我正在尝试关注Heroku的python快速入门指南，但我遇到了一些问题。目前，“git push heroku master”失败了，因为它无法安装Bonjour。有谁知道这是否是一个真正必要的要求，我是否可以更改所需的版本，或以其他方式修复此问题？推文全文如下。

答案 0 :(得分：10)
也许你正在使用虚拟环境而你忘了激活它
在这种情况下，根据您在项目中存储虚拟环境的方式，您可能首先需要
source venv/bin/activate
之后冻结你的要求
pip freeze > requirements.txt
最后
git push heroku master
答案 1 :(得分：7)
您是否尝试从快速入门推送示例应用？您根本不需要安装许多要求。
我怀疑您在推荐的virtualenv之外创建了您的需求文件，并且在您的系统python安装中安装了twisted和bonjour-py包。
答案 2 :(得分：3)
为什么{！1}}位于您的requirements.txt文件中？删除它应该可以解决您的问题。
此外，我似乎无法安装它，所以难怪Heroku在那里失败。
bonjour-py答案 3 :(得分：0)
我在bonjour-py中引用requirements.txt的某个项目通常遇到同样的问题，目前还不知道该跟踪哪个项目或如何跟踪该项目。
有人告诉我 pip-tool 。它实际上是识别您拥有的，以及是否要更新它们的绝佳选择。作为奖励，它忽略了bonjour-py错误。
