Missing files and folders in zip

[Joshua-Miron]

After installing on Windows, following the instructions to the letter, run I run the software in PowerShell using python run.py I then open a browser (Firefox), enter localhost:5000) and I get the following error in PowerShell:

PS C:\Users\[USER]\Desktop\lexos> python run.py

Many of the files referenced weren't installed from the downloaded ZIP file. For example, there is no
C:\Users[USER]\Desktop\Lexos\lexos\frontend\node_modules\

The install doesn't seem to be accurate anymore. Or at least, the zip doesn't contain files and folders referenced in the above code

This looks like an oversight to me. We'll try to find a fix, but, in the meantime, the workaround below might do:

1. Download and install Node.js.
2. From the command line, run npm install npm@latest -g to ensure that you have the latest version of npm.
3. Change directories to the Lexos frontend directory (something like cd {path_to_lexos}/Lexos/lexos/frontend).
4. Run npm install.

This should download all the Javascript dependencies (which appears to be what's missing) into the node_modules folder.

[scottkleinman]

Correction. The procedure is documented in the Windows Install Guide under Starting and Launching _Lexos. Here is the text:

Now navigate to the frontend folder by typing cd Desktop/Lexos/lexos/frontend and hit the Enter key. Type npm install and hit Enter key. If you do not have npm installed follow the instructions here to download npm and Node.js.

After the installation if npm install yields the error npm is not recognized as an internal or external command, restart your computer.

We might need more subheadings in the documentation to make this stand out more.

Thank you for your response. Prior to posting, I had installed node.js following the instructions. I also tested that they were installed with the following:

PS C:\Users\jmiron\Desktop> node -v
v22.14.0
PS C:\Users\jmiron\Desktop> npm -v
10.9.2
PS C:\Users\jmiron\Desktop>

The issue I described above occurred after this installation and test. I tried reinstalling from within the frontend folder as you mention and received this error:

PS C:\Users\jmiron\Desktop\lexos\lexos\frontend> npm install

Forgive me for not understanding the issue here.
