快速开始

E2B 快速开始

参考 https://e2b.dev/docs/quickstart

准备

用本地 linux 机器测试, 我用的是 linux mint 22,底层是 ubuntu 22.04.

帐号和key

用 github 账号登录 https://e2b.dev/

创建新的 key, 保存下来, 设置环境变量:

export E2B_API_KEY=e2b_d65e814d15c37858xxxxxxxx

安装 python sdk

参考: https://pypi.org/project/e2b/

pip install e2b-code-interpreter python-dotenv

安装 nodejs sdk

参考: https://www.npmjs.com/package/e2b

npm i @e2b/code-interpreter dotenv

简单运行

python 运行

mkdir -p ~/work/code/e2b/quickstart-python
cd ~/work/code/e2b/quickstart-python

新建一个 python 文件:

vi e2b-quickstart.py

内容如下:

from dotenv import load_dotenv
load_dotenv()
from e2b_code_interpreter import Sandbox

sbx = Sandbox() # By default the sandbox is alive for 5 minutes
execution = sbx.run_code("print('hello world')") # Execute Python inside the sandbox
print(execution.logs)

files = sbx.files.list("/")
print(files)

执行:

python e2b-quickstart.py

输出为:

Logs(stdout: ['hello world\n'], stderr: [])
[EntryInfo(name='.e2b', type=<FileType.FILE: 'file'>, path='/.e2b'), EntryInfo(name='bin', type=<FileType.FILE: 'file'>, path='/bin'), EntryInfo(name='boot', type=<FileType.DIR: 'dir'>, path='/boot'), EntryInfo(name='code', type=<FileType.DIR: 'dir'>, path='/code'), EntryInfo(name='dev', type=<FileType.DIR: 'dir'>, path='/dev'), EntryInfo(name='etc', type=<FileType.DIR: 'dir'>, path='/etc'), EntryInfo(name='home', type=<FileType.DIR: 'dir'>, path='/home'), EntryInfo(name='ijava-1.3.0.zip', type=<FileType.FILE: 'file'>, path='/ijava-1.3.0.zip'), EntryInfo(name='install.py', type=<FileType.FILE: 'file'>, path='/install.py'), EntryInfo(name='java', type=<FileType.DIR: 'dir'>, path='/java'), EntryInfo(name='lib', type=<FileType.FILE: 'file'>, path='/lib'), EntryInfo(name='lib64', type=<FileType.FILE: 'file'>, path='/lib64'), EntryInfo(name='lost+found', type=<FileType.DIR: 'dir'>, path='/lost+found'), EntryInfo(name='media', type=<FileType.DIR: 'dir'>, path='/media'), EntryInfo(name='mnt', type=<FileType.DIR: 'dir'>, path='/mnt'), EntryInfo(name='opt', type=<FileType.DIR: 'dir'>, path='/opt'), EntryInfo(name='proc', type=<FileType.DIR: 'dir'>, path='/proc'), EntryInfo(name='r-4.4.2_1_amd64.deb', type=<FileType.FILE: 'file'>, path='/r-4.4.2_1_amd64.deb'), EntryInfo(name='requirements.txt', type=<FileType.FILE: 'file'>, path='/requirements.txt'), EntryInfo(name='root', type=<FileType.DIR: 'dir'>, path='/root'), EntryInfo(name='run', type=<FileType.DIR: 'dir'>, path='/run'), EntryInfo(name='sbin', type=<FileType.FILE: 'file'>, path='/sbin'), EntryInfo(name='srv', type=<FileType.DIR: 'dir'>, path='/srv'), EntryInfo(name='swap', type=<FileType.DIR: 'dir'>, path='/swap'), EntryInfo(name='sys', type=<FileType.DIR: 'dir'>, path='/sys'), EntryInfo(name='tmp', type=<FileType.DIR: 'dir'>, path='/tmp'), EntryInfo(name='usr', type=<FileType.DIR: 'dir'>, path='/usr'), EntryInfo(name='var', type=<FileType.DIR: 'dir'>, path='/var')]

nodejs 运行

mkdir -p ~/work/code/e2b/quickstart-nodejs
cd ~/work/code/e2b/quickstart-nodejs

新建一个 nodejs 文件:

vi e2b-quickstart.ts

内容如下:

import 'dotenv/config'
import { Sandbox } from '@e2b/code-interpreter'

const sbx = await Sandbox.create() // By default the sandbox is alive for 5 minutes
const execution = await sbx.runCode('print("hello world")') // Execute Python inside the sandbox
console.log(execution.logs)

const files = await sbx.files.list('/')
console.log(files)

执行:

npx tsx ./e2b-quickstart.ts

报错:

npx tsx ./index.ts           

node:internal/modules/run_main:123
    triggerUncaughtException(
    ^

这个错误是因为在使用 CommonJS (cjs) 格式的模块时，在顶层使用了 await，而 CommonJS 不支持顶层 await。

修改目录下的 package.json, 添加 "type" : "module":

{
  "type" : "module",
  "dependencies": {
  }
}

再次执行:

npx tsx ./e2b-quickstart.ts

输出为:
