I setup Docker on MacOS yesterday, and wanted to run npm and getting: -bash: npm: command not found
What do I need to do to get it working okay? Thx.

npm isn't installed on the image you're using.
You can do either of the following:
Install it via traditional means; dependent on the OS you're using.
Use an image, such as the official node image which will come with it pre-installed.
You could use #2 in a way such as:
docker run node npm -v

@Patrick Please be sure to accept the answer if it answered your question. Cheers!

Thanks. I ran option #2 as shown: MacBook-Air:~ name$ docker run node npm -v Unable to find image 'node:latest' locally latest: Pulling from library/node 85b1f47fba49: Pull complete ... Digest: sha256:7c9099e0f68242387d7755eaa54c287e16cedd3cca423444ca773794f5f1e423 Status: Downloaded newer image for node:latest 5.5.1 But then after MacBook-Air:test-stable name$ npm install random-ext -bash: npm: command not found Why am I still getting command not found?

@Patrick - it looks like it worked! See the
5.5.1 that printed out? That's from running npm -v. When you ran npm install random-ext you're running that on your local machine, not on Docker. If you want to drop into a shell on the Docker machine, run docker run -it node /bin/shPatrick
I saw the 5.5.1 and noticed it installed, but then npm install random-ext didn't run again and I got the same error. Is "docker run -it node /bin/sh" the same as "npm install random-ext" then? Or how do I run it to install random-ext? Thanks.

@Patrick; the last argument of that command is the command you are running in the container. In the first example; we ran
npm -v and then the container exits. If you run /bin/sh as the command (With the -it flags) then you will run /bin/sh which will run the shell interpreter - and now you can interact with the system, but when you finish (crtl+c, type exit, etc.) then again - the container exits. If you want to install commands, do so within the shell; or better yet - codify it into a Dockerfile and build a new image so you can re-use it. |
