Installation error in windows gcc exit status 1 with no sys/mman.h file about exoplanet

[dfm]

This is actually falling while trying to install rebound before it even gets to exoplanet. So you could look there to see if you can find tips. Let's leave this issue open though because rebound is not a required dependency for all of exoplanet so we should make it possible to skip installation. It might work for you to try pip install --no-deps exoplanet for now but that might lead to more problems down the line.

Thank you Dan very much for your reply (and for this library).

I tried your suggestion. The command gave me:

(exoplanet_env) C:\Users\Vital>pip install --no-deps exoplanet
Requirement already satisfied: exoplanet in d:\programs\anaconda3\envs\exoplanet_env\lib\site-packages\exoplanet-0.2.4.dev6+g2171caa-py3.7.egg (0.2.4.dev6+g2171caa)

However, when I tried to import exoplanet:

In [1]: import exoplanet

However, if it is a rebound library issue I shall investigate its requirements...

[Vital-Fernandez]

It seems rebound is actually not compatible with windows. From the documentation:

Note: If you want to run REBOUND on Windows, the best way is likely to install the Windows Subsystem for Linux. After installing the gcc compiler, e.g., sudo apt-get install gcc, you should be able to install REBOUND and any python libraries by following the Linux/Mac installation instructions in this documentation. Unfortunately we do not have Windows installations ourselves, so we cannot actively support installation problems. Thanks to Keto /Zhang for finding this workaround.

... so I better change OS :)

@Vital-Fernandez: I just published a new release that moves rebound to an optional dependency so:

python -m pip uninstall rebound_pymc3
python -m pip install -U exoplanet

should now do the trick for you. It should also be available for windows on conda-forge soon.

Thank you very much! I am going to test it right now!

[Vital-Fernandez]

@dfm So far all the tests I have run work fine 👍

Thanks a lot for your work.

Hi, Just checking regarding this.
Despite rebound being pushed to the optional dependencies.. it will still be required to run the unit tests, right?

Just trying to diagnose the errors there and hence am wondering if this is the main cause.

[dfm]

Ah - good point! I believe that that is true. Let's open a new issue to move those to optional as well.
