Lesson 5: ganache-cliFileNotFoundError: [Errno 2] No such file or directory: 'ganache-cli'

[CrispyButter]

Can anyone help me understand why ganache-cli is not found when trying to deploy a script? I have ganache cli and for hours haven't been able to get past the Filenotfounderror.

Hello @CrispyButter I would pretty much say that the yarn packages aren't added to the env variables so they are not recognized as commands. I recommend you to install npm using brew or nvm, use this link as reference.

I hope this info, might help.
