ModuleNotFoundError: No module named 'gnsspy.io'

[Pineappple345]

Hello! I am new and this is the first module that I tried to install. I got a problem when I want to import the module. First I will tell you how I installed it:

1. I saved the zip file in "...miniconda3\envs\informatik2\Lib\site-packages"

2. After extracting the zip "gnsspy-master" I had to call it "gnsspyMaster" because Python doesn't like it if a module name has a "-"

3. Changed in setup.py the 17th line to "return [str(ir.requirement) for ir in reqs]"

4. Opened "Anaconda Powershell Prompt" changed the address to "...miniconda3\envs\informatik2\Lib\site-packages/gnsspyMaster"

5. entered "python setup.py install"

6. Opened Python 3.7 entered "import gnsspyMaster" and "help(gnsspyMaster)"

7. " Help on package gnsspyMaster:

                     NAME
                         gnsspyMaster
   
                     PACKAGE CONTENTS
                         gnsspy (package)
                         setup
   
                     FILE
                         (built-in)

8. Entered in Python "import gnsspyMaster.gnsspy"

9. Then I got this Error: Traceback (most recent call last):

             File "C:\Users\annae\Desktop\SatPos\untitled0.py", line 9, in <module>
               import gnsspyMaster.gnsspy
   
             File "C:\Users\annae\miniconda3\envs\informatik2\lib\site-packages\gnsspyMaster\gnsspy\__init__.py", line 23, in <module>
               from gnsspy.io.readFile import (read_navFile, read_obsFile, read_sp3File,
   
           ModuleNotFoundError: No module named 'gnsspy.io'

Why do I get this Error and how can I fix it? I am using Python 3.7
