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"并等待。

它总是在以下 ansible 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

那么为什么失败并且其他 pip 安装工作正常，我可以使用任务修改来获得相同的目标吗？

这是显示的错误：

这里的问题是镜子的价值，它找不到它：

{{ 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'

我会尝试将其更改为专门的其他镜像并最初使用http（因为日志中可能存在问题https）：

http://b.pypi.python.org/simple or
http://c.pypi.python.org/simple or
http://d.pypi.python.org/simple

您也可以尝试在剧本中省略该选项：

-i {{ COMMON_PYPI_MIRROR_URL }}

根据他们提到外壳上的or 设置应该足够的文档。--use-mirrorsexport PIP_USE_MIRRORS=true
