将Node.js应用程序部署到Bluemix时如何指定npm版本?

问题描述：

我在package.json中创建了一个运行时依赖项为作用域软件包的node.js应用程序. :

I created a node.js application with runtime dependencies of scoped packages in my package.json:

"dependencies": {
    "@shawnzhu/mybot" : "latest",
    ...
},
"engines": {
    "npm": ">2.0.0",
    "node": "0.10.38"
},

我还有一个自定义.npmrc，它将范围@shawnzhu指向我的私有npm注册表.

I also have a custom .npmrc that points scope @shawnzhu to my private npm registry.

当前，它在部署到heroku(将npm升级到v2.7.x)时有效.但是，cf push到bluemix失败，控制台输出显示:

Currently it works when deploying to heroku, where it upgrades npm to v2.7.x. However, a cf push to bluemix fails with the console output showing:

registry "@shawnzhu/mybot" not found.

查看了整个控制台的输出后，我意识到它使用的是npm v1.4.28，该版本不支持作用域软件包.

After reviewing the whole console output I realized it uses npm v1.4.28 which doesn't support scoped packages.

如何在bluemix中的node.js应用程序中获取npm v2.0.0 +?

How can I get npm v2.0.0+ in a node.js app in bluemix?

在2015年6月15日之前:到目前为止，无法在Bluemix上使用默认的Node.js buildpack.现在，您可以使用社区开源Node.js buildpack:

Before June 15, 2015: This was not possible using the default Node.js buildpack on Bluemix, yet. For now, you can use the community open-source Node.js buildpack:

cf push mynodeapp -b https://github.com/cloudfoundry/nodejs-buildpack

您已经在package.json中正确指定了npm版本，因此它应该适用于社区buildpack.

You've specified the npm version in your package.json correctly, so it should work for the community buildpack.

2015年6月15日之后:Bluemix现已提供IBM Node.js Buildpack的最新版本！您可以在 https:上看到完整的更改: //developer.ibm.com/bluemix/2015/06/15/bluemix-node-js-buildpack-update/

After June 15, 2015: The newest version of the IBM Node.js Buildpack is now available on Bluemix! You can see the full changes at https://developer.ibm.com/bluemix/2015/06/15/bluemix-node-js-buildpack-update/

此buildpack具有通过包含"npm"和"npm"来指定NPM版本的能力.在package.json中的条目，如下所示:

This buildpack comes with the ability to specify NPM versions by including an "npm" entry in your package.json, like so:

"engines": {
    "npm": "xxxxxxx"
},
