sudo npm install -g @angular/cli@latest

The log given by the failure.

The following repeats itself forever:

gyp verb command install [ '8.4.0' ]
gyp verb install input version string "8.4.0"
gyp verb install installing version: 8.4.0
gyp verb install --ensure was passed, so won't reinstall if already installed

Desired functionality.

Install to be working

Mention any other details that might be useful.

1.3.2 was working.
I am on Ubuntu E2 on AWS.

Now it works, finishing to install with saying:

 + @angular/cli@1.4.1
 added 114 packages and updated 1 package in 11.718s

But if I do ng --version I get

@angular/cli: 1.3.2
node: 8.4.0
os: linux x64

I am still having this trouble.
The same way you've decribed.

@AmitMY : how did you solve it? Did you just wait?

@AmitMY the version of the CLI reported may be from the local project, not your global version.

Unfortunately there's not a whole lot we can do regarding failing or long-running npm installs. You could try reaching out to the npm team.

Had the same issue installing globally. But when I asked for the version with ng --version it ran, and told me it wasn't installed in my local project. So I installed it locally, and that ran fine.

i had the same issue in my Fedora 26. It runs a inifinite loop while installing angular.cli. It says doesn't have permission in node-sass . So wat i did was tried once more the npm install -g and then removed the node_modules from /usr/lib/node_modules/@angular/cli/ and run npm install .

This time the node-gyp bin downloaded successfully and run perfectily. Its some kind of isse with node-sass . The Error is ensuring nodedir is created /usr/lib/node_modules/@angular/cli/node_modules/node-sass/.node-gyp/8.7.0 gyp WARN EACCES user "root" does not have permission to access the dev dir "/usr/lib/node_modules/@angular/cli/node_modules/node-sass/.node-gyp/8.7.0" gyp WARN EACCES attempting to reinstall using temporary dev dir "/usr/lib/node_modules/@angular/cli/node_modules/node-sass/.node-gyp" gyp verb tmpdir == cwd automatically will remove dev files after to save disk space

I have this same issue on the newest version of Node. I was able to install after switching from version 8.7.0 to the latest stable version 6.11.4.

Same issue on my Mac. After a few hours of digging, I found that right before the loop starts it can't find python 2 on my system. After installing python with "brew install python", I was able to install angular/cli.

Seems like the real issue is that the angular/cli install depends on python 2, doesn't bother to check to see if you have it installed, and continues on blissfully into eternity without it.

Further to @rjenks comment, I ran into the same problem on my Mac, but I am using MacPorts instead of HomeBrew. The python2 symlink was already there but not in root's PATH. For an unknown reason, running npm with sudo didn't work, so I had to sudo to root. The fix for me was:

sudo su -
PATH=/opt/local/bin:/opt/local/sbin:$PATH
npm install -g @angular/cli@<version>

[polyglotinc]

So, what do we have to do about this?? I don't explicitly use Python on my Mac, so therefore have never explicitly installed it....seems like that's what npm, et al, is supposed to do!
I too am getting the loop of death trying to upgrade from angular cli 1.2 to latest.

Try adding the -unsafe-perm switch. I can’t remember whether it’s one hyphen or two. It really needs to be officially documented.

These are the workarounds I used to install angular-cli:

2. add -unsafe-perm -> thx to @CitizenTim
