Launching Spyder and JupyterNotebook causes importError when image not found

Question

I'm new to python and the virtual environment stuff. I'm facing issues opening jupyter notebook and Spyder after updating conda.

Here are some info about the versions I have:

 $ conda info

JupyerNotebook version : 5.5.0
Jupyter version : 4.4.0
Spyder version : 3.2.8

Spyder fails to launch and when trying to launch spyder from anaconda navigator I get this error:

/anaconda2/lib/python2.7/site-packages/zmq/backend/cython/init.py", line 6, in from . import (constants, error, message, context, ImportError: dlopen(/Users/-/anaconda2/lib/python2.7/site-packages/zmq/backend/cython/error.so, 2): Library not loaded: @rpath/libsodium.23.dylib Referenced from: /Users/-/anaconda2/lib/libzmq.5.dylib Reason: image not found

Trying to launch jupyter notebook from anaconda throws the same image not found error:

/anaconda2/lib/python2.7/site-packages/zmq/backend/cython/init.py", line 6, in from . import (constants, error, message, context, ImportError: dlopen(/Users/-/anaconda2/lib/python2.7/site-packages/zmq/backend/cython/error.so, 2): Library not loaded: @rpath/libsodium.23.dylib Referenced from: /Users/-/anaconda2/lib/libzmq.5.dylib Reason: image not found

I found out that after updating, a new Anaconda2 folder was initialized for only the zmq file /anaconda2/lib/python2.7/site-packages/zmq/backend/cffi/__pycache__.

Everything was working smoothly but after following anaconda instructions and recommendations to update I started getting those errors.

How can I resolve this issue? Is it because the active environment : None?

Faced same issue. From https://github.com/jupyter/notebook/issues/1632 it explained that some dependencies when updating conda are messed up so try:

conda remove zeromq
conda install zeromq

Then try:

conda update conda-build

Good luck,
