Question

Unfortunately when using the Docker base: continuumio/miniconda3:4.9.2 from https://hub.docker.com/r/continuumio/miniconda3 and running: pip install PyICU==2.4.2 I get this error:

I have tried to install these packages as well however have had no luck:

RUN apt-get update
RUN apt-get install -y sudo build-essential pkg-config gcc awscli jq vim 

Does anyone know what config I am missing / what packages I need to add?

PyICU is a Python wrapper around the C++ ICU library. You need to install said library first:

apt-get install libicu-dev
