not able to install

[cmavian]

Hi,
I tried to install in many ways, but none looks to work. Any tips?

install.packages("skygrowth")
Warning in install.packages :
package 'skygrowth' is not available (for R version 3.5.1)

tried :

if (!requireNamespace("BiocManager", quietly = TRUE))

• install.packages("BiocManager")
  

BiocManager::install("skygrowth")
made a lot of installing but then nothing:

require(skygrowth)
Loading required package: skygrowth
Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called 'skygrowth'

tried with > remotes::install_github("mrc-ide/skygrowth")

and that did not work either.

:(

Could you please try:
devtools::install_github("mrc-ide/skygrowth")
If you don't already have the devtools package you will need to first install it using:
install.packages("devtools")

devtools installed no problem, while unfortunately skygrowth gave me this error:
Downloading GitHub repo mrc-ide/skygrowth@master
tar: Failed to set default locale
tar: Failed to set default locale
Error: Failed to install 'skygrowth' from GitHub:
Could not find tools necessary to compile a package
Call pkgbuild::check_build_tools(debug = TRUE) to diagnose the problem.

and opened this page

skygrowth contains code in C++ which needs to be compiled.
Presumably you are on a Mac and you need to install the command line developer tools.
The easiest way to do so is mentioned at the end of the page you linked to, ie open a Terminal and type the command make which will prompt installation.

yes I am on a mac :(
I will try thanks!

still having few issues, new ones now.

devtools::install_github("mrc-ide/skygrowth")
Downloading GitHub repo mrc-ide/skygrowth@master

Installing 1 packages: Rcpp

There is a binary version available but the source version is later:
binary source needs_compilation
Rcpp 1.0.4 1.0.4.6 TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel) yes
installing the source package 'Rcpp'

trying URL 'https://cran.rstudio.com/src/contrib/Rcpp_1.0.4.6.tar.gz'
Content type 'application/x-gzip' length 2751467 bytes (2.6 MB)

Error: (converted from warning) Setting LC_CTYPE failed, using "C"
Execution halted
Error: Failed to install 'skygrowth' from GitHub:

I tried also to install Rcpp independently and did not work either

any last resort?

[xavierdidelot]

So it seems you are now having issues installing Rcpp which is required by skygrowth. The easiest option is probably to install it from binary using:
install.packages("Rcpp",type = "binary")
If this succeed you can then move on to installing skygrowth.
