我最近发现,scrapy是一个很好的抓库工具,因此我尝试在我的机器上安装scrapy,但是当我尝试进行pip install scrapy安装时,它安装了一段时间并抛出了此错误.
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

Command "d:\pycharmprojects\environments\scrapyenv\scripts\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\User\\AppData\\Local\\Temp\\pip-build-arbeqlly\\Twisted\\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\User\AppData\Local\Temp\pip-jdj93131-record\install-record.txt --single-version-externally-managed --compile --install-headers d:\pycharmprojects\environments\scrapyenv\include\site\python3.5\Twisted" failed with error code 1 in C:\Users\User\AppData\Local\Temp\pip-build-arbeqlly\Twisted所以之后我去了this网站并安装了python工具.
但是在安装结束时获得此信息：
