[PYTHON] Error "Entry point not found" when starting Jupyter Notebook in virtual environment

error

This article etc. (This article is not bad because it is the same with other information) When starting Jupyter Notebook in a virtual environment, the following error There has occurred.

Procedure entry point
?PyWinObject_FromULARGE_INTEGER@@YAPEAU_object@@AEBT_ULARGE_INTEGER@@@z is the dynamic link library(Virtual environment path)\pythoncom37.Not found in dll

What I looked up and came out

Find the issues that encountered the same error.

https://github.com/ContinuumIO/anaconda-issues/issues/11502

It seems that the solution given by this is to replace pythoncom37.dll under System with pythoncom37.dll under Anaconda. This may solve it. (Unverified)

However, while reading this and trying it, I was interested in something else ...

The solution I did

Execute the following command in the virtual environment from the anaconda prompt.

conda install conda

It seems that conda was not included in the virtual environment. If you install conda with conda, it will work. Let's start it.

jupyter notebook

It is OK if it starts without any error.

By the way

In the first place, there is information that this error does not occur if you start jupyter Notebook from git bash or power shell (without going through anaconda prompt).
