If somebody could help me I would really appreciate it! I have a suspicion that the issue has to do with multiple versions of python but I'm not sure how to check or fix that.
如果有人能帮助我,我将不胜感激!我怀疑这个问题与 python 的多个版本有关,但我不确定如何检查或修复它。

It looks like you're having a permissions error, based on this message in your output: error: could not create '/lib/python2.7/site-packages/lxml': Permission denied. 
根据输出中的以下消息,您似乎遇到了权限错误:error: could not create '/lib/python2.7/site-packages/lxml': Permission denied。
One thing you can try is doing a user installof the package with pip install lxml --user. For more information on how that works, check out this StackOverflow answer. (Thanks to Ishaan Taylor for the suggestion)
有一两件事你可以尝试做一个用户安装包带的pip install lxml --user。有关其工作原理的更多信息,请查看此 StackOverflow 答案。(感谢 Ishaan Taylor 的建议)
You can also run pip installas a superuser with sudo pip install lxmlbut it is not generally a good idea because it can cause issues with your system-level packages.
您也可以pip install以超级用户身份运行,sudo pip install lxml但这通常不是一个好主意,因为它可能会导致您的系统级软件包出现问题。

On a Mac, you need to use this command:
在 Mac 上,您需要使用以下命令:

Set up a virtualenv:
设置一个virtualenv:
% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py 
% sudo python /tmp/get-pip.py
These commands install pip into the global site-packages directory.
这些命令将 pip 安装到全局站点包目录中。
% sudo pip install virtualenv
and ditto for virtualenv:
和 virtualenv 同上:
% mkdir -p ~/.virtualenvs
I like my virtualenvs under one tree in my home directory called .virtualenvs
我喜欢我的主目录中的一棵树下的 virtualenvs .virtualenvs
% virtualenv ~/.virtualenvs/lxmltest
Creates a virtualenv.
创建一个 virtualenv。
% . ~/.virtualenvs/lxmltest/bin/activate
Removes the need to specify the full path to pip/python in this virtualenv.
无需在此 virtualenv 中指定 pip/python 的完整路径。
% pip install lxml
Alternatively execute ~/.virtualenvs/lxmltest/bin/pip install lxmlif you chose not to follow the previous step. Note, I'm not sure how far along you are, so some of these steps can be safely skipped. Of course, if you mess something up, you can always rm -Rf ~/.virtualenvs/lxmltestand start again from a new virtualenv.
或者,~/.virtualenvs/lxmltest/bin/pip install lxml如果您选择不执行上一步,则执行。请注意,我不确定您已经走了多远,因此可以安全地跳过其中一些步骤。当然,如果你搞砸了,你总是可以rm -Rf ~/.virtualenvs/lxmltest从一个新的 virtualenv 重新开始。
