Hello! I've been trying to install quantstrat for some time now. I have a consistent error code 127. I've tried installing with: remotes::install_github("braverock/quantstrat")

remotes::install_github("braverock/blotter") remotes::install_github("braverock/quantstrat")

devtools::install_github("braverock/blotter") devtools::install_github("braverock/quantstrat")

but the traceback is always the same. Downloading GitHub repo braverock/blotter@master sh: /usr/local/bin/gtar: No such file or directory sh: /usr/local/bin/gtar: No such file or directory Error: Failed to install 'blotter' from GitHub: error in running command In addition: Warning messages: 1: In system(cmd) : error in running command 2: In utils::untar(tarfile, ...) : ‘/usr/local/bin/gtar -xf '/var/folders/3f/yyvy83n55tv66fdw10cbb4d80000gn/T//RtmptIZ8l6/file2d0946b333f.tar.gz' -C '/var/folders/3f/yyvy83n55tv66fdw10cbb4d80000gn/T//RtmptIZ8l6/remotes2d0919f16f5d'’ returned error code 127

what could be the source of this?? Thanks in advance!

A quick search of the error code suggests remotes::install_github() can't find an untar function on your system. I don't know why that would be the case, and I don't have time to debug. I'm going to close this issue, because the source of the error isn't in quantstrat.

Ok, thanks for your time anyways Josh!

I've managed to solve it using: Sys.setenv(TAR = '/usr/bin/tar')

Hope this helps other users. I think it is a problem only for MAC users.
