Assuming it's a UNIX or Mac OS X server, use export NODE_PATH=and append the path you want.
假设它是 UNIX 或 Mac OS X 服务器，请使用export NODE_PATH=并附加所需的路径。

I would recommend setting the variable right before you run the command like so:
我建议在运行命令之前设置变量，如下所示：
NODE_PATH=src/ node myapp.js
This way the variable is set when needed. This is preferable unless you really need to change the path with different versions of your deployment.
这样，在需要时设置变量。除非您确实需要使用不同版本的部署更改路径，否则这是更可取的。
If on windows, you can use this lil package to get the effect to work so it is consistent across dev and prod: win-node-env
如果在 Windows 上，您可以使用这个 lil 包来获得效果，使其在 dev 和 prod 之间保持一致：win-node-env
For bonus points add it to your start script in package.jsonlike so:
对于奖励积分，将其添加到您的启动脚本中，package.json如下所示：
"scripts": {
"start": "NODE_PATH=src/ node myapp.js"
}
Then in production all you need to do is run: npm start
然后在生产中你需要做的就是运行： npm start
