"It appears the composer tool is not yet installed"

Hi guys,

I just updated Piwik to I think it was Piwik 2.0.1. However, after the update I get (instead of a proper inlog page) a few warnings and this message:

It appears the composer tool is not yet installed. You can install Composer in a few easy steps:
In the piwik directory, run in the command line the following (eg. via ssh):

curl -sS https://getcomposer.org/installer | php

php composer.phar install

I just have a kind of small technical knowledge, is it possible to fix without losing the data I already collected? Hope you can help me, I will give you many thanks in advance :slight_smile:

I am sorry, I planned to post it in the general questions section but something went wrong…

if you deploy Piwik from GIT then you need to install composer tool with this command:

curl -sS https://getcomposer.org/installer | php

Yes, I understand, but I don’t know how to deploy piwik from GIT.

Sounds like some files are not uploaded correctly. Try reupload all files of piwik 2.0.1 and it should work?
