Missing separator error using R 3.5.0 on Windows 64

[aadler]

I'm trying to install the package from source on Windows 7 64bit for R 3.5.0 using Rtools 3.5, and I'm getting the following error:

install.packages('httpuv', type = 'source', INSTALL_opts = '--byte-compile --clean --resave-data --compact-docs')

Warning message:

I get this using both RStudio (447) and the GUI console.

Thanks.

Shoot, it looks like that line has spaces instead of a tab: https://github.com/rstudio/httpuv/blob/v1.4.1/src/Makevars.win#L28

Can you try installing without the --clean flag?

Doesn't help.

Confirming that installing 8a28cdb from devtools works. Thanks!
