I want to install "qdap" package to run a text mining project. I tried installing the package in many different ways: 1. intsall.packages("qdap") 2. Downloading the file locally then installing 3. Using devtools

library(devtools)
install_github("trinker/qdapDictionaries")
install_github("trinker/qdapRegex")
install_github("trinker/qdapTools")
install_github("trinker/qdap")

I always had the same problem. It seems to be related to rJava package. I tried to install rJava but I wasn't successful.

I'm more of a data analyst than a developer so I don't have much experience with development (using terminal commands or fixing java on my mac).

I'd really like to use this "qdap" package. Could you please help me figure out in a simple manner?

Here's the error message after I install the package:

Maybe the key is in the following 

Unable to find any JVMs matching version "(null)".
No Java runtime present, try --request to install.

and

Warning in system("/usr/libexec/java_home", intern = TRUE) :
  running command '/usr/libexec/java_home' had status 1

Are you sure you have installed a JVM? And if yes, the correct one? Because it seems to not find it.

You can download JVM from here.

I hope this helps!

  • I managed to install java 8 on my mac but that didn't change anything. Still stuck :( – Mohamad Yassin May 17 '20 at 22:40
  • Did you check the location of the installation? Did you get the same error? – MacOS May 18 '20 at 08:02
  • I'm not very fluent when it comes to java and mac development. But after reading and asking around I came to realize that this is a problem with java + macOS configuration that can only be fixed by accessing dev tools (XTools). Which is a deep rabbit hole. Apparently the "qdap" package isn't suitable for mac users unfortunately. – Mohamad Yassin May 18 '20 at 23:02
  • I see. Maybe this [link](https://www.r-project.org/nosvn/pandoc/qdap.html) helps you out! Also, XTools is insalled these days when you install XCode from the AppStore. Did You install it yet? – MacOS May 19 '20 at 06:24
  • Thanks for sharing the link. I already looked at it and tried all possible angles. It is a java thing and I feel like it would be a deep dive that will sidetrack me from my objective: building a text mining repo. I decided that the best solution is a workaround by using base regex function instead – Mohamad Yassin May 19 '20 at 23:16
  • I asked around and it seems like other people found it difficult to run this package on macOS – Mohamad Yassin May 19 '20 at 23:17
