When I try to run the command phpunit from the command line, I received the following error:
Class 'DOMDocument' not found
This was not happening before. I remember having to remove and reinstall PHP.
What can cause this error, since DomDocument is a native PHP class?
Note: I am using the Ubuntu operating system.
To install in Ubuntu I believe this is the command, if it is php5.6:
sudo apt-get install php5.6-xml
Other linux based on Debian or older versions of Ubuntu I believe works like this:
sudo apt-get install php5-dom
If it's 7.0 would be this:
sudo apt-get install php7.0-xml
php7.1:
sudo apt-get install php7.1-xml
The only thing that can change is if you are using PPA, then it will depend on how you installed
Some Linux distributions separate the DOM extension into another package to make the installation cleaner and more organized.
I do not remember the package name in Ubuntu, but it's something like php-xml. After installing, make sure the extension is active in php.
You can check by looking at phpinfo ();
If it is not active, simply add the extension in your php.ini:
extension=dom.so
