access denied errors when building locally

Trying to build on Ubuntu 22.04, dotnet 6.0, I get the error below (access denied):

Installing azurite (global)

if I launch pwsh with sudo I get a different access denied error:

Any idea how to fix this?

Thanks for reporting! I haven't tried developing SharpLab on Linux yet, so I can't say I am up to date on the issues. There are definitely some parts that will not work on Linux, for example the Run mode.

Most other parts should work, but need some polish. For that Playwright error, try tweaking the browser path as per https://github.com/microsoft/playwright/issues/5592#issuecomment-827794434 -- I'll need to double-check if I need local Playwright at all.

I'll take a look, but can't promise any specific timeline at the moment.

Hey

Just adding some context , my goal is to try to add support to specify C# language version.

Some potential ways (without thinking to much):

1. Add it to the list of platforms / Roslyn branches, i.e, have another entry like C# Language Version and underneath, the versions from 1.0 -> Latest
2. Get the language version through a get parameter (www.sharplab.io?langVersion=11 for instance)
3. Add another drop down with the supported language versions

Most likely I'll make a POC based on 2 (I guess this is the easiest one) and if it proves viable we can decide if one of the other options would be a better alternative.

There are definitely some parts that will not work on Linux, for example the Run mode. Interesting. That's okeyish. Out of curiosity, why do you think it will not work on Linux? Some dependent library that only support Windows?

I'll take a look, but can't promise any specific timeline at the moment. np at all.

Getting back is already very respectful from you :)

When I find some time I'll try to follow the suggestions from MS.
