How to install package in Dockerfile by using Python -m pip install

Question

I am installing Onnxruntime-extensions from official git repo but fail in Dockerfile:

the packages are not ready yet, so it could be installed from source. Please make sure the compiler toolkit like gcc(later than g++ 8.0) or clang, and the tool cmake are installed before the following command

python -m pip install git+https://github.com/microsoft/onnxruntime-extensions.git

Dockerfile

• this is not working.

RUN python -m pip install git+https://github.com/microsoft/onnxruntime-extensions.git

Answer 1

Perhaps use python3 instead of python .

Answer 2

Python is not installed (checked both python and python3 ). Install it with apt or apt-get
apt-get update && apt-get install -y python3.8 python3-pip
