[Modular CLI] install modular command tool without require root permissions

shanguanma commented 2 weeks ago

Issue description

Currently modular is the only tool to install mojo and MAX, but it requires root privileges, which greatly limits those users who do not have privileges, such as ordinary users on computing clusters. I don't quite understand why an installation tool must obtain root privileges. And currently only the window WSL2 linux subsystem is supported in the Windows environment, why is there no support for WSL1 subsystem. I don't know if there are plans to improve it in the future.

Steps to reproduce

Include relevant code snippet that did not work as expected.
If applicable, add screenshots to help explain the problem.

$ curl -s https://get.modular.com | sh -
It looks like you are using WSL1 which is unsupported by Modular.
We recommend switching your Linux distribution to run with WSL2 instead.
See https://learn.microsoft.com/en-us/windows/wsl/install#upgrade-version-from-wsl-1-to-wsl-2 to learn how to switch to WSL2.

Version Info

- Provide Modular CLI version by pasting the output of `modular -v`
- What OS did you install modular CLI on ?

There were some issues with WSL1, for example when downloading mojo packages it often just got stuck, so chances are high even if the check wouldn't be there, you still wouldn't be able to install / run mojo.

However,the modular(i.e.: modular 0.2.2 (95d42445)) can be installed successfully, although there will be the following complaints every time it is run.

$ modular -v

and

I think I saw a fix for that somewhere... Does the ~/.modular/crashdb folder exist? If not, you might need to create it, for some version it fixed it, and for newer it doesn't, but maybe you can give it a try.

I don't know the exact errors that WSL1 brings with it, but if you could install modular 0.2.2 I guess, you're just lucky 😉
