Question

Fatal error: Uncaught Error: Class 'Composer\CaBundle\CaBundle' not found in

I'm using it for the first time, so checked the TwitterOAuth.php file and line 572 then vscode says the CaBundle is undefined Type Undefined type 'Composer\CaBundle\CaBundle'. , I tried downloading the file over and over again but the same error.

Answer 1

I had the exact same problem following the instructions on here.

It turns out I wasn't including the right autoload. For those coming across the same problem:

1. Install composer locally on your directory as per these instructions.
2. Run php composer require abraham/twitteroauth.
3. Run php composer install.
4. Make sure to include the right path to the composer autoloader file, not the package autoloader, in your PHP code require "vendor/autoload.php";.
5. In each file that you will be using the package, don't forget to include the line use Abraham\TwitterOAuth\TwitterOAuth as TwitterOAuth;, so that you can use $foo = new TwitterOAuth();

I hope this helps those who might be new to composer like me.
