Composer curl error 60: SSL certificate problem: self signed certificate in certificate chain

Question

I'm working with Symfony 5 and I need to install 'knplabs/knp-snappy-bundle' with composer but I have this message:

[Composer\Downloader\TransportException]
  curl error 60 while downloading https://repo.packagist.org/packages.json: SSL certificate problem: self signed certificate in certificate chain

please help me

I tried to add cacert.pem into my php.ini with

curl.cainfo ="C:/wamp64/bin/php/php7.3.21/extras/ssl/cacert.pem"

I tried to disable the verify_peer in my composer.json and nothing is working.

this is my composer diag :

Answer 3

This configuration option: allow_self_signed comes from nowhere, it has no effect; It doesn't even appear in the documentation of composer.

I lost hours of precious time due to this misleading option.

If you have a similar problem I would recommend to use the latest version of PHP (that meets your requirements, obviously) and the latest composer version, etc. Works for me, but YMMV.
