编译python失败(权限被拒绝！)同时在heroku中部署一些更改

Question

我在heroku部署了一个github项目。然后，我用heroku slugs:download -a newocas成功地用我的个人电脑克隆了这个项目。

现在，在进行了一些更改并在将项目部署回heroku时执行提交后，会一次又一次地产生相同的错误。

我使用git bash进行提交和部署。下面是我的错误消息：

​

这是我的requirement.txt文件

Flask==0.10.1 future==0.16.0

我试过这个- Pip not found when deploying Django app to Heroku，this- Push rejected, failed to compile Python app，this- Heroku push rejected, failed to compile Python/django app (Python 2.7)和this - Heroku/python failed to detect set buildpack

但是错误还是会发生的！

有人能帮我一下吗？

Answer 1

我已经解决了这个问题。我分享下面的程序：

首先，在这种情况下，使用heroku slugs:download -a newocas是行不通的。当该应用程序已经下载使用鼻涕虫，那么它就不能链接到heroku之后。

因此，解决方案是使用git在pc中克隆应用程序，然后在任何更改之后提交，然后将更改推送到heroku app.。
