I'm using docker with python,when I need install some specific version of apps I docker remains me:
=> ERROR [3/3] RUN pip install cx-Oracle == 7.0.0 pandas == 1.1.2
my code in Dockerfile:
# Dockerfile, Image, Container
From python:3.7.9
ADD main.py .
Run pip install cx-Oracle == 7.0.0 pandas == 1.1.2
CMD ["python","./main.py"]
This has nothing to do with docker. pip install just does not like spaces between package name and version.
If you try pip install nonexistingpackage == 1.0.0 directly in the terminal you will get the error Invalid requirement: '==', before pip even checking if the package nonexistingpackage exists.
The reason is that pip install is using the whitespace as the delimiter between the different packages.
Remove the whitespaces:
RUN pip install cx-Oracle==7.0.0 pandas==1.1.2
