The script scrapy is installed in ‘/home/xxx/.local/bin’ which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

解決方法：

export PATH=/home/zzq/.local/bin/:$PATH

當然這只是暫時解決問題，下次還是不行。要想一直可以的話，就要把這句話，寫到~/.zshrc或者~/.bashrc中
寫到那一個都沒問題啦。
bash的用：~/.bashrc
zsh的用：～/.zshrc

sudo vim ~/.zshrc 
#把export PATH=/home/zzq/.local/bin/:$PATH  放到最后
source ~/.zshrc  
#就好了
