If anaconda navigator fails to start, especially if reinstallation doesn't solve the problem, it's probably a library conflict!
1. Started by anaconda-navigator icon, no response
2. In the command window, type anaconda-navigator, the error is reported as follows
anaconda-navigator
3. The error comes from here
File "C:\Anaconda3\lib\site-packages\anaconda_cloud_auth\", line 11, in <module>
from semver import VersionInfo
ImportError: cannot import name 'VersionInfo' from 'semver' (C:\Anaconda3\lib\site-packages\semver\__init__.py)
Import error from semver import VersionInfo, because semver does not have VersionInfo causing the error. The problem must be coming from semver.
conda list semver
The two were renamed and the pip install was prioritized, so the poetry-semver file was used and the conda install of semver was not used.
4. Solution, delete the library that caused the conflict
pip uninstall poetry-semver
