为什么“ apt-get install nodejs -y”不安装npm？

Question

I have the following bitbucket.pipelines.yml :

image: python:3.5.1

pipelines:
  branches:
    master:
      - step:
          script:
            - apt-get update
            - apt-get install nodejs -y
            - npm install
            - npm run build
            - python get-pip.py
            - pip install boto3==1.3.0
            - python s3_upload.py io-master.fromthiscomesthat.co.uk dist io-master

Having installed node, the build then fails trying to run npm :

+ npm install
bash: npm: command not found

I imagine this is because npm is not in the path. Or something. My Ubuntu/UNIX skills are not the best.

How can I add the install to the path?

Update

Ok, after a lot of fiddling my YAML now looks like this:

image: python:3.5.1

pipelines:
  branches:
    master:
      - step:
          script:
            - apt-get update
            - apt-get install lsb-release -y
            - curl --silent https://deb.nodesource.com/gpgkey/nodesource.gpg.key | apt-key add -
            - VERSION=node_5.x
            - DISTRO="$(lsb-release -s -c)" # <--- error here
            - echo "deb https://deb.nodesource.com/$VERSION $DISTRO main" | tee /etc/apt/sources.list.d/nodesource.list
            - echo "deb-src https://deb.nodesource.com/$VERSION $DISTRO main" | tee -a /etc/apt/sources.list.d/nodesource.list
            - apt-get update
            - apt-get install nodejs -y
            - npm install
            - npm run build
            - python get-pip.py
            - pip install boto3==1.3.0
            - python s3_upload.py io-master.fromthiscomesthat.co.uk dist io-master

Now I have a smaller problem. lsb-release is not being found, even though the installer installs it correctly. Is this a path issue?; how can I execute this when I don't know where it's being installed to? It's difficult to debug because it's running in a docker instance on Bitbucket.

Ubuntu contains a version of Node.js in its default repositories that can be used but it only includes the node binary. If you want to install npm you can do it by typing:

apt-get install npm

However, I recommend you to add the PPA (personal package archive) maintained by NodeSource. This will probably have more up-to-date versions of Node.js than the official Ubuntu repositories.

You need to install the PPA to get access to its contents, and then you can install the nodejs package in the same way that you did above.

curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install nodejs

Using this option, the nodejs package contains the nodejs binary as well as npm, so you don't need to install npm separately.
