First time user here so please be gentle!
I installed Grav (with Admin) from the zip and it appears to work perfectly.
Until I try to install a theme. Then I get the above error. The problem is that according to phpinfo the feature described in the help documents is installed and enabled already.
So why the error and how do I fix it?
This is what phpinfo shows for zip
| Zip | enabled |
|---|---|
| Zip version | 1.15.6 |
| Libzip headers version | 1.6.1 |
| Libzip library version | 1.6.1 |
Any assistance gratefully received.
Follow up …
Further study of the docs showed me how to install via the Admin interface - and that works.
Weird … so my immediate problem is solved but why the error in the first place? Only thing I can think of is that the PHP being used from my command line is not the same as is used when in the browser. No idea how to check but …
if you have terminal access / command line access try
php -v
php --ini
With the information returned it will show where the current php.ini and php directory it is being run.
php --re zip (php --re ) will return the information of the version and if it is enabled.
Different “stacks” may configure a different version of php to load, when apache loads, so might be why you got differences.
Glad your sorted though 
Thanks for that - never done much with the PHP command line stuff.
Looks like it is pointing to the default install on my Mac - not the MAMP instance I am running Grav in. And as suspected zip is not enabled in that version.
One more thing to understand in this wonderful Unixy/Linuxy world!
Thanks for your help.
One question that does come out of this - is it possible to persuade phar to use a different zip? php -i shows that I have gzip (and others including bzip2) enabled in this config. Be nice to use that instead of fighting with installing an additional component.
Thank you Glad I could help… yep I am still a noob to grav… but come from a support background… but there is some great people on here… and the discord chat channel is great. Happy learning !
I can’t thank you enough for this. If you are representative of the helpfulness of this community I think I’ll be hanging around!
I have had abortive attempts to install composer in the past but could never get ti to work - never saw the post on that that you referenced and it looks as if it will do the job for me.
Thanks again.
