Node.js NODE_PATH环境变量

Question

During development I used to WebStorm node_path =. environment variable. I have set up a variable in the launch of the project settings. Now I want to try to run the project on the server, but do not know how to set this variable there. Help solve the problem!

Answer 1

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。

Answer 2

Add

export NODE_PATH=...

to your system environment setting (/etc/profile,~/.bash_profile...), make it works.

or

You can declare dependencies in package.json(project), like this:

{
    ...
    "dependencies": {
        "connect": "~2.0.3",
        ...
    },
    ...
}

and run

npm install

in the same folder instead. Hope it helps.

Answer 3

I would recommend setting the variable right before you run the command like so:

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.

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

For bonus points add it to your start script in package.json like so:

"scripts": {
    "start": "NODE_PATH=src/ node myapp.js"
}

Then in production all you need to do is run: npm start
