无法安装php solr扩展

Question

Using pecl install -n solr gives No releases available for package "pecl.php.net/solr" install failed

Also tried pear install pecl/solr which gives the same output : No releases available for package "pecl.php.net/solr" install failed

I'm using a Mac and php56.

Output of pecl -V PEAR Version: 1.9.4 PHP Version: 5.6.25 Zend Engine Version: 2.6.0 Darwin Kernel Version 15.4.0: Fri Feb 26 22:08:05 PST 2016; root:xnu-3248.40.184~3/RELEASE_X86_64 x86_64 PEAR Version: 1.9.4 PHP Version: 5.6.25 Zend Engine Version: 2.6.0 Darwin Kernel Version 15.4.0: Fri Feb 26 22:08:05 PST 2016; root:xnu-3248.40.184~3/RELEASE_X86_64 x86_64

Another important piece of information is that, pear and pecl were not available in my system, so I installed them using

sudo php /usr/lib/php/install-pear-nozlib.phar -d /usr/local/lib/php -b /usr/local/bin

Update

Tried sudo pecl install -n solr and now it seems to go one step further

Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script. ERROR: phpize failed

Answer 1

Luckily stumbled upon

PEAR package install fails

which led to execute pear list-upgrades which showed some kind of permission issue with cache directory, manually created the directory using sudo at the specified location ( /private/tmp/pear/cache )

And then used sudo to install the solr extension as sudo pecl install -n solr which threw the following error :

Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script.

brew install autoconf followed by sudo pecl install solr worked.
