Anaconda Installation points to network drive as home folder - cannot start Spyder and Anaconda Navigator

问题

After installing Anaconda 4.3.1, Spyder and Anaconda Navigator do not run. When trying anaconda-navigator through the Anaconda Prompt, I get as an end error:

binstar_client.errors.BinstarError: O:: The system cannot find the path specified

conda config --show:

So the problem seems to be that under envs_dirs I have an O:\ .conda\envs entry, and it seems to be set as the home directory for Anaconda. O: is a network drive on this machine, and I have no write permission on it. I want to remove this entry from envs_dirs, but somehow can't.

What I have tried so far and it has not worked:

reinstalling Anaconda with the network drive disconnected still results in O:\ being the home drive
reinstalling Anaconda without automatic PATH through the installer and adding it later
reinstalling Anaconda with Run as Administrator
conda config remove-key envs_dirs :

CondaKeyError: Error with key 'envs_dirs': key 'envs_dirs' is not in the config file
set CONDA_ENVS_PATH=C:\Anaconda3\envs;C:\Users\Geo01\AppData\Local\conda\conda\envs
put a .condarc file of my creation under C:\Anaconda3 with the following contents:

envs_dirs:

-C:\Anaconda3\envs

-C:\Users\Geo01\AppData\Local\conda\conda\envs

A similar question has been asked before, with no answer, yet.

回答1:

Problem was occuring because the HOME and HOMEDRIVE python environmental variables were set to O:.

This could be checked by os.environ['HOME'] in another python interpreter on the computer (in this case, from QGIS).

I fixed it by putting

import os
os.environ['HOME']='C:\\'
os.environ['HOMEDRIVE']='C:'

at the beginning of the spyder-script.py and anaconda-navigator-script.py under C:\Anaconda3\Scripts
