我正在尝试按照https://github.com/edx/configuration/wiki/edX-Ubuntu-12.04-64-bit-Installation安装EdX 。
甚至我只需要运行sudo ansible-playbook -c local ./edx_sandbox.yml -i“ localhost”，然后等待。
它总是在以下可完成的任务上失败：
# Install the python modules into {{ edxapp_venv_dir }}
- name : install python base-requirements
# Need to use shell rather than pip so that we can maintain the context of our current working directory; some
# requirements are pathed relative to the edx-platform repo. Using the pip from inside the virtual environment implicitly
# installs everything into that virtual environment.
shell: >
{{ edxapp_venv_dir }}/bin/pip install -i {{ COMMON_PYPI_MIRROR_URL }} --exists-action w --use-mirrors -r {{ base_requirements_file }}
chdir={{ edxapp_code_dir }}
environment: "{{ edxapp_environment }}"
sudo_user: "{{ edxapp_user }}"
notify:
- "restart edxapp"
- "restart edxapp_workers"
when: not inst.stat.exists or new.stat.md5 != inst.stat.md5
那么，为什么失败了，而其他pip安装仍能正常工作，我可以通过任务修改来达到相同的目标吗？
这是显示的错误：

这里的问题是镜像的值，并且找不到它：
{{ COMMON_PYPI_MIRROR_URL }}
该值在edx-west/roles/common/defaults/main.yml文件中设置：
COMMON_PYPI_MIRROR_URL: 'https://pypi.python.org/simple'
我会尝试将其专门更改为其他镜像，并在最初使用http（因为https日志中可能存在问题）：
http://b.pypi.python.org/simple or
http://c.pypi.python.org/simple or
http://d.pypi.python.org/simple
您也可以尝试省略剧本中的选项：
-i {{ COMMON_PYPI_MIRROR_URL }}
根据他们提到外壳上的或设置应该足够的文档。--use-mirrorsexport PIP_USE_MIRRORS=true
