在本地运行Docker lambda图像

这是Dockerfile：

FROM lambci/lambda:build-python3.6 # Copy in your requirements file ADD requirements.txt /requirements.txt # Copy your application code to the container RUN mkdir /code/ WORKDIR /code/ ADD . /code/ ENV PS1 'zappa@$(pwd | sed "s@^/var/task/\?@@")\$ ' ADD zappa_settings.json /var/task/zappa_settings.json WORKDIR /var/task RUN virtualenv /var/venv && \ source /var/venv/bin/activate && \ pip install -U pip zappa && \ pip install -r /requirements.txt && \ deactivate CMD ["zappa"] 

但是，当我运行docker-compose up我得到：

 Recreating basesite_web_1 ... Recreating basesite_web_1 ... error ERROR: for basesite_web_1 Cannot start service web: oci runtime error: container_linux.go:262: starting container process caused "exec: \"zappa\": executable file not found in $PATH" ERROR: for web Cannot start service web: oci runtime error: container_linux.go:262: starting container process caused "exec: \"zappa\": executable file not found in $PATH" ERROR: Encountered errors while bringing up the project. 

我认为这是因为我需要激活virtualenv。 我希望能够在本地机器上运行项目进行开发。 我错过了什么？ 谢谢！
