The Latest Package Cannot Open

[obinnaonwuchekwa]

My MAC tells me it cannot open the package as it is unable to scan it for malicious software. It says the package needs to be updated.

Hello, I just ran into the same issue. I am in MACOS Catalina. Any ideas? I am trying to install a package from GitHub using either devtools or remote within R Studio. I hadn't tried that after I upgraded to Catalina some weeks ago. Before I didn't have any problems.

I read that the solution was to use your package and I'm really hoping to use it. Here the screen: There is no "Open / Cancel" option, just the "OK"

Right click, select open from the context menu, and then you should be able to install.

Thanks! I'll try a bit later today. Just confirming, this is not R-version dependent, correct? Im in R 3.5.3, thinking in going soon to 4, but haven't upgraded R yet. Will this identify my R version and correct accordingly? Or do I need to upgrade R to 4, before I use this tool?

Thanks very much for your fast replies:)

The latest version is keyed to R 4.0.0. Due to how frequently R changes the toolchain and the different kind of macOS operating systems, it's easier to freeze a version at each version. If you're just getting into compiled code, you probably want to use R 4.0.0.

This installer mainly attempts to automate:

If you hold the control button on your keyboard when left-clicking the .pkg installer, it should let you proceed with the toolchain installer.

Hi, I got it opened! But the installation failed. I am on macOS Big Sur 11.0.1. I took a screen shot:

Now a year later, Exactly same failure behavior as "paprika920 commented on Nov 26, 2020". macos-rtools-4.0.0.pkg fails with the above msg "The Installation Failed." R version 4.1.1. Mac OS Big Sur 11.5.2

Can we install toolchain needed for rstan in Mac OS Big Sur? Thx

Same issue: installer macos-rtools-4.0.0.pkg fails with MacOS Monteray 12.0.1 (as of Feb 2022) Correction planned? Workaround?

The same issue here with MacOS Monterey 12.1.

Looks like I'm joining the club of "The Installation Failed." I have R version 4.1.1, Mac OS Big Sur 11.4. Me error message looks like the one from @paprika920. I'll keep looking for workarounds and report back if I find something!

edit: I updated to Monterey 12.0.1 an am still receiving the same error message.

[mattysimonson]

Same "The installation failed" message here with Mac OS Monterrey 12.2.1

[daaronr]

Same message, also with Mac OS Monterrey 12.2.1

[xorange]

Same on Monterrey 12.5, with release 4.0.0

Also I'm suggesting using the 👍ThumbUp icon (in Top-Right button in each comment) to report on the same issue, so that every one in thread would not get a notification spam each time a similar response came up.

After a quick scan, It seemed that the macos pkg only contains a shell script.

git clone this repo and run sh scripts/postinstall should have the same effect as installing the pkg.

My Environment:

Same on Monterrey 12.5, with release 4.0.0

reported that gfortran version is not found, therefore the failure.

I think for whomever failed to install, just goto gfortran-for-macOS's release page and find one suitable for you Mac, and You(We) are good to go.

Update:

I've succeeded with cmdstanr::install_cmdstan() in R Studio, which calls clang to compile some cpp file. So I'm guessing (new to R, all I could do now is guessing) "C++ toolchain in R" is just xcode environment. And my environment is good to go.

• hint: If you could build C++ with CMake on your Mac, you're probably good to go
• hint: Download a proper gfortran-for-macOS's release
• Feel free to correct me if I'm wrong. And DO correct me if so.

Referring to: https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos/

I'm gaining confidence that my instructions are correct.

If you have no idea for what "toolchain", "CMake", "environment" means, just follow these steps:

Open the Terminal from /Applications/Utilities/ Type the following into Terminal

xcode-select --install Press “Install”

Verify installation by typing into terminal: gcc --version

This installer has been superceded by the {macrtools} R package, which automatically installs and configures the R toolchain for compiled code on macOS.

Please do not use this installer package as it is notably out of date.
