[gaborcsardi]

You need a C++ compiler to install roxygen2 from source. Seems like you are on Windows, so you would need to install Rtools40 from https://cran.r-project.org/bin/windows/Rtools/

CRAN will have a roxygen2 7.1.1 binary in a couple of days, so you could also just wait for that.

Or you can install the 7.1.0 binary if you don't need the bug fixes in 7.1.1.

[JiaxiangBU]

@gaborcsardi thanks for your reply. I install Rtools 4.0 already but cannot install roxygen2 still with different error.

means that roxygen2 is loaded in this or another R session. You need to quit your other sessions, and install roxygen2 in a new session, before loading any packages.

@gaborcsardi Thanks. But I get the same error. I open only one R session inside a RStudio windows.

I open only one R session inside a RStudio windows.

Then you have a frozen session that you cannot see. Start task manager, and eliminate all RStudio and Rterm, etc. apps and processes.

[JiaxiangBU]

Start task manager, and eliminate all RStudio and Rterm, etc. apps and processes.

Yes, I am sure only one R session I open. I will restart my machine and try again. @gaborcsardi

[JiaxiangBU]

@gaborcsardi I restart my machine and open the rstudio once and run install.packages but get the same error.

Right, it is actually the Rcpp.dll. You probably have a broken Rcpp package. Reinstall Rcpp first, then install roxygen2.

[JiaxiangBU]

You are right. I cannot reinstall Rcpp successfully, I will open an issue for Rcpp first.

[JiaxiangBU]

I use the latest version of R to 4.0.2, and successfully install Rcpp and roxygen2, thanks for your help a lot to locate the problem.

[JiaxiangBU]

And from https://github.com/RcppCore/Rcpp/issues/1095#issuecomment-651045475, the @eddelbuettel suggestion, the error does not result from Rcpp but other dependencies of roxygen.

[gaborcsardi]

IDK, this does seem to come from Rcpp:

Unable to load shared target object ‘C:/Program Files/R/R-4.0.0/library/Rcpp/libs/x64/Rcpp.dll’::
  LoadLibrary failure: The specified program cannot be found.
In addition: Warning message:
The program package ‘Rcpp’ was built with R version 4.0.2

Can you load Rcpp?

[gaborcsardi]

Ah, you already fixed the issue, never mind then. Yeah, so you had a broken Rcpp installation, and re-installing Rcpp fixed the issue.

[eddelbuettel]

Yeah, so you had a broken Rcpp installation

Come on now. Please suggest a change, any change, Rcpp could or should make here.

Broken file-locking on Windows is not something we have control over.

@gaborcsardi Yes, I can load Rcpp and roxygen both when I install R 4.0.2 and Rtools 4.
This message also makes me confused. I think it just gives a warning not an error: ‘Rcpp’ was built with R version 4.0.2.

Ah, you already fixed the issue, never mind then. Yeah, so you had a broken Rcpp installation, and re-installing Rcpp fixed the issue.

Yes, based on the new R version hah, 4.0.2. Under R 4.0.0, the error happens still.

[gaborcsardi]

@eddelbuettel I am not sure what you mean. A broken installation means that the package on the disk is in a state that cannot be loaded. Historically this is usually a result of https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17478 but there are plenty of other ways, e.g. an interrupted or crashed installation. This happens to all packages with compiled code, on Windows. There is little that you or anyone else but R core can do about it.

@JiaxiangBU Can you try loading Rcpp in R 4.0.0 then? I.e. just type library(Rcpp). If that fails, then just reinstall Rcpp, and then reinstall roxygen.

[eddelbuettel]

I appreciate the more explicit language. It is, essentially, a known Windows defect. Pointing at by-stander packages serves no-one.

We both recommended to OP to reinstall, which is the only recourse. Moreover, for packages with such long dependency tails as this, there is little else to do than bisection and trying subsets of the dependency graph.

Or reading the error message. :)

[JiaxiangBU]

Under the R 4.0.0, I cannot load Rcpp, even though I can use command install.packages for Rcpp without error message.

I test this error a lot. I restart the windows machine, open a terminal to open only one session to test. But I still cannot load Rcpp. 

I take the suggestion for @ShotaOchi from https://github.com/RcppCore/Rcpp/issues/1095#issuecomment-650955884 to upgrade R yo 4.0.2.  Then I can load Rcpp.

Do you mean the warning message? ;-)

[gaborcsardi]

@eddelbuettel No, this is an error message:

Unable to load shared target object ‘C:/Program Files/R/R-4.0.0/library/Rcpp/libs/x64/Rcpp.dll’::
  LoadLibrary failure: The specified program cannot be found.

@JiaxiangBU Right, I understand now. This is not a broken installation, but something else. I can reproduce this as well on R 4.0.0. Apparently, the Rcpp binary served by CRAN does not work on R 4.0.0.

If you install from source, that seems to fix it:

install.packages("Rcpp", type = "source")

Anyway, very clearly, this is not a roxygen2 issue.

[eddelbuettel]

Or, as has been said repeatedly, upgrade to R 4.0.2.

[gaborcsardi]

This is a base R ABI change, probably unintended: https://www.mail-archive.com/[email protected]/msg42398.html

Rockstar level debugging by you and @jeroen; I just said thanks to you via DM when I saw your r-devel post (before I saw this).
