cabal: Could not resolve dependencies:
[__0] trying: TeX-my-math-0.202.1.0 (user goal)
[__1] next goal: base (dependency of TeX-my-math)
[__1] rejecting: base-4.14.1.0/installed-4.14.1.0 (conflict: TeX-my-math =>
base>=4.8 && <4.14)
[__1] skipping: base-4.14.1.0, base-4.14.0.0 (has the same characteristics
that caused the previous version to fail: excluded by constraint '>=4.8 &&
<4.14' from 'TeX-my-math')

[__1] fail (backjumping, conflict set: TeX-my-math, base)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, TeX-my-math
