我对 python 和 scrapy 完全陌生。我已经使用python ok 几天了，想添加scrapy。我尝试通过命令提示符安装scrapy，输入“pip install scrapy”。它下载了一些东西，开始安装，但很快就失败了。以下是大量错误日志的最后几行；

错误：命令出错，退出状态为 1：'c:\users\thega\appdata\local\programs\python\python38-32\python.exe' -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\Users\thega\AppData\Local\Temp\pip-install-o99u8knn\Twisted\setup.py'"'"'; 文件='"'"'C:\Users\thega\AppData\Local\Temp\pip-install-o99u8knn\Twisted\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(file);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, file, '"'"'exec'"'"'))' 安装--record 'C:\Users\thega\AppData\Local\Temp\pip-record-b2nn016h\install-record.txt' --single-version-externally-managed --compile 检查日志以获取完整的命令输出。

您是否安装了 Microsoft Visual C++ 14.0？

错误日志的最后一行写着：

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/"

该链接对我来说很好。
