I’m having trouble deploying my application on Heroku. It seems like Heroku is using an outdated version of npm (1.0.94), which is resulting in compatibility issues with my dependencies.
I need a package that requires node version 0.6.x or later, but unfortunately, the npm version on Heroku is based on node 0.4.7. This conflict is preventing me from completing the deployment.
Has anyone else faced this challenge? What are some possible solutions or workarounds to overcome this version issue during deployment on Heroku?
Here’s the error message I received:
Installing dependencies using npm 1.0.94
npm ERR! Version conflict

Had this exact problem a few months ago with my Node.js app. Heroku’s buildpack was stuck on an old Node version. Fixed it by adding an “engines” field to package.json - something like “engines”: {“node”: “0.6.x”, “npm”: “1.1.x”}. This forces Heroku to use your specified version. Make sure your local environment matches what you’re specifying or you’ll get weird surprises. Clear your npm cache, test locally, then push to Heroku. Worked perfectly for me with no code changes needed.
First, check your Heroku buildpack. Cedar stack handles newer Node versions automatically, but older stacks default to legacy versions. Set it explicitly with heroku buildpacks:set heroku/nodejs. You can also create a .nvmrc file in your root directory with just the version number like 0.6.0 - this tells Heroku which Node version to install. I’ve hit similar issues migrating legacy apps. Sometimes the deployment cache gets corrupted. Try heroku repo:purge_cache before your next deploy to force a fresh build.
check if ur usin the bamboo stack - thats probably why its defaultin to node 0.4.7. bamboo is deprecated n stuck on old versions. migrate to cedar stack first, then specify ur node version in package.json engines field like others mentioned. had the same issue last year n stack migration fixed it instantly.
