Do these package versions work together and on your runtime?
Do these package versions work together and on your runtime? Give up to 20 npm or PyPI packages (exact versions, ranges or latest) plus your Node or Python version; each package's engines, peer dependencies or Requires-Python / Requires-Dist are checked against the others and the runtime, with conflicts explained and end-of-life runtimes flagged.
