1.遇到问题啦

我在兴致勃勃的安装包，什么？你居然安装不下来？

pip install paddleocr paddlenlp paddlespeech moviepy

夸嚓，一下子，红颜色字就出来了，这怎么整？

2.网上的解决办法

查看错误信息，给出的是 error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": visualstudio.microsoft.com/visual-cpp-…

看出来是需要新版本的 Microsoft C++ Build Tools，并给出了地址，这个要记下来，接下来要考。打开网址：visualstudio.microsoft.com/zh-hans/vis… ，Microsoft C++ 生成工具，独立 MSVC 编译器、库和脚本。直接下载就是。

3.安装Microsoft C++ 生成工具

点击单个组件，电机安装MSVC v143-VS 2022 C++ x64/86生成工具（最新），安装即可，接下来再试试。

4.原因剖析

4.1原版解释

Even though Python is an interpreted language, you may need to install Windows C++ compilers in some cases. Unlike Linux, compilers for Windows are not included by default in the OS.

For example, you will need to use them if you wish to:

Install a non-pure Python package from sources with Pip (if there is no Wheel package provided).
Compile a Cython or Pyrex file.

4.2中文意思

尽管Python是一种解释型语言，但在某些情况下可能需要安装Windows c++编译器。与Linux不同，Windows的编译器在默认情况下不包括在操作系统中。因此，你需要安装编译器

用源码安装一个非纯python的包
编译cython 或 Pyrex 文件

具体可以看python文档，说的比较细致： wiki.python.org/moin/Window… ，并给出了版本搭配。

Visual C++	CPython
14.x	3.5 - 3.10
10.0	3.3 - 3.4
9.0	2.6 - 2.7, 3.0 - 3.2

当你安装包遇到【 error: Microsoft Visual C++ 14.0 or greater is required】怎么办？
