[英]ImportError: No module named 'schedule' when i using system to run a service
我編寫了一個名為coinview.py
的腳本,它可以在linux上運行。 當我嘗試將其作為systemd
運行時,會引發錯誤
error:ImportError: No module named 'schedule'.
我使用pip3
show schedule,它已經存在。 所以我不知道我的腳本有什么問題。
我在systemd中打印sys.executable和sys.path。

安裝root用程序包
sudo pip install schedule
或者不是以root身份運行它,而是嘗試將其作為另一個特定用戶運行。 將您的.service修改為:
[Unit]
Description=coinview deamon
After=rc-local.service
[Service]
Type=simple
User=user
WorkingDirectory=/home/ubuntu/source/quotation_api
ExecStart=/usr/bin/python3 coinview.py
Restart=always
[Install]

希望有所幫助!
根據這些日志,我發現PYTHONPATH在手動shell和systemd中是不同的。我嘗試將“/home/ubuntu/.local/lib/python3.5/site-packages”添加到/ etc / profile但systemd日志中表明它仍然找不到路徑。
所以我做一個stuip的事情,補充一下
sys.path.append("/home/ubuntu/.local/lib/python3.5/site-packages")
在我的代碼中,它的工作原理......
