Hi there,
My computer got crashed last night and I forced to reboot it. After that, I could not load rstan and get the following error. Tried to uninstall it and reinstall, but still the same error.
Error: package or namespace load failed for ‘rstan’:
.onLoad failed in loadNamespace() for ‘processx’, details:
call: NULL
error: package ‘ps’ does not have a namespace
If your question relates to installation please provide the following information:
- Operating System
Windows 10 Pro - RStan Version
latest one - Output of
writeLines(readLines(file.path(Sys.getenv("HOME"), ".R/Makevars")))
Error in file(con, “r”) : cannot open the connection
In addition: Warning message:
In file(con, “r”) :
cannot open file ‘C:\Users\ZC\Documents/.R/Makevars’: No such file or directory - Output of
devtools::session_info("rstan")
Error: .onLoad failed in loadNamespace() for ‘processx’, details:

error: package ‘ps’ does not have a namespace
