Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: reflex-dom-0.6.1.1 (user goal)
[__1] trying: reflex-dom:-use-warp
[__2] trying: reflex-dom:-wasm32
[__3] trying: jsaddle-webkit2gtk-0.9.8.1 (dependency of reflex-dom -use-warp
-wasm32 +/-webkit2gtk)
[__4] next goal: webkit2gtk3-javascriptcore (dependency of jsaddle-webkit2gtk)
[__4] rejecting: webkit2gtk3-javascriptcore-0.14.4.3,

webkit2gtk3-javascriptcore-0.14.4.0, webkit2gtk3-javascriptcore-0.14.3.0,
webkit2gtk3-javascriptcore-0.14.2.1 (conflict: pkg-config package
webkit2gtk-4.0==1.1.15 || >1.1.15, not found in the pkg-config database)
[__4] fail (backjumping, conflict set: jsaddle-webkit2gtk,
webkit2gtk3-javascriptcore)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: webkit2gtk3-javascriptcore,
jsaddle-webkit2gtk, reflex-dom, reflex-dom:use-warp, reflex-dom:wasm32
Try running with --minimize-conflict-set to improve the error message.
