I followed the instructions on lecture one - part 3 and I was trying to start week 1 project. When I run cabal build got the following error:
[nix-shell:~/plutus-pioneer-program/code/week01]$ sudo cabal build
Warning: The build command is a part of the legacy v1 style of cabal usage.
Please switch to using either the new project style and the new-build command
or the legacy v1-build 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...
Warning: solver failed to find a solution:
Could not resolve dependencies:
[__0] trying: plutus-pioneer-program-week01-0.1.0.0 (user goal)
[__1] next goal: base (dependency of plutus-pioneer-program-week01)
[__1] rejecting: base-4.12.0.0/installed-4.1... (conflict:
plutus-pioneer-program-week01 => base^>=4.14.1.0)
[__1] fail (backjumping, conflict set: base, plutus-pioneer-program-week01)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: plutus-pioneer-program-week01, base
Trying configure anyway.
Configuring plutus-pioneer-program-week01-0.1.0.0...
cabal: Encountered missing dependencies:

Could not resolve dependencies and cabal: Encountered missing dependencies is the errors here as far I can understand. I tried again by running cabal update and then cabal build but again I get the same error(s) that I described above. Any ideas? What am I doing wrong?
