如何在 heroku 命令行上调用 npm(安装凉亭组件)? [英] How can I invoke npm on heroku command line (to install bower components)?

问题描述

Bower 用于客户端 Javascript 就像 npm 用于服务器端并读取 component.json 文件来识别应该在部署时获取的依赖项，所以我很高兴 heroku 会在 slug 编译时运行它.

Bower is for client side Javascript what npm is for the server side and reads a component.json file to recognize dependencies that should be fetched at deploy time so I'd be happy it heroku would run it at slug compilation time.

不幸的是，我无法从 Heroku 控制台或一次性命令调用 npm 或 bower (heroku run "npm help") (heroku run bash -> npm help)，因为 ruby​​ 的耙子是可能的.我已将 npm 和 node(最新/x 版本)放在我的 package.json 中，但放在引擎部分，而不是依赖项.

Unfortunately I can not invoke npm or bower from a heroku console or one-off command (heroku run "npm help") (heroku run bash -> npm help) as it's possible with ruby's rake. I've put npm and node (latest/x versions) in my package.json but in the engines section, not the dependencies.

我认为这可以通过自定义 node buildpack 来解决，但我认为这有点太繁重了激活如此明显的东西.

I think this could be solved by customizing the node buildpack but I consider this a little too heavy task just for activating something so obvious.

推荐答案

你也可以设置一个 postintall 命令，类似于你的 package.json

You can also setup a postintall command, something like this in your package.json

"dependencies": {
    "bower": "0.6.x"
},
"scripts": {
    "postinstall": "./node_modules/bower/bin/bower install"
}

然后 npm install 也会安装 bower 依赖项.

Then npm install will also install bower dependencies.

优点:一个命令来统治他们.

Pros : one command to rule them all.

缺点:您不必要地将 bower 作为依赖项嵌入.

Cons : you unnecessarily embed bower as a dependency.
