Can not install angular-cli on Ubuntu 18.04

[meightythree]

🐞 Bug report

Command (mark with an x)

I guess it affects "all" because I couldn't even install the cli.

- [ ] new
- [ ] build
- [ ] serve
- [ ] test
- [ ] e2e
- [ ] generate
- [ ] add
- [ ] update
- [ ] lint
- [ ] xi18n
- [ ] run
- [ ] config
- [ ] help
- [ ] version
- [ ] doc

Is this a regression?

It isntalls with 7.x version

Yes, the previous version in which this bug was not present was: ....

Description

Using the angular cli installation command: sudo npm install -g @angular/cli

I get this error: https://pastebin.com/aqDXNBM0

There's no such file '/home/user/.angular-config.json', I have tried creating it by the 'touch' command, but it gave another error: https://pastebin.com/xZNQUwAa

I have tried 'npm cache clean --force' command with the same results.

I tried to install a previous verison of Angular with the 'sudo npm install -g @angular/[email protected]' and it installed it however it throws "Workspace needs to be loaded before it is used.", I guess it's because of the angular-config.json I've created...

A clear and concise description of the problem...

🔬 Minimal Reproduction

sudo npm i -g @angular/cli

I have linked the errors above.

It seems that you don't have write permissions on that path.

[meightythree]

Thanks for the response!
But how come I could install a previous version of the cli?

[alan-agius4]

Because this logic is part of version 8.

That said, we should probably handle it more gracefully and not bail out when the CLI doesn't have permission to write a global config.

//cc @clydin, thoughts?

[filipesilva]

It's worth mentioning that you should not install global npm modules with sudo. Please have a look at the fixing npm permissions page.

[meightythree]

Thank you @filipesilva, I think I will check out npx.

[mgechev]

Instead of failing can we throw a warning and fallback to default config (analytics off).

Alternatively, brew handles this really well by giving you a hint about what command you should run to fix your permissions.

Not being able to write to your own home directory typically signifies a system-wide configuration issue.

Note, however, that the next patch release of the Angular CLI will not crash in this situation.

then any alternate way to fix this issue as of now

[ankitmaurya001]

I am also facing the same issue. Any way to fix this?

[frkntony]

Well, I kinda hate npm tbh. However, I was installing my tools via it for a long time. That has changed.

My solution is to use yarn:
sudo npm uninstall -g @angular/cli
sudo yarn global add @angular/cli

Works like a charm.
