Trying to install a legacy extension in 5.3.x, gives the

[RuntimeException]
  The lock file does not contain require-dev information, run install with the --no-dev option or run update to install those packages.

Steps to Reproduce

– Untar 5.3.0
– Make an installation running ezsetup
– Try to install ezfind (for instance) ( php composer.phar require --prefer-dist ezsystems/ezfind-ls:5.3.* ) as referred in documentation

The above error appears.
To avoid it, I removed composer.lock and re-tried the above command and the error no longer appeared.

Even if I do an upgrade to 5.3.5, the exception still occurs.
