Hello!

I followed the tutorial at https://youtu.be/_aCyR8XJcws?t=528 and ran
source setup_env.sh.

I encountered the error setup_env.sh:40: = not found.

I couldn’t find any related topics in the forums. How should I resolve this issue?

I found that this error occurs when using oh-my-zsh in the terminal, but it works fine when using the native bash terminal on the Raspberry Pi.

Is there a solution to this issue?

Thank you for your response.

I’ve modified line 40 of the setup_env.sh script, changing the double equals sign to a single equals sign, so that it can be executed under zsh.

Before modification:

if [ "$TAPPAS_VERSION" == "$version" ]; then

After modification:

if [ "$TAPPAS_VERSION" = "$version" ]; then
