I wrongly installed Deno in PowerShell without run as Administrator – Cotyledon

Answer 1

Deno did not install properly.

1. Open Powershell and Run as Administrator

2. After that, if you are using windows type this command to install properly

3 . iwr https://deno.land/x/install/install.ps1 -useb | iex

that blog doesn't contain anything about Run as Administrator – Cotyledon

Answer 2

I had the same issue. deno run index.js didnt work in VSCode terminal but deno worked in powershell. What I did? I simply closed the VSCode and opened it again. "WALLAH!" it worked!

I installed deno with 4 different methods. I installed using an administrator console. None of it seemed to be working. Closing and re-opened VS code finally worked! – Pyemia

Answer 3

It's not a matter of the state of the installation being wrong. I closed the cmd window that installed deno in and re-opened another window and the environment variables were refreshed properly with the path updated.

Running deno again worked after the cmd window was opened.

Either the process of installation is wrong or windows has a breaking change.
