Installing sqlite3 as a node.js module

Question

So I've been working on this since yesterday, and can't seem to get anywhere. I've tried to follow documentation, and various tutorials but none of them seem to work.

If I make a new folder, with a new Javascript file with the default usage code:

var sqlite3 = require('sqlite3').verbose();
var db = new sqlite3.Database(':memory:');

db.serialize(function() {
  db.run("CREATE TABLE lorem (info TEXT)");

  var stmt = db.prepare("INSERT INTO lorem VALUES (?)");
  for (var i = 0; i < 10; i++) {
      stmt.run("Ipsum " + i);
  }
  stmt.finalize();

  db.each("SELECT rowid AS id, info FROM lorem", function(err, row) {
      console.log(row.id + ": " + row.info);
  });
});

db.close();

And then try to install sqlite3 through npm by typing into the node.js CMD:

cd C:\Users\User\Desktop\Sqlite3test 
npm install sqlite3

I'm greeted with this error message:

Looking further through the documentation on the NPM website regarding sqlite3, it says that I must meet " node-gyp's requirements ". I have gone through and done all of these. If I set up the python environment beforehand using:

npm config set python C:\Python27\python.exe

I get the same error message. I have no idea what's going on. Could it be because Windows 10 currently doesn't support the node-gyp requirements?

Answer 1

由于您使用的是Windows，请尝试

set PYTHON=python2.7

Answer 2

Okay, so I found the solution.

It turned out that my Python environment variable was not correctly set. I looked it up on another thread and found this solution posted by Delicia Brummitt:
