trouble installing drizzlepac

Question

I'm trying to install drizzlepac to follow this tutorial on aligning hst images: https://spacetelescope.github.io/notebooks/notebooks/DrizzlePac/align_to_catalogs/align_to_catalogs.html

However, I get the following errors:

   ERROR: Command errored out with exit status 1:

This was using pip within an anaconda prompt. If I try to use conda, it can't find the package.

I'm extremely new to python, so I'm sure I'm doing something relatively basic wrong! But I've been bashing my head against this for a while.

Answer 1

As I understand it, you should not be using pip with Anaconda or you will get into a mess. Unfortunately, that's not the main issue here.

The workbook you linked has a banner at the top that mentions an initialization workbook, which is on this page. On that page it states that "Users unfamiliar with Anaconda/Astroconda should see the documentation."

I am unfamiliar with Astroconda, so I went to the documentation page which lists the following requirements:

System Requirements

• 64-bit Intel/AMD processor (x86_64)
• 64-bit Linux (glibc ≥ 2.12) or Mac OS X (≥ 10.7)
• BASH or ZSH as your default shell environment (T/CSH is NOT supported)

I see from your command line that you are using this on Windows. That is not listed as a supported operating system: the software is Linux/Mac only.
