通过Ansible Playbook对特定git提交的Pip安装失败

Question

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：

fatal: [localhost]: FAILED! => {"changed": false, "cmd": "/usr/bin/pip2 install -e git+https://github.com/coderholic/django-cities.git@d0163f393e7557914b3f2c6882e740537ca63fd6",

在Ansible中是否不允许通过pip安装git commit？

Answer 1

如果在命令行上运行以下命令，您将得到相同的错误：

$ 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

你可以添加一个#egg=packagename到它上面，它将会工作：

$ 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

因此，只需在Ansible中将#egg=django-cities添加到URL中，就可以了。

注意:我建议您引用您的git+https://....#egg=xyz yaml。里面有很多神奇的角色。
