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

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。
