Pip 为什么不是'；是否负责我的系统代理设置？

我是那些幸运的人之一，有一个破坏SSL的公司代理/

我的环境已正确配置了http\U代理、https\U代理、http\U代理和https\U代理。我通过/etc/profile.d中的shell脚本进行配置，该脚本为我设置了所有4个环境变量

我正在尝试使用Ansible从pip安装软件包。这是我的问题

我可以登录到系统并键入以下命令：

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

。。。它会起作用的。我试着在Ansible内部使用

command

和

pip

模块做同样的事情。没有快乐

使用

pip

模块：

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

- 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root用户可能很有趣，直到我以root用户身份登录并在shell中成功运行pip命令。我知道我使用的是旧版本的pip（感谢EPEL），但这不应该导致

命令调用失败。即使我尝试像警告状态那样升级pip，我也会得到同样的结果

唯一有效的方法是在任务中冗余指定代理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

我为什么要这样做？如果我以root用户身份登录，我可以看到环境变量已设置。我也不需要把它们放在Ansible里

如果我以root用户身份登录，我可以看到环境变量已设置。
我也不需要把它们放在Ansible里

不正确！：）您可能正在像
~/.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

这里专门介绍了如何处理环境变量，特别强调了代理的使用
