The package should be available to install via CRAN: https://cran.r-project.org/web/packages/CausalImpact/index.html Can you try adding this package to a R code environment instead of trying to install it at runtime , as it may provide more information on the reason it's failing to install.
If that still fails, please share the code env diagnostics logs or open a support ticket if there could be any confidential information in the code env diagnostics.
