C#, IronPython error: IronPython.Runtime.Exceptions.ImportException - No module named requests

Question

Using VS 2019 I installed the nuget packages IronPython v2.7.11 and DynamicLanguageRuntime v1.3.0 and am trying to run a python script. It ran fine until I added imports to the script:

import requests, time, socket
import random

Here’s the C#:

static void Main(string[] args)
{
    DateTime start = DateTime.Now;
    ScriptEngine engine = Python.CreateEngine();
    var searchPaths = engine.GetSearchPaths();
    // Path to where everything is installed for this Python enviroment
    searchPaths.Add(@"C:\Users\George\.conda\envs\spenv2");
    int url_id = 1701;
    string url = "https://www.yellowpages.com/search?search_terms=Health&geo_location_terms=Aliso+Viejo%2C+CA";
    ScriptScope scope = engine.CreateScope();
    engine.ExecuteFile(@"D:\Apps\Data Destinations\Scraping\ScrapeProjects\Job1.v4_For_IronPython_CSharp\ScrapeUrlPages.py", scope);
    dynamic testFunction = scope.GetVariable("scrape_all_pages_for_this_search");
    dynamic result = testFunction(url_id, url);
    Console.WriteLine(result);
}

I found a few posts regarding similar issues and the solution most of them was to add search paths. Which I did:

searchPaths.Add(@"C:\Users\George\.conda\envs\spenv2");

This is where everything is installed for the Python environment, spendv2, is being used. Any recommendations on what I need to do? Thank you.

Answer 1

I know that this is an old post, but I found something that works for me that can help in future questions about this.

1. I installed IronPython.StdLib from the NuGet Package.
2. I downloaded the needed library (Tkinter) with my IDE (PyCharm) and then I added the folder to the Lib folder in my C# project.
3. I added

   var libs = new[] {@"{PATH OF YOUR PROJECT}\Lib"};
   engine.SetSearchPaths(libs);
   

And that works for me.
