Running pyiron under Windows leads to error about .pyiron configuration - pyiron

Question

I installed pyiron according to the instructions under Windows via conda. Everything worked without any errors. Then, I started a new notebook, and ran the commands:
from pyiron import Project
where I got the message:
Fall back to default configuration: {'resource_paths': ['~/pyiron/resources'], 'project_paths': ['~/pyiron/projects']}
and then, I tried to start a new project via:
pr = Project('test')
Here, errors occurred such as:
ValueError Traceback (most recent call last)
<ipython-input-2-f4cd01081291> in <module>
----> 1 pr = Project('test')
C:\Anaconda3\lib\site-packages\pyiron\project.py in __init__(self, path, user, sql_query)
108
109 def __init__(self, path="", user=None, sql_query=None):
--> 110 super(Project, self).__init__(path=path, user=user, sql_query=sql_query)
111 self.job_type = JobTypeChoice()
112 self.object_type = ObjectTypeChoice()
and finally, the message:
ValueError: the current path C:/Users/nau/pyiron/test/ is not included in the .pyiron configuration. ['C:/Users/nau/pyiron/projects/']
(nau is my user name). Do I have to initialize a file .pyiron in a certain folder first? If yes, how? The folder C:/Users/nau/pyiron/projects/ didn't exist.

This is a bug and should be fixed in the code - I am going to create a separate issue on Github shortly.
In the mean time you can fix it on your system, by either creating the folder manually:
C:/Users/nau/pyiron/projects/
And then execute the jupyter notebook in this folder.
Or you can create the pyiron configuration files by executing the following commands:
import pyiron
pyiron.install()
This is going to ask you:
It appears that pyiron is not yet configured, do you want to create a default start configuration (recommended: yes). [yes/no]:
And then you can confirm with yes which is going to create a C:/Users/nau/.pyiron file with the configuration. This file you can then update manually. By changing the line:
PROJECT_PATHS = C:/Users/nau/pyiron/projects/
to:
PROJECT_PATHS = C:/Users/nau/pyiron/
I hope this solves your issue.
Ps: Can you tell me which version of pyiron you are using? You can identify the version using conda list pyiron.
