在这个例子中，Django-cities 失败了。

- hosts: localhost
  tasks:
   - name: Install Django
     pip: name=Django
   - name: Install Userena
     pip: name=django-userena
   - name: Install Django Messages
     pip: name=https://github.com/arneb/django-messages/archive/master.zip
   - name: Install Django Cities
     pip: name=git+https://github.com/coderholic/django-cities.git@d0163f393e7557914b3f2c6882e740537ca63fd6

错误：

Ansible 中不允许通过 pip 安装 git 提交吗？

【解决方案1】：

如果你在命令行上运行，你会得到同样的错误：

$ pip install -e git+https://github.com/coderholic/django-cities.git@d0163f393e7557914b3f2c6882e740537ca63fd6
--editable=git+https://github.com/coderholic/django-cities.git@d0163f393e7557914b3f2c6882e740537ca63fd6 is not the right format; it must have #egg=Package

您可以在其中添加#egg=packagename，它会起作用：

$ pip install -e git+https://github.com/coderholic/django-cities.git@d0163f393e7557914b3f2c6882e740537ca63fd6#egg=django-cities
Obtaining django-cities from git+https://github.com/coderholic/django-cities.git@d0163f393e7557914b3f2c6882e740537ca63fd6#egg=django-cities
  Cloning https://github.com/coderholic/django-cities.git (to d0163f393e7557914b3f2c6882e740537ca63fd6) to src/django-cities

所以只需将#egg=django-cities 添加到 Ansible 中的 URL 即可。

请注意，我建议您引用您的 git+https://....#egg=xyz yaml。里面有很多魔法人物。
