Windows环境下运行pyiron遇.pyiron配置错误问题求助

It looks like pyiron’s configuration is restricting where you can create projects, and the default project folder it expects doesn’t exist yet. Here’s how to resolve this:

Root Cause #

Pyiron uses a .pyiron configuration file to define allowed directories for projects. The error tells you two key things:

• The default project path C:/Users/nau/pyiron/projects/ doesn’t exist
• Your desired path C:/Users/nau/pyiron/test/ isn’t listed in the allowed project_paths

Solution 1: Stick with the Default Project Structure #

This is the simplest fix if you don’t mind using pyiron’s default setup:

1. Create the missing default folder:
   Open File Explorer, go to C:/Users/nau/pyiron/, and make a new folder named projects.
2. Create your project in the allowed directory:
   Either:
   • Navigate to the projects folder in your notebook first:

     import os
     os.chdir("C:/Users/nau/pyiron/projects/")
     pr = Project('test')
     

   • Or specify the full path when creating the project:

     pr = Project('C:/Users/nau/pyiron/projects/test')
     

Solution 2: Allow Custom Project Paths #

If you want to create projects in other locations (like your test folder), customize the config file:

1. Create the .pyiron config file:
   Open Notepad, paste the following content (adjust paths if needed):

   resource_paths:
     - C:/Users/nau/pyiron/resources
   project_paths:
     - C:/Users/nau/pyiron/projects
     - C:/Users/nau/pyiron/test
   

   Important: Use spaces for indentation (not tabs) — YAML is strict about this.
2. Save the file correctly:
   • In Notepad, go to File > Save As
   • Set "Save as type" to "All Files"
   • Name the file .pyiron (include the leading dot)
   • Save it to C:/Users/nau/ (your user directory)
3. Restart your notebook kernel and try creating the project again:

   from pyiron import Project
   pr = Project('test')
   

   This should work now since your test path is in the allowed list.

Bonus Tip #

You might also want to create the resources folder at C:/Users/nau/pyiron/resources/ to avoid future warnings — this is where pyiron stores things like potential energy parameters.
