I’m on mac OSX and deploying a python lambda on AWS.

I have created a local env source venv/bin/activate following these instructions.

> **[How to Handle your Python packaging in Lambda with Serverless plugins](https://www.serverless.com/blog/serverless-python-packaging/)**
>
> Handling Python dependencies in your Lambda functions can be a pain. Here's how I handle Python packaging with Serverless for dev/prod parity.

I have installed all of the packages

```
$ pip install numpy

Requirement already satisfied: numpy in ./venv/lib/python3.5/site-packages (1.14.2)

```

then i deploy the package using

```
pip freeze > requirements.txt

serverless deploy 

```

**error when running on the lambda**

> START RequestId: ################### Version: $LATEST  
> Unable to import module ‘ **main** ’: Missing required dependencies [‘numpy’]

Also note: my code is not calling numpy, it’s calling quandl and quandl is calling numpy

**requirements.txt**

can you redo all steps within `virtualenv`?
