NativeScript CLI installation fails on linux

When I run sudo npm install -g nativescript I get this output :

Hi Kristijan Zic,

I'm currently running node 10.13, myself on Mint (which is based on Ubuntu 18.04) and have no issues with NativeScript. However there is a critical difference in what I am doing vs what your error is.

Now based on the error message; I would highly recommend you switch to use a non-snap version of Node. The problem with Snap and flatpak is they do things a bit differently than standard linux based apps to try and keep everything self contained. Which works great in most cases; however in this specific case you will probably have issues with many, many, global modules as the paths are being fiddled with by the way it packages things to keep it self contained.

This is not to say it won't ever work (or that the NativeScript team won't figure a fix for future versions of NativeScript for snap based installs), or that you can't make it work by manually creating the missing user data folders. But it is to say that it is very likely you will see many issues with other npm modules you attempt to install globally; and so right now might be the best opportunity to eliminate those future issues (and this one) just by switching to a standard node install vs the snap based one you are using.

Hi NathanaelA, thank you for answering.

I have everything else working completely without issues. And not small things either, angular and react. I would really like to have this working too. I've made a bug report to nodesource also.

For now it seems to be installing when using the --scripts-prepend-node-path but it installs with errors. I'll just see how far I can get with this but it's still an open bug that needs fixing :)

I'm glad that you haven't seen other issues. I just know based on past experience that when things start trying to control paths; it can cause other issues later. (I fought my Calibre install yesterday over this exact same type of issue; came this close to just installing it from source... 😀) I have to say; I figured Angular and TypeScript would be some of them that would cause issues in the future with node/npm. But if they are working already then maybe the issue is trivially solved. ;-)

Now as to your current issue -- Since you installed using "sudo" you will have to fix the permissions on
/home/aresminos/.npm and '/home/aresminos/.local/share/.nativescript-cli' (and all files contained inside) so that they are actually owned by you (the aresminos user) and not root. Once you fix those; it might be working properly at that point. 😀

@NathanaelA commented on Fri Feb 15 2019

I'll be honest, I'm not saying this is the best practice; (and I don't generally recommend people change their security profile; without understand ALL the possible consequences). So don't just follow random advice of strangers, even strangers who might be considered experts (or idiots). 😀

For myself after evaluating things; I personally lowered the required security for /usr/local/lib/node_modules to be writable by everyone. (not just root).

This allows me to do: npm i -g nativescript@latest as myself, and not as root which then never screws up permissions anywhere else, and it allows me to very easily upgrade nativescript (and all other global node based tools) without giving any of them root access (which in my mind is actually a far worse security issue as we (this node community in general) has had several packages in npm get compromised). So I really don't want to run any third party code as root as much as possible. 😀

Please note; this means that technically anything can install/change something in that folder; so if you are really really paranoid you could temporarily drop perms; do the npm i -g and then reset perms. But I think this security change actually improves my security footprint because I've eliminated node from running any and all third party code as root. ;-D

Have you installed NodeJS from Snapcraft?

---

@NathanaelA commented on Sun Feb 17 2019

@xlmnxp - I didn't; this (i.e. Node) is one of the few products I always install from source. ;-) But Kristijan is obviously using Snap packages as his error / paths have it in it. ;-)

@KristijanZic

Most probably you need to add the --unsafe-perm flag to the npm i command. Take a look at these issues for more details: #3694 #1364 (comment).

[KristijanZic]

Installing the nativescript with sudo privileges and using the --unsafe-permit flag seems to have installed it but I still get all the same errors when creating a project with and without using sudo.

[EDIT]: So creating the project somehow magically worked after first throwing me the errors but I have no idea how 😮

$ sudo npm install -g nativescript --unsafe-perm

At this point I try using --unsafe-perm flag with nativescript-cli command just to see what will happen:

$ tns create HelloWorld --template tns-template-blank-ng --unsafe-perm
The option 'unsafe-perm' is not supported. To see command's options, use '$ tns help create'. To see all commands use '$ tns help'.

$ sudo tns create HelloWorld --template tns-template-blank-ng --unsafe-perm
The option 'unsafe-perm' is not supported. To see command's options, use '$ tns help create'. To see all commands use '$ tns help'.

So it seems that nothing happened but then I tried tns create HelloWorld --template tns-template-blank-ng again and it magically worked 😮 Any idea what might have happened?

$ tns create HelloWorld --template tns-template-blank-ng

You can now bundle your project by passing --bundle flag to NativeScript CLI commands:
    - tns build android --bundle
    - tns build ios --bundle
    - tns run android --bundle
    - tns run ios --bundle
You can also pass the "--env.uglify" flag to use UglifyJS for minification.

Now you can navigate to your project with $ cd HelloWorld

After that you can preview it on device by executing $ tns preview

Now as to your current issue -- Since you installed using "sudo" you will have to fix the permissions on
/home/aresminos/.npm and '/home/aresminos/.local/share/.nativescript-cli' (and all files contained inside) so that they are actually owned by you (the aresminos user) and not root. Once you fix those; it might be working properly at that point.

Second your directory /home/aresminos/Projects/nativescript/ needs to also be owned/assigned to the aresminos user.

With those fixes you should be able to work fine...

The issue is fixed in CLI's rc version. You can use it by executing sudo npm i -g nativescript@rc
NOTE: The issue happens only when you use sudo for installing CLI and you do not pass --unsafe-perm, i.e.
sudo npm i -g nativescript - produces EACCESS
npm i -g nativescript - should work correctly
sudo npm i -g nativescript --unsafe-perm - should work correctly

With latest fix, all commands should work correctly.
