There was an error when I ran apsimonr

Hi Drew,
IT'S Wrong when I run ApsimOnR

Packrat is not installed in the local library -- attempting to bootstrap an installation...

No source tarball of packrat available locally
Using user-library packrat (0.6.0.1) to bootstrap this project
Packrat mode on. Using library in directory:

• "D:/R_package/ApsimOnR-master/packrat/lib"
  Error in loadNamespace(name) : there is no package called ‘yaml’

Hi @dxl-cde - what command did you run which produced this output?

嗨，@ dxl-cde-您运行了什么命令生成了此输出？
Hi drew
Thank you for your reply
What I'm running is ApsimOnR.Rproj , and then this error appears after opening rstudio. Does this affect the use of the package?

Worthy to try install yaml in rstudio

I haven't had a chance to look into this yet other than to check that it's not happening on my pc, but if you're only interested in using the package, you shouldn't need to open the .Rproj file. You should be able to just run:

install.packages(c('remotes', 'dplyr', 'nloptr', 'DiceDesign', 'DBI', 'cli'))
remotes::install_github('SticsRPacks/CroptimizR')
remotes::install_github('hol430/ApsimOnR')

I will have a closer look at this error when I get the chance.
