PHP Enable bz2 Extension In Php.ini

Question

I an trying to download a file using composer in php, but the file needs to be decompress with bzipped. Here is the error I get:

[UnexpectedValueException]                                                   
unable to decompress bzipped phar archive "/home/admin/public_html/subdo  
mains/testing4/vendor/jakoch/phantomjs/da2db411008833dfaa24e92e129aa037.bz2  
" to temporary file, enable bz2 extension in php.ini   

In my php.ini file I have added:

extension = "bz2.so" 

After adding that I still get the error when I try and install the file.

When I run infophp(-1) I get:

bzip2 compression   disabled (install pecl/bz2)

Do I need to enable bzip2? If so how do I do it. Am I doing something wrong with allowing the extension?

Thanks! Solved my problem installing github.com/jakoch/phantomjs-installer in Homestead. It was requiring bz2. – Commines

You can use sudo apt-get install php-bz2 for php 7.0 and 7.1 – Retiarius

This solved my problem as well while installing phantomjs on php 7.2 thanks! – Medicinal

Answer 2

Enabling an extention in PHP is not only by including it into php.ini file, you need to recompile your PHP installation with package support being enabled, in order to do this for bz2, you have to execute the needed pecl command:

pecl install bz2

To install pecl you have to install pear and phpize, on a debian based system, the following command should be sufficint:

apt-get install php5-dev php-pear

Finally you need to add the new extension to php.ini file, Don't forget to reload your web server after that.
