"dyld" errror When you encounter the above error, you should do the following *. install node using the command "brew install node" *. update/upgrade brew using "brew upgrade" At this point, the error of "dyld not found" will be resolved 2. InvalidArgumentException: In case you see this error in your browser after running "php artisan serve", then you should do the following to resolve the problem *. cd storage/ *. mkdir -p framework/{sessions,views,cache} *. chmod -R 775 framework EXPLANATIONS: 1. "cd storage" will change your current directory to the storage directory 2. "mkdir -p framework/{sessions,views,cache}" will create the folder named "framework".
