I have written a script called coinview.py and it can run on linux. When I trying to run it as systemd, it raises error

我已经编写了一个名为coinview.py的脚本，它可以在Linux上运行。当我尝试以SYSTEM D身份运行它时，出现错误

error:ImportError: No module named 'schedule'.

错误：ImportError：没有名为‘Schedule’的模块。

I use pip3 show schedule, it already exist. So i have no idea what's wrong with my script.

我用的是PIP3节目时间表，它已经存在了。所以我不知道我的剧本出了什么问题。

I print sys.executable and sys.path in systemd.

我在system d中打印sys.executable和sys.path。

According to these logs, i found that the PYTHONPATH is different in manual shell and systemd.And i try to add "/home/ubuntu/.local/lib/python3.5/site-packages" into /etc/profile but systemd logs show that it still can't found the path.

根据这些日志，我发现PYTHONPATH在手动外壳和系统中是不同的，我尝试在/“/home/ubuntu/.local/lib/python3.5/site-packages”/Profile中添加配置文件，但系统日志显示仍然找不到路径。

So i do a stuip thing, add

所以我做了一件很有趣的事，加

sys.path.append("/home/ubuntu/.local/lib/python3.5/site-packages") 

in my code, and it works...

在我的代码中，它起作用了..。

Install the package for root with

使用以下命令安装根目录的程序包

sudo pip install schedule

Or instead of running it as root, try running it as another specific user.
Modify your .service to something like:

或者，尝试以另一个特定用户的身份运行它，而不是以超级用户身份运行。将您的.service修改为类似以下内容：

[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]

Hope that helps!

希望这能有所帮助！
