Eu estou tentando executar um aplicativo Heroku multipack que usa Python e R. Eu tenho o multi buildpack instalando R primeiro, mas a instalação do RPy não é capaz de encontrar R apesar de minhas modificações para $ PATH. O que está acontecendo aqui? R vê RHOME como "/ app / vendor / R / lib64 / R" quando o init.r é executado.
