使用`node`启动节点应用程序有效，但使用`/ usr / bin / node`启动它不起作用

Question

我试图将节点应用程序设置为service并启动服务，我需要使用绝对路径来启动节点，这意味着我必须以usr/bin/node来启动它，但是无论如何原因是使用此绝对路径时我的应用程序无法正常工作。

可以工作

root@server:/etc/systemd/system# node /var/www/gwart./mediawiki/extensions/VisualEditor/parsoid/bin/server.js

不起作用

您可能在不同的路径上安装了不同版本的节点，并且您的应用程序可能需要特定版本才能正确运行。考虑将console.log(process.version);添加到脚本的开头，用两个命令运行它，然后比较输出。如果它们是不同的版本，则可能需要将符号链接添加到/usr/bin/node中nvm文件夹中的正确版本。
