pecl/pear requires mbstring

[billiam13s]

I installed mbstring in docker docker-php-ext-install mbstring and then trying to install mailparse pecl install mailparse-2.1.6. pecl result in pecl/mailparse requires PHP extension "mbstring". After grep mbstring from php -i, it does display mbstring result. Anyone know how to enable pecl or pear to load mbstring?

Thanks

if you've got a custom dockerfile you could add RUN docker-php-ext-install mbstring, quick and dirty way is to do an docker exec -it name_of_your_container docker-php-ext-install mbstring. The later is useful to get you out of a tightspot, but won't persist.

mbstring is installed, but pear or pecl think mbstring is missing when installing mailparse.

[booyaa]

when do you call pecl? can you share your dockerfile or docker commands?

[billiam13s]

FROM php:5.6

RUN docker-php-ext-install mbstring

RUN pecl install mailparse-2.1.6

will result

Step 3 : RUN pecl install mailparse-2.1.6
 ---> Running in ff88e4f6e582
pecl/mailparse requires PHP extension "mbstring"
No valid packages found
install failed

I tried on PHP7, 5.6, 5.5. All of those versions of pecl does NOT have mbstring extension enable, while grep from php -i php -i | grep mbstring do exists.

Ouch, I found a clue in http://www.cerberusweb.com/forums/thread-25.html:

use

pear install pecl/mailparse

The difference between the "pear" and "pecl" commands is that "pecl" disables php.ini so that you can overwrite extension .so or .dll files that would otherwise be in use and locked for write. So, unless mbstring is built into PHP (not a loaded module in php.ini), you won't be able to install mailparse.

Now, I can't get that first command to work, but it does seem plausible that mbstring has to be built into PHP for this to work, so this might be a decent justification for doing so.

(which would also relate to / close #34)

[billiam13s]

I read about issue #34. It would be nice to have mbstring enable by default.

I tried pear install pecl/mailparse-2.1.6 and pecl install mailparse-2.1.6. pear will run for try to install then will fail due to mbstring is missing. pecl will fail right away. I hope #34 will solve this problem, meanwhile are there any workaround solution can be use?

This is just the beginning of my setup, without mailparse I can't run composer install.

Thanks,

Hi i've same problem as describe here : https://bugs.php.net/bug.php?id=71181

[bizmate]

mbstring is also not enabled on php:5-fpm for some reason and since this can only be enabled at install time there is not way to add it unless you build your own container from scratch.

[tianon]

It can be enabled generally post-install, but pecl explicitly ignores the configuration which allows for that. I'll make a PR shortly to include support for it by default.

Containeur are already rebuild in dockerhub repository ? Because the probleme are still present :

docker pull php:5.6-cli

docker run --rm -it php:5.6-cli bash

pecl install mailparse-2.1.6
pecl/mailparse requires PHP extension "mbstring"
No valid packages found
install failed

I guess they haven't have time to publish the tags at dockerhub yet. Last push was 13 days ago. https://hub.docker.com/r/library/php/tags/
