Error: ImportError: cannot import name 'Aer' from 'qiskit' with Ananconda Linux about qiskit-aer HOT 4 CLOSED

@claudefalbriard You need to follow the build instructions for building and install Aer from source if you are installing from the git repo. Otherwise use pip install qiskit-aer to install pre-built wheels.

from qiskit-aer.

Thanks @chriseclectic . Got a working installation using the basic pip installation process. I've corrected it with the pip uninstall & install procedure. Important was to add the packages in the following sequence:
pip uninstall qiskit-chemistry
pip uninstall qiskit-aqua
pip uninstall qiskit-terra
pip uninstall qiskit-aer
pip uninstall qiskit
pip install qiskit # (also installs aer and terra)
pip install qiskit-aqua
pip install qiskit-chemistry

In the sample, there also was a slight change in the module names of aqua components, needed to be adjusted at the chemistry sample (qiskit.aqua.components now are qiskit_aqua.components).

Glad you got it working!
