Error "Invalid comparison operator in dependency: >=" when installing R package from GitHub

I'm trying to install package "webr" from GitHub in R (v3.5.3) and get this error:

devtools::install_github("cardiomoon/webr")

> Downloading GitHub repo cardiomoon/webr@master
>
> Error in FUN(X[[i]], ...) :

>  Invalid comparison operator in dependency: >=

I could install 'webr' from CRAN repository without errors, but I need it from GitHub, because otherwise it does not contain the "PieDonut()" function to make these beautiful plots:

The error seems to go back to some leading whitespaces in older "devtools" versions.

https://github.com/r-lib/devtools/issues/1247

I'm using the latest "devtools" package (v2.0.2) installed from CRAN repository, where this problem should be solved already.

Any ideas?

There was a small issue in their DESCRIPTION file. I fixed this and wrote a pull request. Until they accept the PR or fix the problem themselves, you can install the package from my fork:

devtools::install_github("JBGruber/webr")

Update

Should be fixed. devtools::install_github("cardiomoon/webr") should work now.
