I need a packages witch is located on Github. And I am aware that there are multiple solutions to install the package in R.

I am trying to install the package on a Windows server. This is what I tried:

Solution 1 (which is based on the Vignette)

install.packages("devtools")
library("devtools") 
devtools::install_github("bmschmidt/wordVectors")

Error: Could not find tools necessary to compile a package
In addition: Warning messages: 
1: In strptime(xx, f, tz = tz): unable to identify current timezone 'C': 
Please set environment variable 'TZ'

I tried many things to solve this:

  1. Reinstalling Devtools, use the CRAN devtools version
  2. Reinstalling R and Rstudio (installing the latest versions as admin) (Error : Could not find build tools necessary to build)

But still the same error...

So I tried a workaround to install the packages on my computer:

Solution two

  1. Download ZIP file from (https://github.com/bmschmidt/wordVectors)
  2. Unzip the ZIP file

But the result is an error again:

 library(devtools) 
 install("path/to/unzipped/file") 
 library("wordVectors") 

Error there is no packages called wordVectors.

Anyone an idea what is going on? I struggled the whole day with this issue. Help is really appreciated! Thanks!

Edit Also Rtools is (re)installed (the latest version...)

  • Try installing [`Rtools`](https://cran.r-project.org/bin/windows/Rtools/).From [this](https://github.com/r-lib/pkgdown/issues/376#issuecomment-315757015) GitHub issue answer.. – patL Feb 18 '19 at 10:17
  • Thanks @patL, we already installed Rtools... unfortunately, without results.. – R overflow Feb 18 '19 at 10:23
  • I know it's a cliche but have you tried restarting your rstudio/machine (usually does the trick in windows)?. In addition, could you please add `sessionInfo()`? – DJV Feb 18 '19 at 10:30

    I suspect R is not seeing your Rtools. When installing Rtools, make sure to check the box for "edit the system PATH". Then restart RStudio. Then load `library(devtools)` and see what `find_rtools()` returns. It should be TRUE. – neilfws Feb 18 '19 at 10:33
  • Thanks @neilfws. Do you know where I can find the function? It is neither in the covr package. > library(devtools) > find_rtools() Error in find_rtools() : could not find function "find_rtools" – R overflow Feb 18 '19 at 10:47
  • I'm following [this guide](http://stat545.com/packages01_system-prep.html). Perhaps it's outdated. Could try `pkgbuild::has_rtools()` and `pkgbuild::rtools_path()`. – neilfws Feb 18 '19 at 10:59
