command not found: Not supported on Mac?

[simplificate]

Hi there,

I was kicking the tires on this project and had trouble getting this (and, really, any) R-related extension working on Mac. I found this article on RTVS (from Jan 2018), which said:

RTVSis not presently supported on Visual Studio for Mac.

I know that this project is derived from RTVS, so I wondered if that was the root cause (although your extension says it supports Mac). I also tried this on two different Macs and got the same result. Here are the steps I took:

• Install R (Dec 2018)
• Install .Net Framework (not sure if I need this)
• Install vscode-r extension
• Create new file in Visual Studio Code
• Command Palette, then R: Create R Terminal

Error:

command 'r.createRTerm' not found

I found this page which suggested running an npm install in the extension folder. Here's the path where I found it:

/.vscode/extensions/mikhail-arkhipov.r-0.0.5

This didn't help. Here's a dump of what happened:

I have a tech background and have used R Studio, but I'm not an expert in either of these. I'm an analyst and I mostly use VSC for writing SQL for my day job. I also understand this is a volunteer project, so I appreciate the help!

Thanks, Ken

See #7. Waiting a bit before starting the terminal may make the problem go away.

Is startup complete as in

or the extension is still loading?

[MikhailArkhipov]

Also, you may have to save the new file with .r extension first since otherwise VS Code does not know that the file is in R.

[simplificate]

@MikhailArkhipov ah, thanks for the pointer to look in the Output for the Startup Log. Here's what it says:

> Checking for .NET Core... OK
> Installing libzip (required for the R process executable)... undefined

I'm going to try to install libzip and see if that helps.

[simplificate]

Ok, brew install libzip appeared to clear the libzip error. I quit and relaunched VSC and saw this:

R Tools Startup Log

> Checking for .NET Core... OK
> Activating R Language Server...

This time, though, the extension told me with a notification it couldn't be started. Here's a new error in the R Tools Output.

R Tools

> [Error - 5:18:45 PM] Starting client failed
> Launching server using command dotnet failed.

Going to google the second line in this log...

[simplificate]

I can run dotnet from the command line. I also installed the .Net Core 2.1 library (I already had 2.2) in case of weird incompatibility. That didn't fix the issue. Am I missing something else?

> $ dotnet --list-runtimes
> Microsoft.AspNetCore.All 2.2.1 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
> Microsoft.AspNetCore.App 2.2.1 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]
> Microsoft.NETCore.App 2.1.7 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]
> Microsoft.NETCore.App 2.2.1 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]

As a sanity check, here's R:

I saw that Issue #2 was actually cited in the changelog as having to do with libzip. Reading through it, I saw Mikhail recommend checking the Microsoft R Host. I'm not sure if this means anything, but I tried it:

> $ pwd
> /Users/kenwalke/.vscode/extensions/mikhail-arkhipov.r-0.0.5/ls/Host/Mac
> $ ./Microsoft.R.Host 
> Segmentation fault: 11

[MikhailArkhipov]

Yep, that is missing libzip. Installing libzip (required for the R process executable)... undefined means extension attempted to install libzip via brew install libzip but failed. However, lack of "Installing Homebrew (required to install libzip library)... " tells that homebrew is installed.

[simplificate]

Thank you @MikhailArkhipov. Libzip is successfully installed now, but I can’t make heads or tails of the new error:

> [Error - 5:18:45 PM] Starting client failed
> Launching server using command dotnet failed.

[MikhailArkhipov]

Do you still get > Segmentation fault: 11?

[simplificate]

@MikhailArkhipov yes, same result

vscode-insider solved the problem for mac users

Hi, I am facing the same issue. Are there any updates? I am very new to vscode but is there a way to specify the directory for the libzip library?

[hongooi73]

Unfortunately it looks like Mikhail has moved on to other projects. This was always meant to be more of a personal project anyway, not a Microsoft-supported extension.

You can try the other R extension for VSCode, which is still actively supported:

https://github.com/Ikuyadeu/vscode-R

It works very well in conjunction with the R LSP client, for tooltip help and language completion features:

Thanks for the reply.

I think that I have found a workaround for MacOS. If you start VS Code via the terminal then "R Tools" seems to work (open -a Visual\ Studio\ Code). This is a workaround I found in the "LaTeX workplace" github, and it has to do with the PATH set by the different ways of launching the app.

I get a new error (see below) but r tools seems to work in the editor itself. Maybe I am wrong.

[Error - 10:39:41 AM] Connection to server is erroring. Shutting down server.

A fatal error occurred, the folder [/usr/local/share/dotnet/host/fxr] does not contain any version-numbered child folders
