CURIO

It suffers me a lot. It takes a lot of time from me to research and solve the problem. The problem was very simple. I have faced the problem and solved it. Main problem was select2 doesn't get ajax.googleapis cdn. So, before the jQuery code I have loaded the cdn and it works fine now. Firstly, the code was     <script>         $(document).ready(function() {             $('.js-example-basic-multiple').select2();         });     </script> The problem is looked like the picture below Now after adding the cdn before the script tag. it has been solved the problem and the code looks like below     <script src="https://code.jquery.com/jquery-3.4.1.js" integrity="sha256-WpOohJOqMqqyKL9FccASB9O0KwACQJpFTUBLTYOVvVU=" crossorigin="anonymous"></script>       <script>         $(document).ready(function() {    ...

Introduction:                     Firstly we have to understand why this error occurs? If we understand the problem then it  is very easy to solve the problem. While we create instances on a cloud platform, we notice lot of parameters to decrease the bill and as well as performance should remain fantastic. Actually if the instance produces no bill, it is tremendous for us. With considering these parameters, generally we create an instance with a very small amount of memory. When we configure our project, then lots of libraries/packages needed to configure the project. These libraries/packages take a bunch of memories. While there is not enough memories then the error "proc_open(): fork failed-can not allocate memory" arises.

Introduction:                        Composer is not a package manager like yum/apt, it is a tool for dependency management in php. It allows to declare the libraries that your project depends on and it will manage 'install/update' the libraries for your project. Now you are thinking that it's not dealing with packages? yes it deals with 'packages' and 'libraries' and it manages all packages and libraries per project basis, installing them into a directory  (as for vendor) inside your project. Actually it doesn't install anything globally that's why it is a dependency manager. Tech Details:                       aws ec2, amazon machine image ubuntu 18.04, Nginx(1.14), php(7.3).
