Trouble with php on express js

I am trying to get php working on my express js website using the php-express module. Unfortunatly, from what I’ve gathered and tried from what I could find online, I get the following error:

Error: Command failed: php mysitedirnode_modulesphp-expresslibPHPExpress/../../page_runner.php mysitedirStorage mysitedirStorageget_video_info.php
‘php’ is not recognized as an internal or external command,
operable program or batch file.

Here are some snippets from my express.js file:

var phpExpress = require('php-express')({
    binPath: 'php'
});

app.engine('php', phpExpress.engine);
app.all(/.+.php$/, phpExpress.router);

And then in my route for /get_video_info.php:

app.route("/")
    .all(async (req, res) => {
        console.log("weee");
        return await res.render(path.resolve('Storage','get_video_info.php'));
});
