I have a problem I thought would be solved with Ubuntu 12.10, but no luck... I had the same thing with 12.04 when trying to install something with PEAR :
Warning: file_exists(): Unable to find the wrapper "channel" - did you forget to enable it when you configured PHP? in Package.php on line 1518
PHP Warning: file_exists(): Unable to find the wrapper "channel" - did you forget to enable it when you configured PHP? in /usr/share/php/PEAR/Downloader/Package.php on line 1518
PHP Stack trace:
PHP 1. {main}() /usr/share/php/pearcmd.php:0
PHP 2. PEAR_Command_Common->run() /usr/share/php/pearcmd.php:305
PHP 3. PEAR_Command_Install->doInstall() /usr/share/php/PEAR/Command/Common.php:271
PHP 4. PEAR_Downloader->download() /usr/share/php/PEAR/Command/Install.php:661
PHP 5. PEAR_Downloader_Package->initialize() /usr/share/php/PEAR/Downloader.php:279
PHP 6. PEAR_Downloader_Package->_fromFile() /usr/share/php/PEAR/Downloader/Package.php:160
PHP 7. file_exists() /usr/share/php/PEAR/Downloader/Package.php:1518
For this example, I tried to install PHPUnit, but it is the same message with any package.
I googled a lot on this and tried many solutions :
- uninstall it with apt-get remove
- purge it with apt-get purge
- delete the remaining files manually
- installing then upgrading it
Does anybody have any idea on how to fix this ?
Thanx !
EDIT :
Always the same, it's when you post your question that the answer pops up !
Here is the link to the trick that did it : https://stackoverflow.com/a/6596669/2061163
This problem occured because I had two versions of PEAR installed on my system, don't know why...
