error at run ./ganache

[snackyoung]

sudo: ./ganache: command not found

Then I change the ganache file to the ganache.sh and run:
./ganache.sh: 3: ./ganache.sh: /home/snack/eth-atomic-swap/node_modules/.bin/ganache-cli: not found

Then I npm install -g ganache-cli into ../node_module/.bin/ganache-cli, it says:

problem solved. I have other tasks occupied the port 8545.

[0x31]

If anyone else has this issue, ganache may already be running (so you can run truffle test), or, if you are running another process using port 8545 (such as an ethereum node), you will have to run ganache on a different port.

To do so, edit truffle.js and on line 5 change 8545 to 8546. Run ganache-cli --port 8546 and then in a different terminal run truffle test.
