Hello i'm trying to install the composer but i have this error.
An error occurred when executing the "'cache:clear --no-warmup'" command:
In DocParser.php line 995:
  Notice: Trying to access array offset on value of type null
Any suggestion ?

Hello there!
You should change the content of this line to:
while ($this->lexer->lookahead!==null && $this->lexer->lookahead['position'] === ($this->lexer->token['position'] + strlen($this->lexer->token['value']))

The full explanation to do that may be found on doctrine/annotations#273

Hello,

It can be related to your PHP version. For now Cocorico has been tested and works with php 7.1 and 7.2.
