Eppy（EnergyPlus脚本语言）导入报错及文件缺失问题求助

Hey there, let's work through these two issues you're facing with Eppy for EnergyPlus:

1. Resolving the AttributeError: module 'collections' has no attribute 'MutableSequence' #

This error is your immediate blocker, and it boils down to Python version compatibility. Starting with Python 3.10, the MutableSequence class was moved from the top-level collections module to collections.abc. The version of Eppy you installed via pip is likely an older release that hasn't been updated to account for this change.

Here are two ways to fix it:

• Upgrade Eppy to the latest compatible version (recommended):
  Run this command in your terminal to get the newest version of Eppy that supports Python 3.10+:

  pip install --upgrade eppy
  

  This should automatically resolve the collections import issue, as newer Eppy releases have patched this compatibility gap.

• Manually patch the affected file (if upgrading doesn't work):
  Navigate to the idf_msequence.py file in your Eppy installation directory (the path from your error log is C:\Users\...\AppData\Local\Programs\Python\Python310\lib\site-packages\eppy\idf_msequence.py):

  1. Open the file in a text editor.
  2. At the top of the file, replace any existing collections import line with:

     from collections.abc import MutableSequence
     

  3. Update the class definition from:

     class Idf_MSequence(collections.MutableSequence):
     

     to:

     class Idf_MSequence(MutableSequence):
     

  Save the file and try importing Eppy again.

2. Fixing the Missing resources Folder #

The missing resources folder is likely a side effect of a partial or corrupted installation. Here's how to address it:

• First, verify after upgrading Eppy:
  When you upgrade Eppy via pip, the installation should include all required files—including the resources folder. Check your Eppy directory again after running the upgrade command.

• Manually add the folder if still missing:
  If the folder is still gone, you can grab it directly from the Eppy source repository. Copy the resources folder contents and paste them into your local Eppy installation directory (same path as above, under the main eppy/ folder).

Once you've addressed both issues, try running from eppy import modeleditor again—it should work without errors.
