Angular CLI 7 New Project Fails due to CircularJSON

Question

Just reinstalled Angular CLI to version 7.1.1. When running ng new project-name, the following error occurs:

npm WARN deprecated [email protected]: CircularJSON is in maintenance only, flatted is its successor.
npm ERR! code ERR_STREAM_WRITE_AFTER_END npm ERR! write after end
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\[username]\AppData\Roaming\npm-cache\_logs\2018-12-04T20_40_23_399Z-debug.log
Package install failed, see above.

When changing into the project directory, the new Angular application cannot be served. How can this be repaired?

Answer 1

I have tried accepted answer's solution but nothing happened.

Thus after some search I found a solution for me. May be it could help someone else

npm cache clean --force

Answer 2

You should be looking at the error details.

npm WARN deprecated [email protected]: CircularJSON is in maintenance 
only, flatted is its successor.

According to it [email protected] is deprecated. You should use flatted. A super light (0.5K) and fast circular JSON parser, directly from the creator of CircularJSON. The future of CircularJSON is called flatted.

Smaller, faster, and able to produce on average a reduced output too, flatted is the new, bloatless, ESM and CJS compatible, circular JSON parser.

install it using: npm i flatted
