Node.js Heroku Deployment - Fails To Exec Postinstall Script To Install Bower

Question

Deployment of my Node.js MEAN app to heroku fails with the following errors. I can\'t figure out what is wrong with the bower install...

Here is the error message:

Answer 1

I had the same issue. The problem was that in the bower.json file:

{
    "name": "mean",
    "version": "0.1.3",
    "dependencies": {
        "angular": "1.2.8",
        "angular-resource": "latest",
        "angular-cookies": "latest",
        "angular-mocks": "latest",
        "angular-route": "latest",
        "bootstrap": "3.0.3",
        "angular-bootstrap": "0.10.0",
        "angular-ui-utils": "0.1.0"
    }
}

"bower install" is unable to determine the angular version and requires manual intervention to choose the right version:

Unable to find a suitable version for angular, please choose one:
    1) angular#1.2.8 which resolved to 1.2.8 and has mean as dependants
    2) angular#1.2.9 which resolved to 1.2.9 and has angular-cookies#1.2.9, angular-mocks#1.2.9, angular-resource#1.2.9, angular-route#1.2.9 as dependants
    3) angular#>= 1.0.2 which resolved to 1.2.10-build.2176+sha.e020916 and has angular-ui-utils#0.1.0 as dependants
    4) angular#>=1 which resolved to 1.2.10-build.2176+sha.e020916 and has angular-bootstrap#0.10.0 as dependants
Prefix the choice with ! to persist it to bower.json
[?] Answer: 

So Heroku fails when it executes the script.

FIX

Just change the version of angular in your bower.json file:

"angular": "1.2.10",

1.2.9 will also work.
