Cannot install into a new installation of ezplatform: nikic/php-parser

[jdcrecur]

After setting a new installation of ezplatform up I cannot install this migration tool.

This is the composer file of the new ez install, plus the additional line for this migration tool in the require array:

This is the output when trying to install, there appears to be a conflict regarding the nikic/php-parser package:

I think this is already fixed in branch 4.0, which is out in RC state only. Could you try installing that version of ez migration bundle and see if all works?

[jdcrecur]

Ah ok brilliant, sure will test.

[jdcrecur]

Yup setting the "minimum-stability": "RC", in the composer.json and grabbing the latest code fixed it all.

A little nervous leaving this as a min stability level, but will do for dev ;)

Cheers, John

I agree about min-stability. Just make sure you add prefer-stable as well, so that you dont get beta versions of other packages. To reassure you, the current status of 4.0, as far as I am concerned is: "done, but want to add more tests before release".
