Angular2 cli hangs while creating a new app

Question

I am trying to create a new Angular2 app using

ng new myAppName

This hangs on the line

/ Installing packages for tooling via npm   

Its been sitting there for about an hour.

The previous time this happend I killed the process and tried re-running

ng new xxx

That failed because angular cli had some reference to the app name somewhere and thats whay I had to choose a new app name.

How do I get around this?

Solution 1

I was having the same issue. I resolved by using yarn. Follow below steps

1. Install yarn through npm using the below command

   npm install yarn --global

2. Create your application using ng new but skip installing packages using the below command. You can install them manually using yarn

   ng new project-name --skip-install

3. cd project-name

4. yarn install This will install your dependencies super-fast

Solution 2

Try to run cmd as Administrator, it will take 4 to 5 minutes.

Solution 3

To fix this issue run

ng new myAppName --skip-install

then in command line go to the new project folder

cd myAppName

then run

npm install

This fixed the problem for me.

The second way is to just press Ctrl + C at the time it hangs on

 Installing packages for tooling via npm

and the go to the project folder and run npm install

Solution 4

Try npm cache clean

If angular cli already installed, run ng new command

ng new xxx

Hope this helps.

Thanks, Jasmin

Solution 5

Some people install angular-cli using root user (sudo) because on some systems using a regular user will cause a permission error. But his may cause further problems like the one you are facing.

To fix it:

1) Remove your global angular-cli (using sudo):

sudo npm uninstall -g angular-cli

2) Follow the instructions on page below to fix npm permissions:

https://docs.npmjs.com/getting-started/fixing-npm-permissions

3) Reinstall angular-cli, this time not using sudo:

npm install -g angular-cli

I was trying to install Angular on an external flash drive which I believe was part of my problem. Siva Sankar's method Yarn worked for me, although I also had to move my Angular app directory to my laptop's HDD.

I was having the exact same problem and this fixed my issue.

@Siva Sankar Rajendran I am getting error when I give yarn install as follows error An unexpected error occurred: "registry.yarnpkg.com/@angular%2fplatform-browser: unable to get local issuer certificate". info If you think this is a bug, please open a bug report with the information provided in "D:\\learn\\my-cli-app\\yarn-error.log". info Visit yarnpkg.com/en/docs/cli/install for documentation about this command.

Worked for me. It literally took minutes.

How long did yours install?

At most 5 minutes.

this worked for myself after many hours fighting with npm. Note - I did have to run the following to gert around the certificate issue mentioned above: yarn config set "strict-ssl" false -g
