Thanks for opening a docs PR, Elisabeth Rulke (@erulkey)! When it's ready for review, please add the relevant reviewers:
|
The Vercel Sandbox Python examples call Sandbox.create() with no runtime,
which defaults to node24 (Vercel's JavaScript runtime), then run Python.
Following them as written fails: python/pip/uv are only present on the
python3.13 runtime.
Reproduced live (langchain-vercel-sandbox 0.0.1 + vercel 0.5.9):
Sandbox.create() -> node24
backend.execute("python --version") => "bash: python: command not found", exit 127
Sandbox.create(runtime="python3.13")
backend.execute("python --version") => "Python 3.13.1", exit 0
Adds runtime="python3.13" to the 7 Vercel Python snippets. The JS example
already sets runtime: "node24" and runs TypeScript, so it is unaffected.

What
The Vercel Sandbox Python examples create the sandbox with
Sandbox.create()and noruntime, which defaults tonode24(Vercel's JavaScript runtime). The same examples then run Python (python --version, "run pytest", etc.), so following them as written fails.Repro (live)
Running the example verbatim with
langchain-vercel-sandbox0.0.1 +vercel0.5.9:With the one-line change:
Per Vercel's docs,
python3.13is the only runtime that shipspython/pip/uv; thenode*runtimes shipnpm/pnpmonly (runtimes docs). Vercel's own Python example usesruntime: "python3.13".Change
Adds
runtime="python3.13"to the 7 Vercel Python snippets:src/oss/python/integrations/sandboxes/vercel.mdx(2)src/oss/deepagents/sandboxes.mdx(3)src/snippets/sandboxes-basic-tabs-py.mdx(1)src/snippets/deepagents-sandbox-basic-py.mdx(1)The JS example already sets
runtime: "node24"and runs TypeScript (verified:node hello.tsworks on node24), so it's unaffected.
