Current env var syntax won't be anymore supported by Docker and is currently blocking local development. ``` 3 warnings found (use docker --debug to expand): - LegacyKeyValueFormat: "ENV key=value" should be used instead of legacy "ENV key value" format (line 2) ``` <!-- CURSOR_SUMMARY --> --- > [!NOTE] > Use "ENV key=value" in generated Dockerfiles and add tests; minor devcontainer path string cast. > > - **Template/Dockerfile generation**: > - **JS SDK (`packages/js-sdk/src/template/index.ts`)**: Handle `ENV` instructions and output as `ENV key=value ...`. > - **Python SDK (`packages/python-sdk/e2b/template/main.py`)**: Same `ENV` formatting; also cast `devcontainer_directory` to `str` in devcontainer start command. > - **Tests**: > - **JS**: Add `toDockerfile` test covering `ENV` output. > - **Python (sync/async)**: Add tests for `ENV` output in generated Dockerfiles. > - **Changeset**: Patch releases for `@e2b/python-sdk` and `e2b`. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 4a9c504167dd8069551724d83bfa66f0859c1bd4.

What is E2B?
E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.
Run your first Sandbox
1. Install SDK
npm i @e2b/code-interpreter
2. Get your E2B API key
E2B_API_KEY=e2b_***
3. Execute code with code interpreter inside Sandbox
import { Sandbox } from '@e2b/code-interpreter'
const sbx = await Sandbox.create()
await sbx.runCode('x = 1')
const execution = await sbx.runCode('x+=1; x')
console.log(execution.text) // outputs 2
4. Check docs
Visit E2B documentation.
5. E2B cookbook
Visit our Cookbook to get inspired by examples with different LLMs and AI frameworks.
