I cannot install pug using the command "npm install pug --save". I get a "RollbackFailedOptional" ...

I dont know what else to look for in the error so if you need me to upload a picture or something let me know! Im stuck until this finishes. I may just try to proceed without pug html

Please show your code.

Code

Wrap your code with 3 backticks (```) on the line before and after. If you specify the language after the first set of backticks, that'll help us with syntax highlighting.

      ```html
      <p>This is code!</p>
