Mac电脑，OSX10.15.3，
之前已经在电脑上彻底删除python2，只装了python3，在安装scrapy，能安装成功，但是终端使用scrapy命令要吗说command not found: scrapy要吗说permission denied: scrapy，网上各种百度，各种方法都是无效的，别人说pip3 uninstall scrapy后重装可以，但是我无效。最后采用命令
python3 -m pip install scrapy
安装成功，
在环境变量中增加
export PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin"
有了这个才是安装成功！
