I don't think this is angular-cli specific. It is being caused by the sass package. I'm running ng n test on windows which gives a verbose error:

2701 http fetch GET 304 https://registry.npmjs.org/sass 55ms (from cache) 2702 silly fetchPackageMetaData error for sass@1.23.3 Unexpected end of JSON input while parsing near '...\ncwmoW47aRoIrxuhYgKu'

I get the same error trying to install sass in an empty node project. It looks like npm has a problem with the json returned from https://registry.npmjs.org/sass. I was on npm v 6.13.4 and updated to 6.14.2 to see if it fixed the issue but that didn't help.

ncwmoW47aRoIrxuhYgKu is part of the dist.npm-signature in the json returned from https://registry.npmjs.org/sass.

[JayChase]

npm cache clean --force
npm i -g @angular/cli

has fixed the issue for me.

Hey JayChase,

I have tried your solution but didn't helped me. I found the OS is blocking the Schematic workflow due to some permission level for my user account. Will try to reset the OS and try again as root user.

Thanks for your reply.

This issue is with the Hard Ware of my PC. Not Angular CLI issue. Thanks for the help.

[Ewaoche]

hello guys, please am having same issue -- not able to install angular/cli

[clydin]

If the package installation failed (which is done by executing the system's node package manager: npm, yarn, etc.), then you can try to run ng new my-app --skip-install to generate the application without that step. From there you can attempt to manually run the package manager (npm install/yarn/etc.) from within the new project. For assistance with any failures at that point, please direct inquiries to the package manager's project.

I'm a newbie. I'm trying to create my first angular app and I got this problem too.
the error in log file: "error Unexpected end of JSON input while parsing near '...f1rUtt/W63ltUP8dva/XP'"
latest node version, latest npm version, latest angular cli version, when "ng new myapp", I choose options: add router, cscc.
I try to "npm cache clear --force", reinstall angular cli, etc, but it doesn't work. Still got the error message:
"The Schematic workflow failed. See above."
"npm ERR! Unexpected end of JSON input while parsing near '...f1rUtt/W63ltUP8dva/XP'"
Does somebody have solution ?

Does somebody have solution ?

after clean uninstall node, npm, angular
rm -rf /usr/local/bin/npm /usr/local/lib/dtrace/node.d;
rm -rf ~/.npm;
rm -rf /usr/local/bin/node;
rm -rf /usr/local/lib/node_modules/npm/;
and install all again by homebrew (not use node installer), I don't get above error anymore
brew install node;
export NODE_PATH='/usr/local/lib/node_modules'
brew install angular-cli
but after that I get new error
"error Response timeout while trying to fetch"
Maybe I have some network error...but I can access the link by browser. I don't know why, but try again with some differences
I remove project and create again but skip install like these

1. ng new angular --skip-install
2. cd angular
3. npm i
   everything's fine. And try
   ng serve
   The angular app start successfully!
