无法找到 vcvarsall.bat 错误

Question

我正在使用 Python 版本 3.5.2。

我正在尝试编辑 MSWord 文档中的单词和段落。

在此之前，我需要安装 docx 模块。

在命令行中，我将其指向路径：

C:\Users\d\AppData\Local\Programs\Python\Python35-32\Scripts

并输入：

pip install python-docx.

点击 return 后，我收到此错误消息（完整输出如下）：

"unable to find vcvarsall.bat".

我该如何解决这个错误？

Answer 1

这是在 Windows 上安装 lxml Python 库的一个众所周知的问题。

此处的 TL;DR 版本是您从预编译的 "binary installation package" 安装 lxml，并为您处理所有细节。

您可以在这里找到其中之一： http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml

'cp' 段代表 'C Python'（例如常规 Python，与 PyPy 相对）和版本，因此如果您使用的是 Python 2.7您想要名称中带有 -cp27- 的软件包之一。其中有两种，一种用于 32 位，一种用于 64 位。您可能需要 32 位，因为 .

下载二进制安装包（"wheel"）后，使用pip进行安装，例如：

pip install lxml‑3.6.4‑cp27‑cp27m‑win32.whl
