ERROR: dependencies ‘FeatureExtraction’, ‘PatientLevelPrediction’, ‘OhdsiSharing’ are not available for package ‘oneyearhypertension’

Issue while loading Prediction package in R Studio.
When we click on Install and Restart button.

Tried to install above package with below command and success:

command:

install.packages(“drat”)
drat::addRepo(“OHDSI”)
install.packages(‘FeatureExtraction’)

Error:

How about running the codes below first before install and restart ?

# install.packages("devtools")
library(devtools)
install_github("ohdsi/FeatureExtraction")
install_github("ohdsi/PatientLevelPrediction")
install_github("ohdsi/OhdsiSharing")

The error message suggests Java isn’t installed (or at least not the 64-bit version).

Could you try following the installation instructions for the OHDSI Methods Library in the Book of OHDSI ?

Have you installed Java and assigned the JAVA_HOME OS variable?

Once you do, it can be helpful to run R CMD javareconf to ensure everything is assigned properly.
