer 1

在Heroku部署的时候，你不需要在requirements.txt文件里写virtualenv==1.8.4.post1，请把它删掉，并把procfile和requirements文件放在git的根目录下。

Answer 2

这个错误信息说明找不到 virtualenv==1.8.4.post1 这个版本。当我在本地尝试这个命令时，也出现了同样的错误。看起来在 pypi 上没有这个版本。你可以试着把你的 requirements.txt 文件里的内容改成 virtualenv==1.8.4 吗？

Answer 3

我通过以下步骤成功运行了这个：

1. 克隆你的git仓库
2. 从你的requirements.txt文件中删除virtualenv==1.8.4
3. 执行git add .
4. 执行git commit -m "移除virtualenv依赖"
5. 执行git push heroku master

我猜想你在从依赖中移除virtualenv后，没有执行git add .和git commit。在你本地做的任何更改，只有在你执行add和commit之后，才会对github和heroku生效，最后还需要将这些更改push到远程仓库，也就是Github或Heroku。
