Everytime i try to create a new project with ng new, I'm getting the message

Installing packages...npm WARN deprecated [email protected]: request has been deprecated, see https://github.com/request/request/issues/3142 npm ERR! Unexpected end of JSON input while parsing near '...pm-signature":"-----B' npm ERR! A complete log of this run can be found in: npm ERR!

I have tried re-installing angular and even node but issue still remains

My OS version is Win 10 v.1909 build 18363.592. Can someone help me with this?

Answer 1

First ,verify your NPM cached memory

npm cache verify

then try :

npm cache clean --force
npm install –g @angular/cli@latest 
ng new <YourProjectName>

If the problem persists, then try the following

npm cache clean --force
npm update
ng new <YourProjectName>

NOTE

As @0210vidit said in the comment below:

do not use dash(-) or (.) in naming

Answer 2

Try to clean the npm cache using:

npm cache clean --force

then should it works now,

ng new my-app

Answer 3

I had similar issue and installing yarn or clearing cache didn't help. I removed '-' from my app name and it worked

Error :

ng new first-app

Solved:

ng new firstapp

Hope it helps.

Answer 4

This issue is reported for angular 9 and multiple geo-locations are facing this problem. refer https://github.com/angular/angular-cli/issues/16944

to proceed you can bring you angular version to 8 with below steps

ng --version

npm uninstall -g @angular/cli

npm cache clean --force

npm install -g @angular/[email protected]

ng --version

Answer 5

I had this issue since yesterday, tried all of this and it did not work. Then I installed yarn, and configured angular cli to use yarn as the packagemanager by running this command ng config -g cli.packageManager yarn, and it worked.

Answer 6

First try the following

npm cache clean --force
npm install -g @angular/cli
ng new <project-name>

If the problem persists, then try this (this eventually solved my workflow issue)

npm cache clean --force
npm update
ng new <project-name>

Thanks!

Answer 7

In my case i've tried everything with npm and no way out.

But with yarn worked with no worries!

I'm a windows user but you can find how to install in other OS in yarn website!

1st - i downloaded yarn from his website yarn

2nd - installed the global package with vs terminal: yarn global add @angular/cli

3rd - still in vs terminal set: ng config -g cli.packageManager yarn

4th - i created my app: ng new myapp

5th - so you know te rest ...

Worked fine to me!

Answer 8

I removed my previous solution as I somehow got hung up on the uninstalled node_modules part and presented a solution that probably wouldn't have been relevant. Here is an alternate solution that might work for you...

Open a new terminal and run node -v and then npm -v to make sure you are running compatible versions: "Node 8.9 or higher, together with NPM 5.5.1 or higher" Uninstall your current Global Angular cli npm uninstall -g @angular/cli Run npm cache verify Re-Install Angular CLI npm install -g @angular/cli@latest Close your terminal window (just because). Open a new terminal window, browse to where you want your new project and try the 'ng new` command again.

Answer 9

This work fine top of all solutions and worked for me on Windows 10... Go to vs code new terminal type the following in order

1. npm install --global yarn
2. yarn global add @angular/cli
3. ng config -g cli.packageManager yarn
4. ng new projectname

this will fix the issue..

Answer 10

1. npm uninstall -g @angular/cli
2. npm cache clean --force
3. npm install -g @angular/cli

then should it works now,

ng new my-app

Answer 11

I got it working, first I installed angular 8 then ran npm install -g @angular/cli@latest. It updated to angular 9 and now i'm able to create new projects. Thank you all for your consideration

Answer 12

Angular 9 ng new myapp gives error The Schematic workflow failed......

Firstly, uninstall Angular: npm uninstall -g @angular/cli

After uninstall, you should do clean Angular cache: npm cache clean --force

After this, you should do re-install Angular globally: npm install -g @angular/cli

And check the version: ng --version

Now you can create your app: ng new your-app

Answer 13

Only solution worked for me

1. Clear NPM cache + uninstall node

2. Install Node.js

3. Install Angular CLI

This will cost you some Internet data, but better option than wandering around for nothing! Keep a back up of Node.js. Useful next time.

Answer 14

Here is the simple way, i am sure it will help because this is the error with package installation failed.

Skip node packages for now and use this command to create new app.

ng new YourAppName --skip-install

after that just go into your project directory and run npm install it will install all required packages for you.

Answer 15

I struggled with this type of issue for a while.

Adding the following environment variable to your user account should solve the issue, adding a temporary cache option.

• name: npm_config_cache
• value: /tmp/empty-cache

More information concerning npm-config .

Answer 16

Always update to the latest LTS version of Nodejs before using angular cli current version.
