Fix E2B package install failure

Q: Fix E2B package install failure

To fix e2b package install failures, ensure you install the correct package e2b-code-interpreter via pip install e2b-code-interpreter. Avoid installing a non-existent package named e2b, which causes errors.

Quick answer

To fix e2b package install failures, ensure you install the correct package e2b-code-interpreter via pip install e2b-code-interpreter. Avoid installing a non-existent package named e2b, which causes errors.

PREREQUISITES

Python 3.8+
pip 22+
Internet connection for pip install

Setup

Install the correct e2b-code-interpreter package using pip. The common mistake is trying to install e2b, which does not exist on PyPI.

Set your E2B_API_KEY environment variable before running code that uses the sandbox.

bash

pip install e2b-code-interpreter

output

Collecting e2b-code-interpreter
  Downloading e2b_code_interpreter-1.0.0-py3-none-any.whl (15 kB)
Installing collected packages: e2b-code-interpreter
Successfully installed e2b-code-interpreter-1.0.0

Step by step

Use the Sandbox class from e2b_code_interpreter with your API key from environment variables. Run code inside the sandbox and print the output.

python

import os
from e2b_code_interpreter import Sandbox

sandbox = Sandbox(api_key=os.environ["E2B_API_KEY"])
execution = sandbox.run_code("print('Hello from sandbox')")
print(execution.text)
sandbox.close()

output

Hello from sandbox

Common variations

You can upload files to the sandbox using sandbox.files.write(filename, data) and install packages inside the sandbox by running pip commands via run_code. The package is synchronous; async usage is not supported.

python

sandbox.files.write("data.csv", open("local.csv", "rb").read())
sandbox.run_code("import subprocess; subprocess.run(['pip','install','pandas'])")

Troubleshooting

If pip install e2b fails, switch to pip install e2b-code-interpreter.
Ensure your Python version is 3.8 or higher.
Set the E2B_API_KEY environment variable correctly before running code.
If you get import errors, verify the package is installed in the correct Python environment.

✅

Key Takeaways

Always install the package with pip install e2b-code-interpreter, not e2b.
Set E2B_API_KEY environment variable before using the sandbox.
Use Sandbox.run_code() to execute code safely inside the sandbox.
Check Python version and environment if installation or import fails.
