That is an interesting error! I looks like makedirs(), which should not do anything if the directory already exists, is getting confused and trying to mkdir() the current directory ..

I have just committed a possible fix. If you'll try this:

pip install https://github.com/skyfielders/python-skyfield/archive/master.zip

then you might be able to get past the error. Let me know what happens!

Thank you. I tried and now get a NameError:

from skyfield.api import Loader

Traceback (most recent call last):
File "D:\Programme\miniconda\envs\envpy3\lib\site-packages\skyfield\iokit.py",

mkdir(name, mode)
PermissionError: [WinError 5] Zugriff verweigert: '.'

During handling of the above exception, another exception occurred:

Drat, I cut-and-pasted that code from the modern Standard Library without changing "name" to the actual variable that holds the directory name in this case.

I've updated the code, please try again!

Hi @brandon-rhodes
we do use your library in our mission support system and @gisi90 tracked it down.
https://bitbucket.org/wxmetvis/mss/issues/446/mss-python-crashes-when-started-in-conda

Do you plan a minor bug fix release with this improvement?

[gisi90]

I've updated the code, please try again!

@brandon-rhodes
Great, now it works!

[brandon-rhodes]

@ReimarBauer Yes, I've just released a new version that includes the fix. Enjoy!

@ReimarBauer Yes, I've just released a new version that includes the fix. Enjoy!

Many Thanks, just pushed a new build for our application.
