You wrote this Dockerfile line:

RUN npm install

but the build fails with 'npm: command not found'. What is the likely cause?

Cnpm install should be run outside the Dockerfile.

DThe WORKDIR was not set before RUN.

Step-by-Step Solution

Solution:

Step 1: Understand error meaning
'npm: command not found' means npm is missing in the container environment.
Step 2: Check base image
If base image lacks Node.js/npm, RUN npm install fails; syntax and WORKDIR do not cause this error.
Final Answer:
The base image does not have Node.js and npm installed. -> Option B
Quick Check:
npm missing = base image lacks Node.js [OK]

Quick Trick: Use node-based image to have npm available [OK]
