I was trying to install Pear in Kali Linux 2018.3. I downloaded go-pear.phar and ran the command php go-pear.phar. But I am getting a lot of PHP Startup: Unable to load dynamic library errors and it also seems that an older version of pear is also installed. Here are the warnings I'm getting:

Below is a suggested file layout for your new PEAR installation.  To

Run it without parameters to see the available actions, try 'pear list'
to see what packages are installed, or 'pear help' for help.

Thanks for using go-pear!

How do I fix these Warnings?

  • Isn't Pear in the default repositories, or at least a compatible PPA (if Kali has those)? Is there no Pear install guide that suggests how to proceed? – Xen2050 Nov 20 '18 at 7:38
  • It should have been in the default repository. But pear command was not running earlier. So I installed Pear using .phar file. But now I get this Warning. – Gautam Vashisht Nov 20 '18 at 8:12
  • If the default version was broken, then maybe whatever broke it is still breaking this other version – Xen2050 Nov 20 '18 at 8:14
  • I have solved the PHP Startup Warnings by commenting the extension= lines in php.ini file. But I still don't know the solution of older version of Pear Warning. – Gautam Vashisht Nov 20 '18 at 8:16
