Windows 7, 64 bit
Anaconda 2018.12 (Upon installation Anaconda is added to PATH)
Jupyter Notebook 5.7.4
Python 3.7.1
IPython 7.2.0
And please note that pysqlite2 has been installed and is available under:
Short story:
Running Jupyter notebook from command prompt raises error pysqlite2 not found.
This does not happen when Jupyter is launched from Anaconda Navigator or Anaconda prompt.
Installing nbExtensions raises error pysqlite2 not found.
Anaconda is addad to path upon installation.
pysqlite2 is installed using conda install -c anaconda sqlite as described on github
There are some posts on StackOverflow that discuss similar problems, but none that describe a possible solution:
I'm experiencing several problems with the latest Anaconda and Jupyter versions on Windows 7. Earlier, I could easily navigate to a folder using a command prompt and fire up Jupyter and get a list of available .ipynb files using the command jupyter notebook.
Now, the following command will raise the error below:
Snippet 1:
C:\notebooks>jupyter notebook
Output 1 => Error:

Copying and pasting that link to a web browser launches a Jupyter Notebbok and all seems to be OK, apart from the fact that I'm no longer able to launch Jupyter using a simple command batch that I used to earlier.
Problem 1 is something I could live with, but the same issue causes other problems as well.
Problem 2:
I've been using Jupyer Notebook Extensions for some time, and really like the enhanced toolbox this provides. But reinstalling these tools now raises an error related to pysqlite2.
