After using that now I am having the following error

remove the compression plugin for webpack compression-webpack-plugin and install again

[ernitingoel]

What impact it will be having on the functionality?

[PatrickJS]

you need to remove the compression-webpack-plugin from prod as well. the impact is that the files won't be compressed

[aminebizid]

We solved it by installing Python x86 version between 2.5 and 3.0 on windows

[ernitingoel]

FYI, for node-gyp related error, please make sure it met the requirements as mentioned in

https://github.com/nodejs/node-gyp

[dsebastien]

node-gyp on Windows is a nightmare :)
Most of the time, just running npm install --no-optional avoids the issue entirely as node-gyp is often requested through optional dependencies

[PatrickJS]

I removed the compression-webpack-plugin to avoid errors in osx and windows

[AndreiSoroka]

me helped: apt-get install build-essential
p.s. linux

[pthibodeaux]

I am getting the same errors in Windows. I tried several suggestions from above, but still no success

[pthibodeaux]

I see notes that you should "you need to remove the compression-webpack-plugin from prod as well. the impact is that the files won't be compressed"
How do you do this?
