win10 安装pymilvus_orm 编译mmh3报错

一、需要安装C++编译工具，按照提示网站下载C++编译工具 并安装https://visualstudio.microsoft.com/downloads/

Installing collected packages: mmh3

Running setup.py install for mmh3 ... errorERROR: Command errored out with exit status 1:command: 'd:\envs\article_spider\scripts\python.exe' -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\\Users\\HP\\AppData\\Local\\Temp\\pip-install-hjy8hpiw\\mmh3\\setup.py'"'"'; __file__='"'"'C:\\Users\\HP\\AppData\\Local\\Temp\\pip-install-hjy8hpiw\\mmh3\\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record 'C:\Users\HP\AppData\Local\Temp\pip-record-qn4etedo\install-record.txt' --single-version-externally-managed --compile --install-headers 'd:\envs\article_spider\include\site\python3.8\mmh3'cwd: C:\Users\HP\AppData\Local\Temp\pip-install-hjy8hpiw\mmh3\Complete output (5 lines):running installrunning buildrunning build_extbuilding 'mmh3' extensionerror: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

二、安装完后，还是报错，关键错误如下：

elease\mmh3module.obj
mmh3module.cpp

请找到编译工具目录C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\MSVC\14.36.32532\include，（每个机器不同，可以在C盘搜索stdint.h），并找到stdint.h文件，用文本打开修改

修改后如下，保存再次安装编译成功
