Cannot Open Anaconda Suddenly
Solution 1:
This error means that you installed pyqt5 with pip along side the pyqt conda package. It could be solved by you uninstalling the pip package. Try:
pip uninstall PyQt5
Then update conda:
conda update conda
and
conda update anaconda-navigator
It will surely resolve your problem.
Solution 2:
I tried all the solutions listed here but they didn't work for me. Later I was able to resolve the issue. Even though your solutions didn't directly solve my issue, the steps I used to solve it were based on the answers I found here. I will now list the steps I used to solve my issue:
python -V
# I checked the python version to make sure it's python 3.4 and aboveconda update conda
conda update anaconda-navigator
pip install PySide2
pip uninstall pyqt
pip uninstall PyQt5
Now when doing step 5&6 both pyqt and PyQt5 were not installed on the system, which was the cause of the issue
pip install qtpy
# This module was already installed on the systempip install PyQt5
# This was the final step that solved the issue
Solution 3:
I tried all the answers provided. Some steps worked some didn't. So I will just tell all the steps which finally after many trials and fails worked for me:
- cd C:\Users\UserName\Anaconda\Scripts
- pip install PySide2
- pip uninstall PyQt5
- pip uninstall pyqt (on this I got this error- WARNING: Skipping pyqt as it is not installed. So not sure if this is helpful)
- conda update conda
- conda update
- anaconda-navigator
Solution 4:
I had exactly this problem. Same error message and all.
To fix I first updated Conda:
$ conda update conda
Then updated the navigator
$ conda update anaconda-navigator
This performed an integrity check (though it took a while - you have to be patient) and found that the environment was inconsistent. It created a package plan to download and install new packages and updates as well as downgrade some packages. It asked me to approve the change before performing the change and updating the specs. Having approved it, all was performed flawlessly and I was able to relaunch Anaconda navigator without a problem.
Solution 5:
I just had a similar problem with Navigator. I typed anaconda-navigator on the command line and it opened fine. This doesn't explain why it won't open from the icon but does offer a work-around.
