I have a fresh global & local install of Composer on OSX 10.10. They both output the same error, and install fails.

I also tried git cloning laravel and then running composer install but I get the same errors.

Answer 1

"Psy/psysh" needs "nikic/php-parser" and this one needs "ext-tokenizer". Add/enable "ext-tonkenizer" extension from PHP and everything will work.

Answer 2

Install ext-tonkenizer steps:

cd /var/package/php-7.0.12/ext/tokenizer

/usr/local/php7/bin/phpize

./configure --with-php-config=/usr/local/php7/bin/php-config

make

make install

/usr/local/php7/bin/php -m | grep tokenizer

tokenizer
