Problems with R Package Prophet

[Pidroz]

Hello Folks

I'm trying to forecast data with package "Prophet"
Installation seems good
But when i launch this line :
df <- prophet(df1)
I have this message popping :
*

Install Build Tools - Building r package from source requires installation of additional build tools
Do you want to install the additional tools now ?

If I click YES, this page open : https://www.cnet.com/how-to/install-command-line-developer-tools-in-os-x/
I really don't know what to do ...
Does somebody can help me ?
Thanks

That link is an article about how to install Xcode command line tools*, which you often need to build packages from source in R. There's another nice description in the What They Forgot to Teach You About R book (online):

Chapter 9 Set up an R dev environment | What They Forgot to Teach You About R

Summary point of that section being that the minimalist approach to take is to run:

xcode-select --install

from the shell.

* That's actually a really helpful error message, most of the time you just have to figure it out by seeing that xcrun is somewhere in your installation errors (e.g. see here).

HI @mara--I'm having similar issues. I tried running that in the shell and got

error: command line tools are already installed, use "Software Update"to install updates

When I run softwareupdate --list nothing needs updating.

If you're talking about the prophet library specifically, and you have all the tools necessary to build it, but are getting sent to a link that implies they're not there, you might want to file an issue in the package repo.

Thanks for the reply, Mara. I am encountering this issue via prophet but I don't believe this issue is specific to that package. When I run pkgbuild::has_build_tools(debug = TRUE), which is something I've seen in other threads trying to diagnose this issue, I encounter the same popup.

I was able to fix the issue. prophet uses a package called rstan. From its "Getting Started" guide there are instructions for how to install rstan from source using a Mac here. Following these instructions corrected my immediate issue, which was encountering that popup when trying to build a model using prophet, and further, pkgbuild::has_build_tools(debug = TRUE) now returns TRUE.

Great to hear!

If your question's been answered (even if by you), would you mind choosing a solution? (See FAQ below for how).

Having questions checked as resolved makes it a bit easier to navigate the site visually and see which threads still need help.

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …

I'd be happy to do so, but I'm not the original requester...think I should still do it or should OP?

[mara]

Sorry, didn't realize that. I don't think you actually can unless you're OP or an admin, so I'll go ahead and do it for you!
