Why does the newest Angular CLI have a corrupted packages?

Question

I installed the latest Node and Angular on Windows 10

npm install npm@latest -g 
npm install -g @angular/cli@latest 

But when I try to start a project ng new new-project I get the following error

    npm WARN tarball tarball data for @angular/compiler@^6.1.0 (sha512-TY6axB1c7VvYXf+ebFDq3Ej+edgii3CDxew8HnyTFAWeDF2Gh8io1vTYwtdyDka6U53ASaheM1HpiUjzvYH0jQ==) seems to be corrupted. Trying one more time. 
    npm WARN tar ENOENT: no such file or directory, open 'C:\Users\admin\Desktop\...\node_modules\.staging\@angular\common-6be83a81\locales\si.js'
    ...

    npm ERR! A complete log of this run can be found in:
    npm ERR!     C:\Users\admin\AppData\Roaming\npm-cache\_logs\2018-10-08T01_01_48_404Z-debug.log
    Package install failed, see above.

I tried to uninstall Node.js and Angular CLI completely and then reinstall again

 npm install npm@latest -g 
 npm install -g @angular/cli@latest 

But still the same error ..... So I googled this issue. It seems like some people had it too, but then it magically disappeared for some people.

How to fix this?

Answer 1

I was getting the same below error when attempting to a create new project using ng new command.

npm WARN tarball tarball data for @angular/compiler@~7.2.0 (sha512-5yb4NcLk8GuXkYf7Dcor4XkGueYp4dgihzDmMjYDUrV0NPhubKlr+SwGtLOtzgRBWJ1I2bO0S3zwa0q0OgIPOw==) seems to be corrupted. Trying one more time.

I tried many things but what did not worked and what finally worked for me I have listed below. My working node version is 12.2.0 and npm version is 6.9.0 (i.e. latest version).

What did not worked:

1. Downgraded node js to other lower versions (tried many version)
2. Deleted package-lock.json file from project and executed npm install
3. Executed npm install --registry https://registry.cnpmjs.org instead of npm install
4. Deleted npm and npm-cache folders from AppData\Roaming and then again installed node js
5. Deleted node_modules folder, executed npm update and then executed npm install
6. Executed npm cache clean --force and then executed npm install
7. Reinstalled @angular/cli
8. Checked for any firewall / antivirus (in my case it was disabled)
9. Opened node command prompt as an administrator
10. Checked user permissions for the project folder

Finally what worked is:

Installed the component for which it was giving error. npm install -global @angular/compiler

Answer 2

I had the same problem with node 12.13.0 and npm 6.13.0

npm WARN tarball tarball data for @angular/compiler@^7.2.11 (sha512-5yb4NcLk8GuXkYf7Dcor4XkGueYp4dgihzDmMjYDUrV0NPhubKlr+SwGtLOtzgRBWJ1I2bO0S3zwa0q0OgIPOw==) seems to be corrupted. Trying one more time.

For me the problem was npm. After upgrading npm to the newest version with npm i -g npm@latest the problem vanished. So it seems to be a problem with npm itself and not the Angular/CLI.
