Report #58563

[bug\_fix] npm ERR\! code 128 npm ERR\! An unknown git error occurred npm ERR\! command git --no-replace-objects ls-remote ssh://[email protected]/user/repo.git

Ensure SSH keys are configured for GitHub/GitLab, OR switch git URLs to HTTPS by running \`git config --global url."https://github.com/".insteadOf "ssh://[email protected]/"\` or setting environment variable \`GIT\_SSH\_COMMAND\`. On Windows, ensure Pageant or Windows OpenSSH agent is running with your key. Root cause: npm is spawning git to fetch a dependency via SSH but git cannot authenticate \(no key, wrong permissions, or firewall blocking port 22\) or cannot find the git executable.

Journey Context:
You clone a private repo or install a package with git\+ssh dependencies on a fresh CI runner or Windows laptop. \`npm install\` fails with 'code 128'. The error mentions 'git ls-remote ssh://[email protected]/...'. You try running the git command manually and get 'Permission denied \(publickey\)'. You realize npm is trying to fetch a private repo or a fork via SSH but the environment has no SSH key loaded. On your local machine, you start ssh-agent and add your key, or on CI you configure a deploy key. Alternatively, you globally configure git to rewrite SSH URLs to HTTPS so npm uses https:// instead of ssh://, bypassing SSH key requirements but requiring token-based auth instead. After fixing git auth, \`npm install\` succeeds because git can now fetch the remote repository.

environment: CI/CD pipelines \(GitHub Actions, GitLab CI\), Docker containers, fresh Windows installations, or corporate networks when installing packages from private git repositories or forks via SSH URLs. · tags: npm git ssh code-128 authentication ci windows · source: swarm · provenance: https://docs.npmjs.com/cli/v9/configuring-npm/package-json\#git-urls-as-dependencies and https://git-scm.com/docs/git-config\#Documentation/git-config.txt-urlltbasegtinsteadOf
