Composer not working on Windows (WSL)

Question

Installing Composer and trying to run it does not seem to work on a php-fpm container when this container is running on Windows (Ubuntu bash / WSL).

However, it runs smoothly everywhere else.

username@docker-php:/var/www/project$ php composer.phar update                                                      


  [ErrorException]

  ): failed to open stream: phar error: Cannot open phar archive "/var/www/project/composer.phar" for reading     

Also, running the command again results into a different error:

username@docker-php:/var/www/project$ php composer.phar update

Any idea how to make this work?

Fixed installing Composer in a different way!

RUN curl -sS https://getcomposer.org/installer | php \
            && mv composer.phar /usr/local/bin/ \
            && ln -s /usr/local/bin/composer.phar /usr/local/bin/composer
