This is a copy of an [issue](https://stackoverflow.com/questions/63581759/jupyterlab-extension-install-for-plotly-4-9-0-fails) I posted on Stack Overflow, but now that I’ve found these forums I’ll repost here. I’m trying to install Plotly for use within a Jupyter Lab environment using the instructions from Plotly’s web site [Instructions](https://plotly.com/python/getting-started/). I’m installing on top of a fresh Anaconda 64-bit install on a Windows 10 OS. The following install commands all worked correctly ```auto conda install -c plotly plotly=4.9.0 conda install "notebook>=5.3" "ipywidgets>=7.2" conda install jupyterlab "ipywidgets=7.5" ``` I also installed nodejs using: ```auto conda install nodejs ``` But when it comes time to do the Jupyter Lab specific stuff then this fails ```auto jupyter labextension install jupyterlab-plotly@4.9.0 An error occured. ValueError: "jupyterlab-plotly@4.9.0" is not a valid npm package See the log file for details: C:\Users\tj\AppData\Local\Temp\jupyterlab-debug-cm_yk8nr.log ``` The log file says the following: ```auto Node v10.13.0 Yarn configuration loaded. > C:\Users\tj\Anaconda3\npm.CMD pack jupyterlab-plotly@4.9.0 npm WARN registry Unexpected warning for https://registry.npmjs.org/: Miscellaneous Warning SELF_SIGNED_CERT_IN_CHAIN: request to https://registry.npmjs.org/jupyterlab-plotly failed, reason: self signed certificate in certificate chain npm WARN registry Using stale package data from https://registry.npmjs.org/ due to a request error during revalidation. npm ERR! code ETARGET npm ERR! notarget No matching version found for jupyterlab-plotly@4.9.0 npm ERR! notarget In most cases you or one of your dependencies are requesting npm ERR! notarget a package version that doesn't exist. npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\tj\AppData\Roaming\npm-cache\_logs\2020-08-25T14_44_35_633Z-debug.log ``` So all indications to me are that it thinks it can’t find the nodejs package called jupyterlab-plotly. If I go to the NPM site I can find the package [jupyterlab-plotly](https://www.npmjs.com/package/jupyterlab-plotly) which indicates it’s version 4.9.0. It’s not clear to me where I’ve gone wrong. Has anyone successfully followed these steps and gotten plotly to work properly in a Jupyter Lab environment? ---

With the release of plotly 4.10 this issue still continues to happen. The command ``` jupyter labextension install jupyterlab-plotly@4.10.0 ``` still fails in a similar manner with the error message ``` An error occured. ValueError: "jupyterlab-plotly@4.10.0" is not a valid npm package See the log file for details: C:\Users\tj\AppData\Local\Temp\jupyterlab-debug-xbf4irk3.log ``` and the log file contains info similar to the original one I posted. ---

I made some progress on this . From my Anaconda prompt I issued a ``` npm config set registry http://registry.npmjs.org/ ``` command. Then I ran ``` jupyter labextension install jupyterlab-plotly@4.10.0 ``` which again failed. Looking at it’s debug log things made some progress. It at least found the npm package but when trying to install it we had another issue: ``` Node v10.13.0 Yarn configuration loaded. Building jupyterlab assets (build:prod:minimize) > node C:\Users\tj\Anaconda3\lib\site-packages\jupyterlab\staging\yarn.js install --non-interactive yarn install v1.21.1 [1/5] Validating package.json...

So I then ran ``` npm install plotly.js ``` which looks like it succeeded. ``` npm WARN saveError ENOENT: no such file or directory, open 'C:\Users\tj\package.json' npm WARN enoent ENOENT: no such file or directory, open 'C:\Users\tj\package.json' npm WARN tj No description npm WARN tj No repository field. npm WARN tj No README data npm WARN tj No license field. + plotly.js@1.55.2 added 453 packages from 166 contributors and audited 454 packages in 30.7s found 0 vulnerabilities ``` But another round of ``` jupyter labextension install jupyterlab-plotly@4.10.0 ``` still fails with the debug log saying again that it can’t find plotly.js (same as above). ---

I have this problem all the time. I have written a read me to help me install plotly on jupyterlab. I’m going to paste it below. Hopefully it will be helpful for you. I don’t usually use an anaconda environment, but I think this should work there as well. I’m on a MAC for what it’s worth. #####installing plotly for jupyter lab #check the version of jupyter lab with jupyter --v #jupyter lab should be \> 1.2 pip install “ipywidgets==7.5” #Need to install nodejs and npm #first install npm touch ~/.bash\_profile curl -o- [https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh](https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh) | bash #and activate it . ~/.nvm/nvm.sh #now use NPM to install nodejs nvm install 13.12.0 #configure the jupyter lab extensions needed to use plotly #use this to manage out of memory errors export NODE\_OPTIONS=–max-old-space-size=4096 #install the wigest extension jupyter labextension install @jupyter-widgets/jupyterlab-manager --no-build #install the figurewiget jupyter labextension install plotlywidget@1.5.0 --no-build #rendering support jupyter labextension install jupyterlab-plotly --no-build #build the extensions jupyter lab build #unset the node options unset NODE\_OPTIONS ---

> [@BagOfDoorknobs](#): > > `jupyter labextension install jupyterlab-plotly@4.10.0` Thanks for the info. I was about to walk through your process when I made a last ditch attempt to run ``` jupyter labextension install jupyterlab-plotly@4.10.0 ``` This time it worked. The only difference is that instead of being attached to my internal corporate network I was attached via VPN. Apparently there’s a difference in the firewalls. I’ll mark this as closed for now. ---

Your process worked for me, except that I got an error on the lab build: `error icss-utils@5.1.0: The engine "node" is incompatible with this module. Expected version "^10 || ^12 || >= 14".` I switched to 12.22.1 (nvm install 12.22.1) and then it worked. Thanks!
