Unsupported protocol with sparse registry #11726
Description
Problem
When using sparse registry, cargo reports Unsupported protocol error.
HTTP multiplexing defaults to true at
cargo/src/cargo/sources/registry/http_remote.rs
Lines 223 to 225 in 39c13e6
cargo/src/cargo/sources/registry/http_remote.rs
Lines 555 to 556 in 39c13e6
cargo is dynamic linked to
libcurl, however libcurl from Apple in macOS 10.12.6 has no HTTP2😳
Steps
$ env CARGO_REGISTRIES_CRATES_IO_PROTOCOL=sparse rustup run nightly cargo install oris
Updating crates.io index
error: failed to query replaced source registry `crates-io`
Caused by:
[1] Unsupported protocol
Possible Solution(s)
- fallback to
HTTP/1.1 - replace the ambiguous error message
- maybe add suggestion: set
CARGO_HTTP_MULTIPLEXINGtofalseiflibcurldoesn't supportHTTP/2
- maybe add suggestion: set
- static link to
libcurl
