无法在Anaconda中安装PuLP

Question

I have been getting error-messages when trying to install PuLP within my Anaconda environment:

Preparing transaction: done Verifying transaction: done Executing transaction: failed ERROR conda.core.link:_execute(507): An error occurred while installing package 'conda-forge/label/cf201901::automat-0.7.0-py_1'. CondaError: Cannot link a source that does not exist. C:\\Users\\MarkKremer\\Anaconda3\\Scripts\\conda.exe Running conda clean --packages may resolve your problem. Attempting to roll back.

I have tried all kind of this to resolve this issue, but nothing seems to work. The strange thing is that I have had PuLP working on this computer before, but somehow I managed to break it and can't get it fixed.

What I've tried:

1. Different commands to install such as conda install -c conda-forge pulp and conda install -c conda-forge/label/cf201901 pulp )
2. Using conda clean --all , conda clean --packages etc.
3. Fully delete and reinstall Anaconda.
4. Format the harddisk and create a clean install of Windows 10.

None of these things seem to work. Does anyone recognize this problem or have any suggestions for possible solutions?

I'm using Python 3.7 on Windows 10, with a 32bit Anaconda installation

I finally managed to resolve the issue myself. In case anyone else is experiencing this issue, I'll share my solution:

My solution:

• Reinstall the automat package by running conda uninstall automat followed by conda install automat .
• Open Anaconda Promst as administrator
• Run conda install -c conda-forge/label/cf201901 pulp
