Installation
I must say this problem was driving me crazy for a long time, until I finally managed to pinpoint the source of the problem.
To install jupyter-renders we need to use:
jupyter labextension install @jupyterlab/plotly-extension
In the README.md it states that is required Node.js >= 5. However, my installation always halted in the following line:
@jupyterlab/plotly-extension@file:../extensions/jupyterlab-plotly-extension-0.16.0.tgz
Well, after sweat, tears, and pulling half of the hairs from my beard, I discover that the solution was using Node 6. Using Linuxbrew (and I presume that Brew under OSX is the same) is just a matter of unlinking Node, installing Node@6, and linking Node@6. Once installed you can return to any other Node version unlinking Node@6 and relinking the original one.
I hope this helps to other users with the same problem.
Well, I can definitely tell you that it doesn't work with Node 10.
I don't remember from the top of my head how to do it, but it's something like:
brew unlink node
brew install node@6 --force
brew link node@6 --force
And then install the extension.
If I knew this issue earlier I would have saved a lot of pain. Maybe yes, a change in the documentation would be great. Also, maybe someone with a bit of free time could test different Node versions.
EDIT:
This is the code:
brew unlink node
brew install node@6 --force
brew link --overwrite node@6 --force
At this point you should close the terminal or reboot the system before continuing.
jupyter labextension install @jupyterlab/plotly-extension
And now for restoring the original version of Node:
brew unlink node@6
brew link node
Again, closing the terminal or rebooting the system will be needed for preventing further problems.
With the code above, Node 6 is used for installing the extension, but the last version is restored once the process is completed.
I hope it helps.
Thanks for the info @realjumy 👍
I just tested installing @jupyterlab/plotly-extension with Node 10 and I had no issues... I use n to manage Node versions, so I'm not sure what it's doing different than homebrew, but I would recommend using it as it's dead-simple to work with and it doesn't seem to be causing issues. Nonetheless, you need to install Node initially in order to npm install n, so I think many people in the Python community using conda: conda install -c conda-forge nodejs .
In that case then the problem is caused by LinuxBrew. I have tried in 3 different computers, all with Linux Mint, and later with Ubuntu, and I always had issues. I will have to try with the alternative you're suggesting.
I am seeing this after all using Node 10. It seems to be an issue with yarn on Node 10. Downgrading to Node 9 resolved it for me.
Downgraded to Node 6 following the Brew method above and was able to successfully install the extension. Thanks @realjumy!!!
This is what the community is for. I'm glad you managed to make it run ;)
@gnestor I used Node 6 because at the moment of writing this, Linuxbrew was failing to install Node 9. But good to know that Node 9 can be used too :D
I'm unable to install this with Node 8.9 and Anaconda on Windows. (The permissions error occurs even after a restart).

@amellnik I have seen this error before but don't remember details. What command did you run to produce this?
@gnestor jupyter labextension install @jupyterlab/plotly-extension. The full error is:

Here's a similar issue: https://github.com/jupyterlab/jupyter-renderers/issues/127
Can you try stopping the jupyter server? Try running jupyter lab build?
@gnestor Sorry for the delay -- I missed the notification for your comment. I'm also not able to build lab now, and get an error related to the plotly extension:

Which version of Anaconda are you using? Recently I was having lots of problems with a clean installation of Anaconda3-5.2.0, which was making me unable to use Jupyter Lab. After trying clean installations a couple of times, I decided to install an older version (Anaconda3-5.1.0) and everything was absolutely fine.
The Module not found: Error: Can't resolve 'raw-loader' in 'C:\Users\amellnik\AppData\Local\Continuum\Anaconda3\share\jupyte r\lab\staging\node_modules\@jupyterlab\plotly-extension\lib' line suggests that the raw-loader module is not installed in the jupyterlab application directory which it should be. This is not affecting everyone so it's probably an environment issue. You can try force reinstalling jupyterlab. If that doiesn't help, try @realjumy's solution and downgrade or reinstall Anaconda.
I'm also seeing this bug. Would be nice to get it fixed since the current node version on conda is 10.x, so many people will get it. Downgrading to node 6 is not really a practical solution.
The other solution, suggested at https://github.com/jupyter-widgets/ipywidgets/issues/2061#issuecomment-397117346, is to manually install yarn and configure jupyter lab to use that. Works for me, but still not the most friendly approach for beginners.
Thanks for your suggestion @tiagopereira 👍 JupyterLab upgraded to yarn 1.7 and then ran into a bug and downgraded back to 1.6 because of a bug. I started the conversation back up at https://github.com/jupyterlab/jupyterlab/issues/4793.
Downgrading to node 6 is not really a practical solution.
Conda-forge packages node 9, which works well with jlab.
I'm unable to install this with Node 8.9 and Anaconda on Windows. (The permissions error occurs even after a restart).

I was able to resolve the same issue on Windows by downloading node 6 and replacing it in the path. Node 9 didn't work for me, but 6 did. You can get node 6 here: https://nodejs.org/download/release/v6.14.4/node-v6.14.4-win-x64.zip Extract it somewhere and put it in your path before your currently installed version, then try the install command. If you use a command line, try this to ensure it ends up in your path before your installed version:
C:\> set PATH=C:\nodejs6;%PATH%
(assuming of course that you extracted the zip file's nested folder to C:\nodejs6)
Hi, I faced the same issue. I followed the instruction of @darkniobe, I went a step further but I now have the following issue :
