Question

我是其中一个有幸拥有破解SSL的公司代理的人！ / s的

我的环境已正确配置http_proxy，https_proxy，HTTP_PROXY和HTTPS_PROXY。我通过/etc/profile.d中的shell脚本进行配置，为我设置所有4个环境变量。

我试图使用Ansible从pip安装软件包。这是我的问题。

我可以登录系统并输入以下命令：

pip install --trusted-host pypi.python.org robotframework

......它会起作用。我尝试使用command和pip模块从Ansible内部做同样的事情。没有快乐。

使用pip模块：

- name: install robotframework
  pip: name=robotframework extra_args='--trusted-host pypi.python.org'
  become: true

结果如下：

fatal: [localhost]: FAILED! => {"changed": false, "cmd": "/bin/pip install --trusted-host pypi.python.org robotframework", "failed": true, "

使用command模块：

- name: install robotframework
  command: "pip install --trusted-host pypi.python.org robotframework"
  become: true

结果如下：

我完全不知所措。我认为对root用户来说可能是有趣的，直到我以root用户身份登录并成功在shell上运行pip命令。我知道我的旧版本的pip（感谢EPEL），但这不应该导致command调用失败。即使我尝试像警告状态一样升级pip，我也会得到相同的结果。

唯一有效的方法是在任务中冗余地指定代理URL：

- name: install robot framework
  pip: name=robotframework extra_args='--trusted-host pypi.python.org'
  environment:
    http_proxy: http://proxy1.example.com:8080
    https_proxy: http://proxy1.example.com:8080
    HTTP_PROXY: http://proxy1.example.com:8080
    HTTPS_PROXY: http://proxy1.example.com:8080
  become: true
  become_user: root

为什么我需要这样做？如果我以root身份登录，我可以看到设置了环境变量。我也不需要在Ansible中设置它们。

如果我以root身份登录，我可以看到设置了环境变量。我也不需要在Ansible中设置它们。

不正确！ :)您可能会在~/.bashrc这样的文件中设置这些变量，该文件仅在交互式 shell上运行。

有a section of the documentation致力于处理环境变量，特别强调代理使用。

为什么不能遵守我的系统代理设置？
