Hi @sakshi,

We’ve seen this a couple times before, typically the Julia depot has somehow gotten into a bad state, there’ll be a fix in the next version of the Pumas VSCode extension we release. In the mean time here’s what you can try:

- go to `C:\\Users\\saksh.julia` folder in file explorer
- delete the `clones` folder
- go into the `environments` folder and delete the `Pumas@2.7.1` folder if it exists
- close and reopen vscode and try to install Pumas 2.7.1 again

Let me know if that doesn’t work for you.

do you have Pumas 2.6 installed on your system? If so, please go to Add/Remove programs and delete Pumas 2. 6

Also, please share the settings.json file (`Ctrl + Shift + P` –\> type `user settings json`)
