sudo: pecl7.2-sp: command not found
I am on ubuntu 16:04 and the following got it working for me (more or less):
Run the following command:
sudo apt-get install php-pear php-dev
Now you can run the command pecl instead pecl7.2-sp - seems to work fine though:
sudo pecl install geoip-beta
Hope that helps.
I had to install imagick for php7.3 so I was getting same error using command like this
sudo pecl7.2-sp install imagick
What worked for me is running the command like this
pecl -d php_suffix=7.3 install -f imagick
