I'm trying to run Heroku applications locally via 'heroku local,' but a missing module error is occurring in the Heroku CLI. Is this a Heroku bug that just needs to be reported or is there something wrong with how things have been setup on my machine (mac)? Any suggestions are appreciated.
In order to ensure my application isn't the problem, I've been debugging this issue with the node application Heroku provides in its getting started guides. Meaning, it already has a Procfile that can be run using default settings.
Things I've tried:
Re-install node modules for both application and CLI
Re-install the Heroku CLI
Here's the error:
node-js-getting-started [master] :> heroku local
Error: Cannot find module '../../load-foreman-procfile'
at Object.<anonymous> (/usr/local/Cellar/heroku/7.26.1/libexec/node_modules/#heroku-cli/plugin-local/lib/commands/local/index.js:5:18)
The file for the route above requires a 'load-foreman-procfile' like so:
const Procfile = require('../../load-foreman-procfile');
That require path doesn't lead to a to file by that name. In fact, this is the only reference to 'load-foreman-procfile' I can find in '/usr/local/Cellar/heroku/7.26.1'.
Rather than the error code above, I would expect heroku local to yield a running local server started via my Procfile.
I got the same error running heroku-cli v7.26.0. I switched to their edge channel (currently v7.26.2) and heroku local worked for me after that.
like #sophon mentioned - updating from v7.26.0 to v7.26.2 solved this for me. heroku update on mac did the trick.

I am getting an error in the screen shot bellow deploying a node.js app on heroku saying that the buildpack was unable to detect a node.js codebase
I set the build pack, the package.json is at the root level as is the app.js file

Not sure what I am doing wrong - thanks!!
The error is clear:
A Node.js app on Heroku requires a package.json.
In the files listed below, you can see that the package.json file is missing. You have to commit it and repush your code to Heroku.
This works perfectly fine locally, I've been looking through all of heroku's node deployment related documentation but haven't been able to find the solution there.
This is my terminal view after building with the first error:
terminal log after running 'git push heroku master
terminal log after running 'heroku logs'
I'm trying to deploy my Django app on Heroku, that makes use of the Blockchain.info API V2 (https://github.com/blockchain/service-my-wallet-v3) and thus needs to run blockchain-wallet-service in the background, which in turn needs Node.js and npm installed.
On localhost, I have used this API successfully by running the service on my own machine, but I'm having trouble deploying to Heroku. Firstly, I assume I will need to run the service on a separate dyno, and that I will need node and npm installed on my instance.
Can someone tell me how to achieve this? I'm new to more advanced features of Heroku, I've tried to use the nodejs buildpack but I doubt this is the correct way. There is also this: https://elements.heroku.com/buttons/kmhouk/service-my-wallet-v3 which I've deployed as a separate app but I've failed to merge it in some way to my Django app.
Any help is much appreciated!
I had this exact same issue, bro, and i finally got some light in the end of the tunnel.
I've cloned the https://github.com/blockchain/service-my-wallet-v3 repository and deployed it to heroku and made some changes on "package.json" file. The problem is that (in heroku) you need to declare the dependencies on package file. I've added these lines:
"dependencies": {
"blockchain-wallet-service": "~0.22.4",
}
and a script to test in the deploy:
"scripts": {
"postinstall": "blockchain-wallet-service -V"
}
Also, by cloning this repository, i needed to add this line too:
"license" : "(ISC OR GPL-3.0)",
hope it works for you
I created a new Node.js app on Bluemix this morning and downloaded the boilerplate code. I worked on it locally and then pushed it up. On Bluemix, it refuses to start. The error according to the logs is:
Instance (index 0) failed to start accepting connections
So I Googled for that, in every case where I found the result, the answer was that my application was trying to use a specific port instead of letting Bluemix set it.
Ok, but I'm setting the host/port with the exact code the boilerplate uses:
var appEnv = cfenv.getAppEnv();
// start server on the specified port and binding host
app.listen(appEnv.port, function() {
// print a message when the server starts listening
console.log("server starting on " + appEnv.url);
});
So if this is incorrect, it means the code Bluemix told me to download itself is incorrect as well, and I can't imagine that is the issue.
To identify whether cfenv is at fault, I've tested that piece of code with a number of more complex Node.js apps I have, and they work perfectly on Bluemix.
That message can also come when an application you've deployed to Bluemix fails to start at all. Here's a few things you can do to troubleshoot your Node.js application on Bluemix.
Tail logs in another terminal while pushing with "cf logs
". Inspect logs after the failure to see if something
failed during the staging process.
Check that your start command in one of two recommended places, scripts.start in package.json or in a Procfile with web: node <start-script>.
Check that your application works locally. First (optional), create a .cfignore file with "/node_modules" in it, so that when you push the app to Bluemix, CF CLI doesn't push your entire folder of node_modules (as they will be installed dynamically). Next, wipe out your node_modules directory and do an npm install --production followed by npm start (or your custom start command). This is what Bluemix does when trying to start your application, so you should double check that it works locally.
Finally, try bumping up your memory, although this is very unlikely that this is why your application fails to start.
So, I'm currently following this tutorial: https://devcenter.heroku.com/articles/nodejs to start a simple Node.js app. I've got to the part where foreman is used to run the app locally (under Declaring process types with Procfile), and I'm getting an error telling me that the Procfile does not exist. My Procfile is in the same directory as my code, etc. All of the steps up till now have been fine. I skipped past this part in the tutorial to try and run the application on Heroku, but this line heroku ps:scale web=1 under Visit your application tells me that there is "No such type as web"... I'm using Windows to develop my app. Any help would be much appreciated. :-)
EDIT: web: node web.js is the contents of the Procfile, and I'm following the tutorial so I assume it's being committed... could you check the tutorial please and tell me if it is?
I had also received the Procfile does not exist error. The issue with mine was that I had left the '.txt' extension on the file. Once I removed the file extension and ran the foreman start it worked perfectly, hope this help =)
