我在运行 Amazon Linux 2 的 AWS EC2 实例上克隆了一个 Node.js 应用程序。
server.js我可以很好地执行项目的文件：
[ec2-user@ip-*********** portfolio_v3]$ nvm use 16
Now using node v16.19.1
[ec2-user@ip-*********** portfolio_v3]$ MAIL_JET_API_KEY_PRIVATE="..." NYT_API_KEY="..." node server.js
...
我正在尝试创建一个 systemd 服务，以便该应用程序始终运行，并且正在跟随本演练
我有以下内容/etc/systemd/system/portfolio-v3.service
[Unit]
Description=portfolio-v3
After=multi-user.target
[Service]
Environment=MJ_API_KEY_PRIVATE=1234567890
Environment=NYT_API_KEY=1234567890
ExecStart=/home/.nvm/versions/node/v16.19.1/bin/node /home/ec2-user/portfolio-v3/server.js
Restart=always
RestartSec=10
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=portfolio-v3
User=ec2-user
[Install]
WantedBy=multi-user.target
我已经以不同的顺序运行了以下所有命令：
sudo chmod 644 /etc/systemd/system/portfolio-v3.service
sudo systemctl daemon-reload
sudo systemctl enable portfolio-v3.service
sudo systemctl start portfolio-v3.service
但我不断看到以下内容：
$ sudo systemctl status portfolio-v3.service
● portfolio-v3.service - portfolio-v3
Loaded: loaded (/etc/systemd/system/portfolio-v3.service; enabled; vendor preset: disabled)

谢谢 ：）

尝试server.js直接使用我想要的节点版本的绝对路径运行也失败：
