First of all, I have trouble installing avrdude via Homebrew because of some network problems. So I download it manually from its website.
However, after I unarchive the avrdude-7.0.tar.gz file I just downloaded, I can find no bin directory there. It's unusual.
Then, I added its directory to my system PATH by export PATH=$PATH:/Users/myUserName/Developer/bin/avrdude-7.0/bin/. But when I tried to use avrdude in Terminal after I restarted my computer, It says zsh: command not found: avrdude.
How can I make it works?
Apparently you downloaded the source archive of the tool, not the executable software.
Now you have two options:
Download the binary executable.
Compile the tool yourself. Make sure you understand how to do this.
