cabal install gving errror as LICENSE: openBinaryFile: does not exist (No such file or directory)

I have cabal version:

❯ cabal --version
cabal-install version 3.0.0.0
compiled using version 3.0.0.0 of the Cabal library

Here is what I am doing.

mkdir foo
cd foo
cabal init
cabal install

and I am getting an error:

LICENSE: openBinaryFile: does not exist (No such file or directory)

What I am doing wrong here?

Solution

  • When ran in the manner you describe, cabal init warns that:

    Warning: unknown license type, you must put a copy in LICENSE yourself.

    Without a LICENSE file, certain commands won't work properly (cf., for instance, cabal issue #6744). You should either create a LICENSE file, or pick one of the licenses Cabal knows about by specifying it through the -l option of cabal init.
