无法从 github 安装 Quantstrat

Question

Have followed the processes outlined on the Github repo.

Have tried installed blotter first and then quantstrat. Doesnt work

Have then moved to installing all dependencies first.

install.packages("FinancialInstrument",repos="https://github.com/braverock/FinancialInstrument")

When trying to install from Github using devtools get the following error.

devtools::install_github("braverock/blotter") Downloading GitHub repo braverock/blotter@master ✓ checking for file '/private/var/folders/_8/zy8__ntx5cx0_lnbybvfjhsr0000gp/T/Rtmp0wtY3O/remotes2547e2faf85/braverock-blotter-67be2c8/DESCRIPTION' (400ms) ─ preparing 'blotter': ✓ checking DESCRIPTION meta-information... ─ cleaning src ─ checking for LF line-endings in source and make files and shell scripts ─ checking for empty or unneeded directories ─ looking to see if a 'data/datalist' file should be added ─ building 'blotter_0.14.8.tar.gz'

I fixed the issue using Sys.setenv(R_REMOTES_NO_ERRORS_FROM_WARNINGS=TRUE) from https://github.com/r-lib/remotes/issues/434
