Uninstalling CRAN packages mistakenly loaded in Jupyter

[1rdsk1]

Hi Mingwandroid Thank for your advice at https://github.com/ContinuumIO/anaconda-issues/issues/777 So I now need to uninstall the CRAN packages I installed in Jupyter but I find I cannot get the R kernel to start due to the error described in link. Is there another way to remove the CRAN packages I mistakenly installed. Also, how should I install HTTR using conda please? Rupert

You need to use R from the command line. Activate your environment and type R

Then to install r packages, again, from the command line:

conda install -c r r-httr.

You can use conda search -c r <partial-name> to search for packages. All of the r packages start with r- and many with r-r.

Thanks. I uninstalled the CRAN packages and rebooted pc but still get the missing dll errors. Do I need to do a complete reinstall of Annaconda to start afresh or can I fix Jupyter R dll error some other way please? Rupert

I would probably recommend that yes, but first, try launching jupyter notebook from the Anaconda Prompt.

launching jupyter notebook from the Anaconda Prompt seems to work. Odd since presumably the menu points to same executable, Hope to figure that out.

I cant find how to do a reinstall of Annaconda, How do I do that if this fails in a bit please? Just in case ... Rupert

Well, it's probably to do with PATHs then. If you were to launch anaconda-navigator from the Anaconda Prompt can you see if you can then launch Jupyter from that successfully?

I believe the shortcut for Anaconda Navigator may need to work more like the one for Anaconda Prompt and this is something for me to investigate.

I wouldn't be too concerned about reinstalling everything though, but you can either remove Anaconda from the Control Panel or just delete the folder and then re-run the installer.

Hi,

I'll have to now see if its possible to get the webscrapers httr and xml R packages via conda. Fingers crossed although I suspect I'll get same R version issues, Hopefully conda will manage that soon too! Jupyter from anaconda-navigator from the Anaconda Prompt worked with below messafes. Also the Jupyter icon disappeared from navigatotor after launch FYI, I tried to paste images and list errors below. Many thanks

[mingwandroid]

I told you already how to get the r packages from conda. We have the packages at the right versions.

[mingwandroid]

The incorrect sRGB profile thing is nothing to worry about and the disappearing icon is known.

The disappearing icon is fixed on the latest version coming soon.

Great!
