wagon searches system python for constrained dependencies when using embedded python #36

Closed gilzellner closed 8 years ago

gilzellner commented 8 years ago

how to reproduce: install a package with embedded python like: https://gigaspaces-repository-eu.s3.amazonaws.com/org/cloudify3/3.4.0/m5/mgmt-worker-3.4.0~m5-394.el7.x86_64.rpm create a constraints file: pip freeze > const.txt download a wagon which has a dependency that exists in the constraints and doesn't exist in the system python like: http://repository.cloudifysource.org/org/cloudify3/wagons/cloudify-diamond-plugin/1.3.2/cloudify_diamond_plugin-1.3.2-py27-none-linux_x86_64-centos-Core.wgn install with prefix and constraint: wagon install -s cloudify_diamond_plugin-1.3.2-py27-none-linux_x86_64-centos-Core.wgn -a '--prefix /opt/mgmtworker/env/plugins/cloudify-diamond-plugin-1.3.2 --constraint /opt/mgmtworker/env/const.txt --verbose'

one of the errors show usage of wrong pip:
