    通过命令行可以启动:

    所以, 这个 service 到底该怎么写呢?

    你的 service 应该是放到 system 里的,然而你系统里默认 node 版本比较低,而你通过 nvm 安装的最新版本的 node 无法直接在 systemctl 里被用到,所有出现报错了。
    解决方式,要么把最新版的 node 安装在全局里,要么把这个 service 放到 systemctl user 里,然后在设置正确的环境变量。

    BTW: 你最好把项目里 package.json 里的 `--daemon` 参数去掉,由 systemctl 来管理。

    既然 npm 的路径都写死了,为什么不把 node 的路径一起写死呢 …

    ExecStart=/path/to/node /path/to/npm run start

    不过既然都用 systemd 了,不如直接把 ExecStart 的命令改成 npm script 中的 start 对应的命令

    呃,/尴尬

    把 ExecStart 和 ExecStop 改回用绝对路径,PATH 里加上 `/bin`:

    ```
    ExecStart=/home/cqh/git/nvm/versions/node/v10.3.0/bin/npm run start
    ExecStop=/home/cqh/git/nvm/versions/node/v10.3.0/bin/npm run stop
    Environment=/home/cqh/git/nvm/versions/node/v10.3.0/bin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin

    @chenqh 有些发行版不需要加,比如 Arch Linux,它所有 bin 都是在 /usr/bin 里,/bin 只是一个指向 /usr/bin 的链接而已。
