Cannot start R Tools on

[wlandau]

When I start VS Code and open an R script, R Tools does not start.

The logs show this:

Stack:

• Mac OS 10.15.7
• VSCode 1.52.1
• .NET 3.1

I did have .NET 5.0.1 installed originally, but R Tools could not launch for the same reasons as above. When I downgraded to 3.1, I followed the directions here to remove 5.0.1.

Try https://github.com/MikhailArkhipov/vscode-r/releases/tag/0.0.16, it is built for .NET 5.0. I would like to make sure it runs on Mac before I publish. Thanks.

Thanks, @MikhailArkhipov. r-0.0.16.vsix seems to install and run. I am getting the warning below, but R terminals seem to start and run anyway. I cannot find any other logs.

Please check out update in https://github.com/MikhailArkhipov/vscode-r/issues/52. Thanks.

0.0.17 has been published

Thanks. Tried installing 0.0.18 and got the message "Unable to start R process. Exception: Http request to '(local)' has failed. The machine may be offline or unreachable or the network has been disconnected. Error: Web request has timed out." Not sure how this affects the extension though. I am brand new to VSCode and do not know how to program it. Probably my mistake somehow.

Try

• Open Extensions Folder command
• cd to the <R Tools extension folder>/ls in terminal
• try dotnet Microsoft.R.Host.Broker.dll - what happens?
• cd to the <R Tools extension folder>/ls/Host/Mac in terminal
• Try running 'Microsoft.R.Host' (also check if it is marked as executable) - what happens?

cd to the /ls in terminal

$ pwd
/Users/CENSORED/.vscode/extensions/mikhail-arkhipov.r-0.0.18/ls

try dotnet Microsoft.R.Host.Broker.dll - what happens?

Seems to work at first:

When I navigate a browser to http://0.0.0.0:5444, I see a blank browser session and the following in the terminal.

Try running 'Microsoft.R.Host' (also check if it is marked as executable) - what happens?
