I want to download python-docx and i am not so familiar with python libraries, pip and installing this way.我想下载 python-docx，但我不太熟悉 python 库、pip 和这种安装方式。 If I try this I get some errors.如果我尝试这样做，我会得到一些错误。

First it said that it couldn't build a wheel for lxml and that I needed microsoft visual C++ 2014 so I downloaded microsoft visual studio and installed the C++ build tools.首先它说它不能为 lxml 构建轮子并且我需要 microsoft visual C++ 2014 所以我下载了 microsoft visual studio 并安装了 C++ 构建工具。 Than that error dissapeared but now it sais it can't build the wheel and "Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?"比那个错误消失了但现在它说它无法构建轮子并且“无法在库 libxml2 中找到 function xmlCheckVersion。是否安装了 libxml2？” I tried downloading the zip file libxml2 and putting it where python is stored butnothing works.我尝试下载 zip 文件 libxml2 并将其放在存储 python 的位置，但没有任何效果。

Okay after an hour of searching:) I found something that works.好的，经过一个小时的搜索:) 我找到了一些有用的东西。 So for the beginners like me I'll explain it very simple.所以对于像我这样的初学者，我会解释得很简单。

  1. First download the right lxml file here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml首先在这里下载正确的lxml文件： http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
  2. Then type this in cmd: pip install C:\path\to\downloaded\file\lxml‑4.5.2‑cp39‑cp39‑win32.whl but ofc change the path to where you stored the file you just downloaded.然后在 cmd 中键入： pip install C:\path\to\downloaded\file\lxml‑4.5.2‑cp39‑cp39‑win32.whl 但 ofc 将路径更改为存储刚刚下载的文件的位置。 Now you have lxml installed and the error should be gone.现在你已经安装了 lxml，错误应该消失了。
