Installing Blackfire prob issue

Question

Having some issue trying to get Blackfire.io set up on my homestead box.

Followed the installation guide a couple of times now, and no having no errors.

When I try to use the chrome companion I get the follow error ...

Are you authorized to profile this page? Probe not found, invalid signature

Also when I try to check out what version of the prob I am using via php --ri blackfire I get the follow message despite installing it as per the guide

Extension 'blackfire' not present.

Any ideas!?

Many thanks!

FWIW, I'm very new to Blackfire on Linux. My impression is that if `php --ri blackfire` returns an error, it's either not installed or it's not in your path. Also try `php -i | grep blackfire`. If that shows nothing, it seems like Blackfire isn't installed. — Steve Johnson, Apr 15 '16 at 16:52
Hi, Sorry I never got it working and time ran out so I had to unfortunately continue without solving. — Dean Collins, Aug 31 '16 at 08:28

in file

/etc/php5/mods-available/blackfire.ini

add

extension=blackfire.so

In my case, I had to check the black-fire agent status, and when I found out it was not active I restart it and it works fine.

To check the status:

sudo /etc/init.d/blackfire-agent status

To restart :

sudo /etc/init.d/blackfire-agent restart

I had the same problem when installing blackfire probe as mentionned in the official documentation. And here is how i solved it.

Since I am using MAMP's php in my terminal i installed the PHP Probe manually instead of installing it with homebrew.

In fact in the first place i tried to instal it with homebrew and that's how i get the same error as you :

When i run this command :

php --ri blackfire

I get :

Extension 'blackfire' not present.

To fix this issue i had to install the probe manually by following theses steps:

download the probe library as mentionoed in the blackfire doc

You should have a file like this : blackfire-php-**********.so

rename it to: blackfire.so
execute this command in your terminal, it should tell you where you can put the downloaded file:

php -i | grep 'extension_dir'

move the blackfire.so file to the mentionned directory.
Close all your terminal windows and restart mamp
Execute php -m in your terminal; if you can see blackfire in the list that means that your extension is working correctly.
