Can't upgrade JupyterLab to latest version

Question

I am trying to upgrade JupyterLab to pre-release but when I check the installed version after upgrading I still get the old version (0.33.11).

To install the pre-release I used:

pip install -U --pre jupyterlab

I have also tried to upgrade to the latest version (0.35.6) using Anaconda:

conda install -c conda-forge jupyterlab

I also tried with this:

conda update jupyterlab

But again in all cases after installation I still get version 0.33.11.

When I run conda again I see that conda donwloads version 0.33.11. This is the message I get from it:

The following packages will be downloaded:

package                    |            build
---------------------------|-----------------
conda-4.6.14               |           py27_0         2.1 MB
jupyterlab-0.33.11         |           py27_0        10.0 MB
------------------------------------------------------------
                                       Total:        12.0 MB

Answer 1

conda install -c conda-forge jupyterlab=1.0.2

Solve the problem for me.
