problems installing pandas module with pip on mac

Question

I have 2 python installations on my mac osx.

$ which python
/usr/bin/python

$ which python3
/Library/Frameworks/Python.framework/Versions/3.4/bin/python3

$ pip install --upgrade setuptools

$ which pip

$ pip -V
pip 18.1 from /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/pip (python 3.4)

I can install modules with pip fine. for example $ python3 -m pip install --user tensorflow Successfully installed absl-py-0.6.1 astor-0.7.1 gast-0.2.0 grpcio-1.17.1 markdown-3.0.1 protobuf-3.6.1 tensorboard-1.12.1 tensorflow-1.12.0 termcolor-1.1.0 werkzeug-0.14.1

but when i try the same with pandas $ python3 -m pip install --user pandas

it goes through till the end by collecting and downloading dependencies, but errors out with the following error.

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/d5/k1w6m6xj5g727x952sdkkc1r0000gn/T/pip-install-r4n38agj/pandas/

The issue seems to be that it is using Python where it should be using python3 in python setup.py egg_info

how do i make sure that pip uses python3 in the scripts or if there is any other issues ?

Answer 1

You can use any code given below

pip3 install pandas --no-build-isolation

OR

sudo apt-get install python3-pip
sudo -H pip3 install pandas

OR

sudo pip install pandas

OR

pip install --user pandas

and for mac terminal using mojave works like

pip3 install pandas

or

pip 3 install --upgrade pip

after

pip install pandas
