Angular project in GIT. Can't develop locally

Question

There is an angular project in a GIT repo. From a vanilla system (Mac OS-X Mojave 10.14.6) I'd like to clone it, install whatever Angular components are required, and continue dev on the project but I can't seem to get a dev environment working.

npm version 6.10.2 node version 10.16.2

I clone the repo and using bash, navigate into the directory with package.json.

$npm install
$ng serve

-bash: /usr/local/bin/ng: No such file or directory

From what I understand, npm install should install whatever I need.

This is the contents of my package.json.

Answer 1

You could to use npm start instead of ng serve.

---

Why that happen?

Because on your environment there is no ng in global scope so you will get that error. You can also run npm install -g @angular/cli to make it available in global scope.

---

Why npm start works?

Inside package.json, you can see there are some commands inside script block. With that, nodejs will find the binary file in local scope (inside folder node_modules/.bin), you've ran npm install already so that ng will available in local scope.

Hope that helps!

Answer 2

You need to install the Angular cli globally.

npm install -g @angular/cli

or

npm install -g @angular/cli@7.X

Seeing you have a 7 project
