- Exact error message and exit code
  - sh: 1: make: not found
  - npm error code 127
  - The build reports: “process ... npm install did not complete successfully: exit code: 127”

- Failing command/step
  - [4/6] RUN npm install
  - Under this step, npm runs the prepublish script of share@0.7.40, which executes make and fails: “> share@0.7.40 prepublish” followed by “> make”.

- Missing packages or files mentioned
  - make tool is not installed in the base image (node:slim), causing the npm install to fail.

- Version mismatch/info
  - npm reports a patch update: New patch version of npm available! 11.11.0 -> 11.11.1

- Context highlights from Dockerfile
  - COPY package.json package-lock.json* ./
  - RUN npm install
  - The failure occurs because the prepublish step for a dependency requires make, which isn’t present.

Summary of Docker build error

- Exact error message and exit code
  - make: *** No targets specified and no makefile found.  Stop.
  - npm error code 2
  - A complete log of this run can be found in: /root/.npm/_logs/2026-03-17T23_02_36_651Z-debug-0.log
  - Exit code: 2

- Failing command/step
  - [5/7] RUN npm install
  - Inside this step, npm install runs a prepublish script that executes make, which fails due to the missing Makefile:
    - Prepublish script: share@0.7.40 prepublish
    - Command attempted: make

- Missing packages or files mentioned
  - No Makefile present in /app (missing Makefile needed by the prepublish script)
  - The failure arises because the prepublish script attempts to run make without a Makefile

- Version mismatch/info
  - Base image: node:slim (digest shown in Dockerfile)
  - npm reports a patch update available: New patch version of npm available! 11.11.0 -> 11.11.1
  - (No explicit Node version mismatch noted; the issue is the missing Makefile invoked by the prepublish script.)

  - Base image uses node:slim on Debian bookworm (as indicated by apt sources), where the traditional 'python' package is not available.
  - The message indicates Python 2-era package removal and suggests using Python 3 alias: 'python-is-python3'.

- Failing command/step
  - [5/8] RUN npm install

- Missing packages or files mentioned
  - The failure occurs because there is no Makefile in the project directory, causing the prepublish script (shared as share@0.7.40 prepublish) to fail when it runs make:
    - "No targets specified and no makefile found." This indicates a missing Makefile or targets for the make invocation.

- Version mismatch information
  - No version mismatch reported. There is a patch update notice: "New patch version of npm available! 11.11.0 -> 11.11.1" but no mismatch between tool versions is cited.

Summary:

     at FSReqCallback.oncomplete (node:fs:190:21)
- Missing file mentioned: /app/lib/client/index.js
- Exit code: 2 (npm install exit code)
- Context: The error occurs during the prepublish step invoked by npm install:
  "share@0.7.40 prepublish" -> "make" -> "node_modules/.bin/browserify -s sharejs lib/client/index.js -o dist/share.js" fails due to the missing module above.
- Version/compatibility note: No explicit version mismatch indicated. The build uses the base image node:slim; no mismatch reported.

- Missing packages or files mentioned:
  - None explicitly mentioned as missing; the issue is a parse error in the generated dist/share.js during npm install.
- Version mismatch / environment notes:
  - The error occurs during minification with uglify-js, suggesting the code uses ES6 syntax (e.g., getLength() { return getSnapshot().length },) that older uglify-js may not support, indicating a tooling version mismatch.
