I am unable to start Parity, the database migration fails repeatedly. How in Parity on MacOS (1.4.5 already installed) do I eliminate this error so that my Parity will run?

Geth is fine but not running when this occurs.


Open a terminal and remove your blockchain.

rm -rf ~/.parity/906a34e69aec8c0d/*

Resync again with --warp, this only takes a few minutes.

parity --warp

  • It somehow seems it is not. Can you check parity --version if its the same binary linked? – Afr Dec 4 '16 at 15:34
