系统尚未使用 systemd 作为 init system (PID 1) 引导。不能操作。无法连接到总线：主机已关闭

Question

我正在尝试在谷歌云终端中使用以下命令创建 systemd 服务后激活服务：

vim /etc/systemd/system/app.service

将以下内容粘贴到此文件中：

#vim /etc/systemd/system/app.service
[Unit]
#  specifies metadata and dependencies
Description=Gunicorn instance to serve myproject
After=network.target
# tells the init system to only start this after the networking target has been reached
# We will give our regular user account ownership of the process since it owns all of the relevant files
[Service]
# Service specify the user and group under which our process will run.
User=clashgamers2021
# give group ownership to the www-data group so that Nginx can communicate easily with the Gunicorn processes.
Group=www-data
# We'll then map out the working directory and set the PATH environmental variable so that the init system knows where our the executables for the process are located (wi$
WorkingDirectory=/home/clashgamers2021/clashgamers/
Environment="PATH=/home/clashgamers2021/clashgamers/env/bin"
# We'll then specify the commanded to start the service
ExecStart=/home/clashgamers2021/clashgamers/env/bin/gunicorn --workers 3 --bind unix:app.sock -m 007 wsgi:app
# This will tell systemd what to link this service to if we enable it to start at boot. We want this service to start when the regular multi-user system is up and running:
[Install]
WantedBy=multi-user.target

为了激活这项服务，我输入了：

sudo systemctl start app
sudo systemctl enable app

但是我得到了这个错误：

clashgamers2021@cloudshell:~/clashgamers (clash-gamers-318206)$ sudo systemctl start app
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

您正在尝试运行Cloud Shell 中的命令：

Cloud Shell 是 Google Cloud 的交互式 shell 环境，可让您轻松学习和试验 Google Cloud，并通过网络浏览器管理您的项目和资源。

Create a new VM（指定硬件和操作系统）并在 Cloud Console 中使用 SSH button 或使用文档中描述的其他方法连接到它。

然后运行您的命令，如果它们不起作用，请使用更多详细信息更新您的问题。
