Anaconda 和 Windows 10 上的 jupyter 笔记本

Question

It just does not seem to work. I get several different errors.

System: Windows 10 Anaconda: 64 bit, latest download. Anaconda 3. python: 3.9

1. For some reason ssl does not load. I have tried all the solutions proposed online, such as adding Anaconda3, Anaconda3\bin, Anaconda3\Lib to the PATH variable. Adding the Anaconda3\pkgs\openssl-1.1.1n-h2bbff1b_0\Library\bin to the PATH variable.

2. I do have the libssl-1_1-x64.dll.

The errors I get:

1. Neither Anaconda Navigator, nor the jupyter notebook starting scripts do anything. They just fail without any errors.

2. The only clue I have is when I start the python command prompt and try to "import ssl". I get the following error.

   'MySQL' is not recognized as an internal or external command, operable program or batch file. 'MySQL' is not recognized as an internal or external command, operable program or batch file.

When I try pip install pyopenssl, this is the error I get.

Thanks for all responses.

Python 3.7 anaconda environment - import _ssl DLL load fail error

This post answers the question. Looks the the idiots of anaconda look for SSL and other dlls in C:\anacnoda3\dlls. They do not use the windows path resolution. I guess they do not trust Windows to do the right thing.

Copying the ssl and crypto dlls to Anaconda3\Dlls location solved the problem.
