1、conda安装
conda install Scrapy或者conda install -c conda-forge scrapy安装的版本可能不是最新的：
C:\Users\m>conda search scrapy
Loading channels: done

scrapy 1.6.0 py38_0 pkgs/main
而且总是报错：
Preparing transaction: done
Verifying transaction: done
Executing transaction: failed
ERROR conda.core.link:_execute(502): An error occurred while installing package 'defaults::automat-0.8.0-py_0'.
CondaError: Cannot link a source that does not exist. D:\Anaconda3\Scripts\conda.exe
Running `conda clean --packages` may resolve your problem.
Attempting to roll back.
2、pip安装
C:\Users\m>pip install scrapy
报了一个错：
automat 20.2.0 has requirement attrs>=19.2.0, but you'll have attrs 18.1.0 which is incompatible.
命令行安装最新版本，或者指定一个版本：
C:\Users\m>pip install attrs==19.3
安装成功后再次运行pip install scrapy。
