Hints for Python & NodeJS install Variables on Windows

Reference images for windows 11 install of Python 3.11

• If you use the Pre-made binary windows version (releases page), you will not need to install Python or NodeJS.
• Below is for windows dev install only (download PineSAM-Sources-all._zip from Releases and install all dependency apps).
• once python/NodeJS is set up correctly, the PineSAM app starts up with no problem.
• dev install is for people who have issues with the premade binary package or wish to do development with pineSAM.

1. I had an issue originally because my Powershell terminal was pointing to old python 3.6 and not the newest 3.11.
2. I uninstalled all old versions of Python since I had 4 different versions installed (add/remove programs).
3. Then download & install the newest Python for windows (3.11 in this example).

1. Check box at the bottom, "Add python.exe to PATH", then choose "Customize installation"

2. Page 2, accept defaults works, looks similar to this.

3. Page 3, "Add Python to environment variables"

Note: If you "Install Python for all users," you do not need to "add python to environment variables," doing both is fine also on a home PC, which is what I did here.

### Python PATH

Check your windows PATH environment variable and be sure to include the Scripts directory of your Python installation. Recent versions of Python include a script to do this for you. Navigate to your Python installation directory (for example C:\Python311), open the Tools, then Scripts folder, and run the win_add2path.py file by double clicking on it. Alternatively, you can download the script here and run it with the command:

python win_add2path.py

If you don't want python to install to a hidden folder

• Another note is to check the box "install for all users" or install as administrator. If this is done then it will install to a regular location:
  c:\program files\python311\
• if this box is not checked, then it gets installed in a different hidden path.
• I simply installed it as "customized" and checked the box "install for all users" which put python 3.11 in the easier path of c:\program files\python311
  and not into my hidden folders (reference below)

Install Node.js

• NPM is included with Node.js, so you need to first install Node.js. You can download the latest version of Node.js from https://nodejs.org/en/download/

• During install, I checked the box to automatically install the necessary tools.

• Aftet clicking Finish, a terminal window will open.

Terminal window that opens, need to press any key like spacebar to continue. then press a key a second time.

Then it will open Powershell in admin mode.
