## Summary Previously, we assumed that local indexes only referenced local files. However, it's fine for a local index (like, a `file://`-based Simple API) to reference a remote file, and in fact Pyodide operates this way. Closes https://github.com/astral-sh/uv/issues/14227. ## Test Plan Ran `UV_INDEX=$(pyodide config get package_index) cargo run add anyio`, which produced this lockfile: ```toml version = 1 revision = 2 requires-python = ">=3.13.2" [[package]] name = "anyio" version = "4.9.0" source = { registry = "../../../Library/Caches/.pyodide-xbuildenv-0.30.5/0.27.7/xbuildenv/pyodide-root/package_index" } dependencies = [ { name = "idna" }, { name = "sniffio" }, ] wheels = [ { url = "https://cdn.jsdelivr.net/pyodide/v0.27.7/full/anyio-4.9.0-py3-none-any.whl", hash = "sha256:e1d9180d4361fd71d1bc4a7007fea6cae1d18792dba9d07eaad89f2a8562f71c" }, ] [[package]] name = "foo" version = "0.1.0" source = { virtual = "." } dependencies = [ { name = "anyio" }, ] [package.metadata] requires-dist = [{ name = "anyio", specifier = ">=4.9.0" }] [[package]] name = "idna" version = "3.7" source = { registry = "../../../Library/Caches/.pyodide-xbuildenv-0.30.5/0.27.7/xbuildenv/pyodide-root/package_index" } wheels = [ { url = "https://cdn.jsdelivr.net/pyodide/v0.27.7/full/idna-3.7-py3-none-any.whl", hash = "sha256:9d4685891e3e37434e09b1becda7e96a284e660c7aea9222564d88b6c3527c09" }, ] [[package]] name = "sniffio" version = "1.3.1" source = { registry = "../../../Library/Caches/.pyodide-xbuildenv-0.30.5/0.27.7/xbuildenv/pyodide-root/package_index" } wheels = [ { url = "https://cdn.jsdelivr.net/pyodide/v0.27.7/full/sniffio-1.3.1-py3-none-any.whl", hash = "sha256:9215f9917b34fc73152b134a3fc0a2eb0e4a49b0b956100cad75e84943412bb9" }, ] ```
