Thank you for the defect report

• I am using the latest version of RAVEN.
• I have read the Wiki.
• I have created a minimum, reproducible example
  that demonstrates the defect.

Defect Description

If python is install such that pip3 is a different version of python than in the raven libraries environment, the build raven will fail.

This will fail when the tests are run because the built version will be a different version from the version that is imported.

Steps to Reproduce

Create two installs of python, and use one for the python command and the other for the pip3 command.

Expected Behavior

Raven can build python.

• Is it tagged with a priority: critical, normal or minor?
• If it will impact requirements or requirements tests, is it tagged with requirements?
• If it is a defect, can it cause wrong results for users? If so an email needs to be sent to the users.
• Is a rationale provided? (Such as explaining why the improvement is needed or why current code is wrong.)

For Change Control Board: Issue Closure

• If the issue is a defect, is the defect fixed?
• If the issue is a defect, is the defect tested for in the regression test system? (If not explain why not.)
• If the issue can impact users, has an email to the users group been written (the email should specify if the defect impacts stable or master)?
• If the issue is a defect, does it impact the latest release branch? If yes, is there any issue tagged with release (create if needed)?
• If the issue is being closed without a pull request, has an explanation of why it is being closed been provided?
