python dependency error [Jinja2 -> Markupsafe] while installing a custom package [MYPACKAGE]

I am trying to install a package which has Jinja2==2.10 as dependency package. And Jinja in turn has a dependency on Markupsafe but when it is installing markupsafe it is giving a conflicting error. Why is the version installed of Markupsafe is "0.0.0" ?

I tried the following to no avail:

1. manually installing markupsafe version 1.1

2. manually install Jinja2==2.10

      Downloading/unpacking MarkupSafe>=0.23 (from Jinja2==2.10->MYPACKAGE)
      Downloading MarkupSafe-2.0.0a1.tar.gz
      Running setup.py egg_info for package MarkupSafe
