Install packages that need to be compiled with Python3 with pip [Windows]
For example, if you use a package called pycrypto on Windows, you need to compile it, so even if you normally type pip install pycrypto, an error will be returned.
Therefore, compile using the Visual Studio Build Tool and then perform the installation work.
Installing the Visual Studio Build Tool requires some space, but the task itself is very easy.
- Windows 10 --Anaconda installed
Build a virtual environment
Since it is just a trial operation, we will temporarily create and use a virtual environment. Run as administrator at the command prompt.
#Build a virtual environment
# conda create -n Virtual environment name python=3.5.3
conda create -n wxenv python=3.5.3
#When creating with a set of Anaconda
# conda create -n wxenv python=3.5.3 anaconda
#When checking the created environment
# conda info -e
# conda list -n wxenv
#When deleting the created virtual environment
# conda remove -n wxenv --all
