I'm following the steps to install ethermint on top of tendermint that are listed on the README on this github page: https://github.com/tendermint/ethermint, but at the step ethermint --datadir ~/.ethermint init setup/genesis.json, then I get the following error: ethermint: command not found
And yes, I installed tendermint previous to my attempted installation of ethermint.
While the solution I figured out for my problem is contained on the GitHub issue page linked above, I also wanted to include it here for the sake of people who have the same issue.
OK, so I fixed the problem, and it was so infuriating. It turns out that whenever I opened a terminal, then the go version would default to go1.6, even if I was in the go1.8.3 directory. To solve the error, you need to delete the old go version off of your computer, and then use gvm to set the right go version. Thanks to everyone who helped me solve this issue.
