How to install gettext extension for php on Heroku?

Firstly you need to use the ext- prefix to apply extensions.

{   "require": {      "ext-gettext": "*"    },    "require-dev": {      "heroku/heroku-buildpack-php": "*"   }}

Run composer update

If you still get error it means composer cannot update your vendor files for gettext. I had same issue and think it's a composer problem.

For true parity you should try and obtain the the lib required but you could just ignore the lack of a local gettext with:

composer update --ignore-platform-reqs

Composer will then run without error and you can then push that up to Heroku.Heroku will then build PHP with gettext enabled.
