mapview/mapedit installation on Google colab

[yoshida-gisc]

We would like to run a spatial analysis in Google Colab using the mapview/mapedit package. However, when trying to install the mapview/mapedit package via the install.package() function, it does not work, even following the manner below:

https://colab.to/r

system("apt-get -y update")
system("apt-get install -y libudunits2-dev libgdal-dev libgeos-dev libproj-dev")
install.packages("mapview")
library("mapview")

This codes are fine for the sf package following the issue (https://github.com/r-spatial/sf/issues/1946). However, it does not seem to be enough for the mapview/mapedit package.

Thanks in advances, Takahiro

Please give the entire output you see after giving the install.packages("mapview") command.

We run the code below in Google Colab.

system("apt-get -y update")
system("apt-get install -y libudunits2-dev libgdal-dev libgeos-dev libproj-dev")
install.packages("mapview")

Then, we faced the error message below. Note that we also faced time-out for running it (about 15 minutes).

We may need to install some system-dependecies. But, we cannot identify it ....

On a fresh colab notebook I can install sf, then mapview, but when loading mapview I get the following error:

htmltools is required by IRkernel, which essentially runs your colab, so cannot be unloaded; re-installing htmltools is possible but we can't load it because of this dependency. I don't see who needs htmltools >= 0.5.4, mapview doesn't say so in its DESCRIPTION.

I appreciate your prompt check! I faced the same error message. A feasible solution may be to wait for IRkernel to require htmltools 0.5.4 ...?

When installing the mapedit package, the same error message occurs.
