python - Distributed 1.21.8 requires msgpack, which is not installed

Question

I'm having a problem trying to install plotly. I proceeded to upgrade anaconda using the command line on Debian 9 and I received the error message "distributed 1.21.0 requires msgpack, which is not installed".

Then I tried a conda install mspack, then a pip install --upgade plotly, and I get "distributed 1.22.0 requires msgpack, which is not installed". This 1.22.0 error message is what kicked off my whole upgrading process of many packages. Does this break plotly? Don't know, haven't tried but judging from msgpack website https://msgpack.org/, it is probable to cause errors. We'll see, I guess. Not sure what else to do.

pip install msgpack does not fix the problem

Answer 1

I face same issue while installing dask Later I resolved it using either of these two methods.

First Method: Run this command

conda install -c anaconda msgpack-python

Second Method: Run this command

pip install msgpack

Answer 2

I tried a few different ways to install this package, but none of them were successful.

Although some people might think it's because of the  ploty installation, it's not.

It could be the cause of the frustrating installation of Anaconda!

The installation or upgrading of any of the packages will not be impacted by the mistake.
