anaconda navigator无法打开Cannot run solver. No functioning SAT implementations available.
不知道是哪天python环境从python3.6自动升级到了3.7，然后出现一系列问题。但是重新安装python3.7对应的适应包之后，大多能够解决。到目前仅剩的问题是，anaconda navigator无法打开，然后开机需要手动activate base启动conda环境.(base是我的conda环境名。)到现在没有发现于我处一样问题的人。已经将这个问题反馈了，但是好像维护者已经关闭这个issue了。
有需要的朋友们可以参考点这里
在网上看到很多答案Windows里Anaconda-Navigator无法打开的解决方案（详细
conda update anaconda-navigator无法使用。
I have tried for any solution I can find on the internet, but unfortunately, it can’t work out. The original question is that I found that the brand of anaconda can’t open.I have no idea about that. What’s more, now I try to upgrate a module in pycharm use anaconda, some mistake happens. CondaHTTPError: HTTP 000 CONNECTION FAILED for url
and then I type the anaconda-navigator in the terminal, the result are asfollow:
C:\Users\Administrator>anaconda-navigator
Traceback (most recent call last):
File "D:\Anaconda3\lib\site-packages\qtpy\__init__.py", line 148, in
from PySide import __version__ as PYSIDE_VERSION # analysis:ignore
ModuleNotFoundError: No module named 'PySide'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "D:\Anaconda3\Scripts\anaconda-navigator-script.py", line 10, in
sys.exit(main())
File "D:\Anaconda3\lib\site-packages\anaconda_navigator\app\main.py", line 125, in main
from anaconda_navigator.utils.logs import clean_logs
File "D:\Anaconda3\lib\site-packages\anaconda_navigator\utils\__init__.py", line 15, in
from qtpy.QtGui import QIcon
File "D:\Anaconda3\lib\site-packages\qtpy\__init__.py", line 154, in
raise PythonQtError('No Qt bindings could be found')
As you say, my conda environment is this:
C:\Users\Administrator>conda info -e
# conda environments:
#
base * D:\Anaconda3
The next, I tried the above solution ,results looks like :
(base) C:\Users\Administrator>Conda D:\Anaconda3\Scripts\conda.exe install -p D:/Anaconda3 scipy -y
usage: conda-script.py [-h] [-V] command ...
conda-script.py: error: argument command: invalid choice: 'D:\\Anaconda3\\Scripts\\conda.exe' (choose from 'clean', 'config', 'create', 'help', 'info', 'init', 'install', 'list', 'package', 'remove', 'uninstall', 'run', 'search', 'update', 'upgrade')
(base) C:\Users\Administrator>conda update anaconda-navigator

One solution make me do such a thing:
(base) C:\Users\Administrator>conda upgrade --all

Update conda and try again.
$ conda install -p "D:\Miniconda3" "conda>=4.6"
and then :

Ican’t figure this out ,so I submit this question to you for help.
There exists some thing I can’t tell you, when I type python in the terminal ,I got my python version is 3.7.2 and in my machine only exist one conda environment. But in pycharm, the project Interpreter called Python3.6 D:\Anaconda\python.exe.This bother me for a long time . Thanks for you help.
