I installed globally as told here https://code.visualstudio.com/docs/typescript/typescript-compiling
npm install -g typescript
both inside vscode and outside, though it installed, tsc --version doesn't work : tsc is not recognized.
I have no problem outside Windows Sandbox https://learn.microsoft.com/en-us/windows/security/threat-protection/windows-sandbox/windows-sandbox-overview
So is there a fix in this context ?
