Re: Installation error of asn1-types

I got this. What shall I do next? ~$ ghc-pkg unregister hourglass ghc-pkg: unregistering hourglass would break the following packages: crypto-pubkey-types-0.4.3 asn1-encoding-0.9.0 asn1-types-0.3.0 (use --force to override) On Sat, Apr 25, 2015 at 2:09 AM, Adam Bergmark wrote:

HI Peng,

Something might have messed up the hourglass-0.2.9 installation. I would try `ghc-pkg unregister hourglass` (`cabal sandbox hc-pkg unregister hourglass` if in a sandbox) and then trying again.

HTH, Adam
