Warning: The install command is a part of the legacy v1 style of cabal usage.

Please switch to using either the new project style and the new-install
command or the legacy v1-install alias as new-style projects will become the
default in the next version of cabal-install. Please file a bug if you cannot
replicate a working v1- use case with the new-style commands.

Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: stdio-0.2.0.0 (user goal)
[__1] trying: stdio:-integer-simple
[__2] rejecting: stdio:-no-pkg-config (conflict: pkg-config package
libuv>=1.14, not found in the pkg-config database)
[__2] rejecting: stdio:+no-pkg-config (manual flag can only be changed
explicitly)
[__2] fail (backjumping, conflict set: stdio, stdio:integer-simple,
stdio:no-pkg-config)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: stdio, stdio:integer-simple,
stdio:no-pkg-config, integer-simple
