参考前面写的一篇博客：https://blog.****.net/zimojiang/article/details/103869843

安装Scrapy框架

conda install scrapy

错误重现

输入scrapy之后出现如下错误：

Fatal error in launcher: Unable to create process using
'“d:\bld\scrapy_1572360388337_h_env\python.exe”
“D:\Anaconda3\envs\learn2\Scripts\scrapy.exe”

解决办法

前面加上python -m 表示将scrapy 作为包引用

(base) C:\Users\HP>activate learn2

(learn2) C:\Users\HP>scrapy
