Using v1.5.0 seems to erase R from the PATH

[lcolladotor]

Hi,

I'm not sure if this is the best place to report this, if not, please let me know! Maybe you prefer https://git.rud.is/hrbrmstr/RSwitch/issues for example.

I'm a new hrbrmstr/RSwitch user so maybe I missed an installation step. Using RSwitch version 1.5.0 apparently is not working for me as it's no longer finding the soft link /usr/local/bin/R though which R on the terminal after I use RSwitch v1.5.0.

First, I can see that it detects the correct version of R:

On the terminal (iTerm2 but also happens in the Terminal app) I can see the soft link and R is available:

10:34 $ which R
/usr/local/bin/R
10:34 $ ls -lh /usr/local/bin/R
lrwxr-xr-x 1 root admin 47 Jul 27 09:06 /usr/local/bin/R -> /Library/Frameworks/R.framework/Resources/bin/R

If I then click on 3.6 (3.6.1) in RSwitch v1.5.0, I can see that RSwitch doesn't seem to know which R version it's point to anymore (image below) although I did get the "Success" notification with the correct version number.

I can then confirm that R is no longer found through which despite the soft link being there. Hm...

## Click on Rswitch 
10:34 $ which R
10:34 $
10:34 $ ls -lh /usr/local/bin/R
lrwxr-xr-x 1 root admin 47 Jul 27 09:06 /usr/local/bin/R -> /Library/Frameworks/R.framework/Resources/bin/R

This affects launching from RStudio for example since I get the Unable to locate R binary by scanning standard locations error message from RStudio.

If I then open RSwitch version 1.2 from mac.r-project.org/ (from the RSwitch-1.2.dmg file, so it's not in Applications and wasn't running while RSwitch v1.5.0 was) then I can change R versions again.

Thank you for your help!

Best,
Leo

Well met, Leo! Thanks for taking RSwitch for a spin. This is a fine place to report a bug and this seems to be a big one. I’m a few thousand feet in the air (heading back from DSC 2019) so I won’t be able to poke at this until tonight or tomorrow but I wanted to shoot a note to let you know I received it.

And it is definitely a bug due to a "clever" code change made after having already tested it #sigh.

Many thanks for flagging it!

Tis now fixed in 1.5.1. The Check for updates… should take you to the download page but it's also a full release: https://github.com/hrbrmstr/RSwitch/releases/tag/v1.5.1

Awesome, thanks for making this fix! I can confirm that RSwitch version 1.5.1 works for me =) Thank you again! 🙌🏽
