PocketSphinx install can't find swig.exe

Question

I have searched all over the web and especially have gone through all the questions regarding this here on Stackoverflow.

I am using the following command to install it "pip install pocketsphinx"

I have windows x64, I have not set any environmental paths regarding Swig.

Also I've downloaded Swig zip file and extracted it into my downloads folder, searched through it and there is no "swig.exe" file.

Below you can see the error/log from the command prompt.

This lacks detail and I have no idea how that would make it detectable. I may be close to a solution and will update when and if it works. — John Smith, Jan 13 '18 at 13:09

Alright, I solved it. Here’s how:

First I went to their official website and downloaded the swigwin file specifically for windows with a “swig.exe” file.

Then I extracted it, and added it to the environment variable PATH. This solved my problem.

Afterwards I got another error, it couldn’t find visual studio C++ build tools v14.0 (along these lines), if you have this problem too just, download the C++ build tools 2015 from their official website, install, then find it in your Program Files or what ever, copy the path to the VC folder and add it to your environment variable PATH as well.

This allowed me to download/install pocketsphinx on windows.

First run your IDE or CMD as Administrator and run the following:

pip install pipwin
pipwin install pocketsphinx
