1. Hello,

   I was just wondering if you could perhaps show what your .zshrc file looks like? I might have removed a couple of lines from the file and added the new line (export PATH…) in the wrong location.

   Thanks!
   Kind regards,
   Tin

   1. Hello,
      This is my .zshrc filr:

      # >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/opt/homebrew/Caskroom/miniforge/base/bin/conda' 'shell.zsh' $
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/opt/homebrew/Caskroom/miniforge/base/etc/profile.d/conda.sh" ]; t$
. "/opt/homebrew/Caskroom/miniforge/base/etc/profile.d/conda.sh"
else
export PATH="/opt/homebrew/Caskroom/miniforge/base/bin:$PATH"
fi
fi
unset __conda_setup
# <<< conda initialize <<<

2. Hi,

   I tried /usr/bin/ruby -e “%(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)” but it didn’t do anything and when I typed brew install miniforge, it said cannot find brew command?

   Thank you

3. Hi,

   My .zshrc file looks like:

   # >>> conda initialize >>>
   # !! Contents within this block are managed by ‘conda init’ !!
   __conda_setup=”$(‘/Users/seankoh/opt/anaconda3/bin/conda’ ‘shell.zsh’ ‘hook’ 2$
   if [ $? -eq 0 ]; then
   eval “$__conda_setup”
   else
   if [ -f “/Users/seankoh/opt/anaconda3/etc/profile.d/conda.sh” ]; then
   . “/Users/seankoh/opt/anaconda3/etc/profile.d/conda.sh”
   else
   export PATH=”/Users/seankoh/opt/anaconda3/bin:$PATH”
   fi
   fi
   unset __conda_setup
   # <<< conda initialize <<<

   How do I implement this code (export PATH=$PATH:/opt/homebrew/bin) as you said?

   Thank you for your help in advance.

5. Hello,

   I have followed your tutorial (thank you) and everything went smoothly and uneventful until I try to run an application.

   I get this (see below) error (my application is called ‘Camera’ and is supposed to take continuous shots from the computer camera and show them in a JFrame on the screen).

   I use java 17 on a MacBook Pro (M1)

6. Hi, thanks a lot for the tutorial!
   I’m trying to follow your instructions, but when running the cmake command I immediately get the error

   CMake Error: The source directory “/Users/cdemasi/projects/opencv-4.5.0/build/

   even if I’m literally inside the opencv-4.5.0/build folder.
   Any clues why?

7. Hmm it looks like your site ate my first comment (it was super long) so I guess I’ll just sum it up what I had written and say,
   I’m thoroughly enjoying your blog. I as well am an aspiring
   blog writer but I’m still new to everything.

   Do you have any points for inexperienced blog writers? I’d definitely appreciate it.
