error when running devtools::install_deps('something', Ncpus = 2)

[robkooper]

When running devtools::install_deps(Ncpus = 2) it shows an error (see https://travis-ci.org/PecanProject/pecan/jobs/587707337#L2489).

Error: 1 components of `...` were not used.
We detected these problematic arguments:
* `Ncpus`
Did you misspecify an argument?
Backtrace:

The command "scripts/travis/script.sh" exited with 1.

I believe that internally it uses install.packages which does support the Ncpus argument. This used to work in the past, but now breaks the Travis builds.

I'm basing this on the documentation found at: https://www.rdocumentation.org/packages/devtools/versions/2.2.0/topics/install_deps

This should be fixed with the current CRAN version of devtools, you seem to be using an older version. The current CRAN version was released on September 24th.

@jimhester can you please have another look at this? I can still see the reported behavior both with devtools 2.2.1 from CRAN and with devtools master@568ac2a11 from GitHub.

I'm seeing this too (in install_dev_deps). It happens only when all the deps are already installed and install_deps has nothing to do.
