Package Loading Failed

[susiemg]

Hello, I'm trying to load the package (because I had installed it previously) in R but I get the following error:

Error: package or namespace load failed for ‘forecast’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘tseries’ In addition: Warning message: package ‘forecast’ was built under R version 4.0.5

When I tried re-installing the package or installing the tseries package myself I get this error: ERROR: compilation failed for package ‘tseries’

• removing ‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library/tseries’ Warning in install.packages : installation of package ‘tseries’ had non-zero exit status

Any help would be greatly appreciated

The problem is with tseries, not forecast.
