Root Cause

Git submodule not initialized. Common after cloning a repo with submodules.

generic

Workarounds

  1. 95% success Initialize and update: git submodule init && git submodule update 
    git submodule init && git submodule update

    Sources: https://git-scm.com/docs/git-submodule

  2. 92% success Or clone with submodules included: git clone --recurse-submodules <url> 
    git clone --recurse-submodules

    Sources: https://git-scm.com/docs/git-clone#Documentation/git-clone.txt---recurse-submodules

  3. 90% success Update to latest: git submodule update --init --recursive 
    git submodule update --init --recursive

    Sources: https://git-scm.com/docs/git-submodule

Dead Ends

Common approaches that don't work:

  1. Delete the submodule directory and re-clone the whole repo 75% fail

    git submodule init is much simpler

  2. Copy the submodule code directly into the repo 70% fail

    Defeats the purpose of submodules — lose upstream updates
