Trying to follow the Express getting started tutorial.

I generated an app and ran npm install following the provided instructions.

> npx express-generator --view=pug myapp
> npm install

New to node and I have no idea what this means. Looks to be a problem with npm and not Express?

I tried running npm cache clean --force and deleting node_modules but neither helped.

If it is relevant, npm version 7.6.3 and node version 15.11.0.

My solution was to install older version of semver and update npm itself to version 7.7.0. I used the commands:

sudo npm install -g [email protected]

and then

sudo npm install -g [email protected]

After it worked

for me just worked sudo npm install -g [email protected] ❯ node -v v15.11.0 ❯ npm -v 7.6.3Sax

After another another round of updates from the package manager, I ran into more problems (See this question).

From the question linked above I found installing node directly from the nodejs website to be a more permanent and robust solution.
