当使用sdk-for-nodejs buildpack将应用程序部署到Bluemix时，如果我不希望它运行npm install.我该如何阻止它? [英] When deploying an app to Bluemix using the sdk-for-nodejs buildpack, it's running npm install when I don't want it to. How can I stop it?
问题描述
我正在使用Bluemix DevOps Pipelines将Node.js应用程序作为Cloud Foundry应用程序部署到Bluemix.它使用 sdk-for-nodejs 内置(尽管我没有指定，但它正在检测package.json文件).
I'm using Bluemix DevOps Pipelines to deploy a Node.js app to Bluemix as a Cloud Foundry app. It is using the sdk-for-nodejs buildback (although I haven't specified that, it's detecting the package.json file).
上架该应用程序需要很长时间.查看日志，这是因为它似乎正在运行npm install.但是，我已经设置好管道，以便在更早的阶段调用npm install，并且要部署的构建工件已经包含已安装的node_modules，因此，如果我必须重新安装它，它应该很快，因为它不必再次安装所有模块.
It takes a long time to stage the app. Looking at the logs, this is because it appears to be running npm install. However, I have set up my pipeline so that npm install is called in an earlier stage, and the build artifact that is to be deployed already contains the installed node_modules, so if I have to restage it should be quick, as it shouldn't have to install all the modules again.
这是我的管道用于部署的命令:
This is the command that my pipeline is using to deploy:
cf push "${CF_APP}" -c "npm run start:prod"
我的Procfile也包含相同的命令:
My Procfile also contains the same command:
web: npm run start:prod
node: npm run start:prod
(我在第二行和第二行都尝试过.我认为下面的日志是同时包含两行的.)
(I've tried it both with and without the second line. I think the logs from below were when it contained both lines.)
事实上，在部署日志即将结束时，它会显示
And indeed towards the end of my deployment logs it says
App mcp-server was started using this command `npm run start:prod`
我的package.json文件中的脚本未运行npm install:
That script in my package.json file does not run npm install:
"scripts": {
...
"start:prod": "cross-env NODE_ENV=production node index.js",
使它看起来像在重新安装模块的日志是:
The logs that make it look like it's re-installing the modules are:

特别值得注意的是以下几行:
Of particular note are the lines:

...
Completed: 99.9% (78.2mb / 78.2mb)
在这里我已经省略了100多个行，而这似乎是在缓慢地安装一些东西.
where I've omitted well over 100 lines where it seems to be installing something very slowly.
还有:
> npm run clean && npm run build
> myapp@2.0.0 clean /tmp/app
> myapp@2.0.0 build /tmp/app
> cross-env NODE_ENV=production webpack --config webpack.config.js
这些是我的应用程序中的脚本，我真的不想在部署时运行.
which are scripts from my app that I really don't want to be running at deployment time.
我已经尝试告诉它运行npm run start:prod-如何阻止它运行这些安装步骤?
I've already tried to tell it to run npm run start:prod - how can I stop it from running these install steps?
推荐答案
看着buildpack代码，我看不到禁用npm install的标志.
Looking at the buildpack code, I don't see a flag to disable npm install.

选项1
创建一个没有列出依赖项的package_nodependencies.json文件.在构建步骤使用常规package.json运行npm install之后，删除package.json并将package_nodependencies.json重命名为package.json.
Create a package_nodependencies.json file with no dependencies listed. After your build steps runs the npm install using your regular package.json, delete the package.json and rename package_nodependencies.json to package.json.
rm package.json && mv package_nodependencies.json package.json
npm install现在应该很快.确保您的.cfignore文件中没有node_modules
npm install on cf push should now be quick. Be sure that you don't have node_modules in your .cfignore file
选项2
将所有依赖项移动到package.json中的devDependencies.在构建期间，运行不带PRODUCTION的npm install
Move all your dependencies to devDependencies in package.json. During your build, run npm install without PRODUCTION
NODE_ENV =开发npm install
NODE_ENV=development npm install
