I'm trying to set a Local Development Server for Lightning Web Components according to this link but when I try to install the plugin @salesforce/lwc-dev-server I get this error message :

The instructions for setting up an Angular application project are straightforward. I have had no issue with setting up and running Stryker on an application project using default settings for Karma. I am having trouble getting it to work correctly when it is a Library project instead, however.

I have looked through the configuration documentation for Stryker and I have tried adjusting the paths to the relevant files (for mutation and the karma.config)

stryker.conf.json

This happened on node version 14.16.0. I encountered the error twice now. The first time i created a react component with the @mui/lab/DateTimePicker.
I didn't have to install it since @mui/lab was already existing in the project. (tried to reproduce this on another branch(very few changes apart). Didn't work so probably has nothing to do with mui itself)
The second time was also the second approach to the time input component. Using another simpler node module which i had to install this time. (also couldn't reproduce this case) (worked like a charm the second time)

I was following this video and when I try to create a react application on my system by using the following command

I am practicing Angular following a book project which requires the installation of the Clarity library for the project through cmd ng add @clr/angular but I keep getting an error (report) relating to incompatibilties:

I have been getting the following error in my CodeBuild execution: ModuleNotFoundError: No module named 'cfn_tools'

Interesting note, the first time I ran this through CodeBuild with this module I had no issues. It only started happening after I made my next gitHub push that kicked off my pipeline that I saw this. The files that are related to this didn't change, and the modifications in that next push were to an unrelated section of the repo.

I have since tried to do:

• pip install cfn-tools & pip3 install cfn-tools which mentioned that the module was already installed. These were added to the BuildSpec section. No success - still got the error
• I've added a requirements.txt file with no success still got the error. I created this file using pip freeze also within the BuildSpec. The module shows up, but still get the error.
• Originally used runtime version 3.7 of python and then tried with 3.9 which still didn't work.

python runtime 3.9 Any assistance would be appreciated.

UPDATE: To add more information I download a .tar.gz file from S3 that contains the python scripts I need for running in this build. I extract the .tar.gz then I run the script that is having the error. Here is the output for when I install cfn-tools and do a pip freeze You will see below that cfn-tools loads and is part of the output of pip freeze but yet when I run my script it give me the above error.

I've installed nvm for windows and nvm list shows
