python ImportError: cannot import name 'open_code' from 'io'

I faced python errors:

1. First error:
   
   Fatal Python error: init_sys_streams: can't initialize sys standard streams
   Traceback (most recent call last):
     File "/home/user/miniconda3/envs/py38/lib/python3.8/io.py", line 54, in <module>
   ImportError: cannot import name 'open_code' from 'io' (unknown location)
   Aborted (core dumped)
   This error comes from the fact that there are two different versions of Python conflicting with each other.
   
   
2. Second error:
   

tack Error: Command failed: E:\ProgramData\Anaconda3\python.EXE -c import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack   File "<string>", line 1

This error because it required old version of python 2.7

To solve these errors we need to install multiple versions of python and switch between them

You can install from:
https://nvm-for-windows.software.informer.com/

You can use this command to install python version
nvm install v6.11.4

You can use this command to list all python versions

nvm list

You can use this command to set default version

nvm use v6.11.4

MSBUILD error

I have tried the troubleshooting steps for installing node-sass. But it did not work fine. It did not installed the node-sass and generated errors.

  E:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\Microsoft.CppBuild.targets(390,5): error MSB8020: The build tools for Visual Studio 2017 (Platform Toolset = 'v141') cannot be found. To build using the v141 build tools, please install Visual Studio 2017 build tools.  Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting "Retarget solution". [E:\Code\Liferay\com-liferay-commerce-7.1.x\commerce-bom-admin-web\node_modules\node-sass\build\src\libsass.vcxproj]
 

Install all the required tools and configurations using Microsoft's windows-build-tools by running:

npm install -g windows-build-tools  (install msbuild visual studio 2017)




set msbuild visual studio 2017 set as default:


npm config set msbuild_path "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe"




After that my problem was solved
