I'm trying to run a node script with Crone and even though I think I'm using the absolute path in every step of the way, I am still getting a "no such file or directory" when trying to read a JSON file while running the script from Cron.
The interesting thing is that everything works fine when I run it from the shell!
[/]$ /usr/local/bin/node /root/Main/email.js
^^ This works fine!
However when I run with crontab like this:
0,29 * * * * /usr/local/bin/node /root/Main/email.js
I get this printed to the log:
fs.js:438
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
^

at node.js:906:3
The line of code on my node sketch that is throwing the error is this one:
var file = fs.readFileSync('root/Main/email.json', 'utf8')
What am I missing? Isn't this the absolute path? Why is it only working directly from the shell!

I managed with couple of steps
which node: /Users/xyz/.nvm/versions/node/v12.18.2/bin/node
I included that to path variable inside bash_profile:
export PATH="/Users/xyz/.nvm/versions/node/v12.18.2/bin:$PATH"
Worked like charm
i following an express.js tutorial andd after some code and functionalities with api requests i followed exactly how he changed the code that handles these requests into a seperate js file in another folder just to clean up the code but after i did that this error showed up
i tried changing the file name , i tried removing the node-modules folder and running npm install again and i tried installing the module with the issue

i expect nodemon to save the changes and work just fine with no errors just like what happened in the tutorial
It appears the error is probably coming from this line of code and it's telling you that it can't find the '/routes/api/members' module file.
And, this would not be working because you're trying to load a local module without a proper path name. If no path is specified, then it tries to load a global or built-in module. If that module is in the current directory, then you should use the correct path:
const yourModule = './routes/api/members';
I'm building an os-agnostic npm package that uses a few submodules from within itself. On my mac, I require modules using app-root-path like so:
var path = require('path');
var appRoot = require('app-root-path');
var packageJson = JSON.parse(fs.readFileSync(path.join(appRoot.path, 'node_modules', 'myModule', 'package.json')).toString());
and this works as expected.
But it fails on linux (and I assume it'd fail on windows too) because the app-root-path package above doesn't return correct path the same way it does on mac.
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);

Why is this?
How can I make it work without worrying about host OS (mac / linux / windows)?
Note, I did use the answers/tips on this question on stackoverflow.
In the requireJS site they said that We can generate the r.js using
"node dist.js"
Source http://requirejs.org/docs/node.html
for me it does make error :

Any help ? thank you
Sounds like there might an error in your version of dist.js / fs.js.
Could you try running node dist.js on the original version of the r.js repository here?
If that works, then you'll have to do further troubleshooting on your r.js file to get to the bottom of the issue.
Otherwise, it's an issue with your development environment, in which case you can post the errors here.
I have the module underscore installed globally with npm. if I run the script
/usr/local/bin/node /home/olmo/project/processDrivesMultiUser.js
it will run ok wherever I am on the path, but if I run a cronjob like this:
3,18,33,48, * * * * /usr/local/bin/node /home/olmo/project/processDrivesMultiUser.js
I get this error:

somehow it can't find the module underscore if it runs via cron. I made the cron entry for the same username I'm using to run the script manually.
any ideas?
I could find the answer based on the comment by mu is too short.
I modified the crontab to include the environmental variable NODE_PATH
3,18,33,48, * * * * export NODE_PATH=/usr/local/lib/node_modules/ && /usr/local/bin/node /home/olmo/project/processDrivesMultiUser.js
now I'm able to use modules in node.js if called by cron.
