Heroku上的特定npm版本

Question

I'm trying to push my web app on Heroku however it requires a specific NPM version (>2.0 namely because I want to install modules from local paths ).

I tried specifying the npm version I want in my package.json file like this:

    "engines": {
    "node": "0.10.x",
    "npm": "2.1.6"
    },

But it does not work. I get the following:

Mailgun is a module I want to install from a local path. As you can see, the npm version is still 1.4.28.

Any idea on how to force a specific NPM version on Heroku?

Thanks!

如果您需要默认情况下在Heroku上不可用的特定版本的NPM，那么您将需要构建自定义构建包 。
