Code Interpreter SDK Beta - Language Runtimes

This guide shows how to run AI-generated code in different language runtimes using the new Code Interpreter beta SDK. The following language runtimes are currently supported:

  • Python
  • JavaScript
  • Java
  • Bash
  • R

Want more language runtimes? Reached out to us on Discord or over email.

1. Install the Code Interpreter beta SDK

The latest beta versions you should install can be found in NPM/PyPi release history:

  • JavaScript & TypeScript
  • Python

2. Active kernel for the desired language

Each of the supported language runtimes has its own kernel.

Python

from e2b_code_interpreter import CodeInterpreter

sandbox = CodeInterpreter()

# 1. Set JS kernel - available kernel names: 'r', 'javascript', 'java', 'bash'
js_id = sandbox.notebook.create_kernel(kernel_name="javascript")
# 2. Run JS code inside code interpreter!
execution = sandbox.notebook.exec_cell("console.log('Hello World!')", kernel_id=js_id)
print(execution)
# 3. Use Python again
sandbox.notebook.exec_cell("print('Hello World!')")

JavaScript / TypeScript

import { CodeInterpreter } from '@e2b/code-interpreter'

const sandbox = await CodeInterpreter.create()

// 1. Set JS kernel - available kernel names: 'r', 'javascript', 'java', 'bash'
const jsID = await sandbox.notebook.createKernel({ kernelName: 'javascript' })
// 2. Run JS code inside code interpreter!
const execution = await sandbox.notebook.execCell("console.log('Hello World!')", { kernelID: jsID })
console.log(execution)
// 3. Use Python again
await sandbox.notebook.execCell('print("Hello World!")')
