Fatal error in launcher: Unable to create process using 错误解决以及python3安装scrapy

因为要学scrapy

特意在电脑安装了python2和python3

在python3下安装scrapy时报错

D:\python3\Scripts>pip3.6.exe install scrapy
Fatal error in launcher: Unable to create process using

想了想突生妙计

解决办法：

D:\python3\Scripts>python3 pip3.6.exe install scrapy

成功下载

此时后面会报错

D:\python3\Scripts>python3 pip3.6.exe install scrapy
