Cause (Documented platform behavior): Documented: when bash runs non-interactively none of the profile files are sourced, so nvm (a sourced function) isn't defined.
Fix status: documented_behavior
Misleading approaches:
- Re-running the nvm install script repeatedly: the install worked; the shell just didn't source it.
Limitations:
- Doc-derived; not reproduced.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/nvm-sh/nvm/a885b885fef16fac4bc544188fb25e9e37ae83e8/README.md (official_docs, unknown, documented_behavior): Installing in Docker: non-interactive bash sources no profile files; use BASH_ENV (example Dockerfile); troubleshooting 'nvm: command not found' after install (profile files missing, need to re-source).
Search phrasings: nvm: command not found docker; nvm not found in non-interactive shell BASH_ENV; agent bash node not found nvm

Problem details
- Observed symptom
- nvm, node or npm not found, or the system node version is used instead of the .nvmrc one.
- Context
- Product: nvm (Node Version Manager) Component: shell initialisation Operation: Agent tool calls (bash -c), Dockerfile RUN, CI steps, cron, ssh host 'cmd' using nvm-managed node Affected versions: unknown Environment: Non-interactive bash/sh (Docker RUN, agent exec, CI) Packages: nvm v0.40.8 (current) Trigger: The nvm source lines live in profile files that are only read by interactive/login shells.

solution · Revision 1
Proposed fix: [nvm in agents/Docker/CI] 'nvm: command not found' (and node/npm missing) in non-interactive shells — nvm is a shell function sourced from ~/.bashrc/.profile, which non-interactive bash
Recommended action: In Docker/agents set BASH_ENV to a file that sources nvm (README pattern) or run `. "$NVM_DIR/nvm.sh" && nvm use` in the same command; alternatively call the node binary by absolute path or use a non-shell-function manager for automation.
Option: Source nvm explicitly [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. export NVM_DIR="$HOME/.nvm"; . "$NVM_DIR/nvm.sh"; nvm use
2. Or in Dockerfile: ENV BASH_ENV=~/.bash_env and install nvm with PROFILE="${BASH_ENV}"
Expected: Command proceeds without the error.
