我正在尝试在Ubuntu 18.04上安装scrapyd。因此我做了一个
pip3 install scrapyd
现在以某种方式将其安装在我的本地目录下：
merlin@spider1:~$ scrapyd
2020-05-03T15:16:17+0200 [-] Loading /home/merlin/.local/lib/python3.8/site-packages/scrapyd/txapp.py...
2020-05-03T15:16:17+0200 [-] Scrapyd web console available at http://127.0.0.1:6800/
2020-05-03T15:16:17+0200 [-] Loaded.
寻找conf文件：
merlin@spider1:~$ locate scrapyd.conf
/home/merlin/.local/lib/python3.8/site-packages/scrapyd/default_scrapyd.conf
我第二次尝试：
merlin@spider1:~$ sudo pip3 install scrapyd

Successfully installed scrapyd-1.2.1
以某种方式不起作用：
$ scrapyd
-bash: /home/merlin/.local/bin/scrapyd: No such file or directory
如何在/ etc / scrapyd下安装scraypd？
sudo -H pip3 install scrapyd
