"fvm use" doesn't work

[rayliverified]

@leoafarias Thanks for taking a look! I've followed the steps in the ReadMe and am running into this issue.

I guess I still don't fully understand how to reference a version "per project". Is this done manually via a config file or through fvm?

[Giuliano-Stravini]

@leoafarias Not solved, but the log changed!

PS C:\projetos\vimob\vimobpoc\app> fvm list
1.10.14
1.9.1
beta
dev
PS C:\projetos\vimob\vimobpoc\app> fvm use 1.10.14
Activating 1.10.14...
⚠️  Sorry could not link C:\fvm\1.10.14\bin\flutter
PS C:\projetos\vimob\vimobpoc\app>

I already have flutter 1.10.15(dev) installed, this can be a problem?

It's been decades since I've used Windows, but see if this applies: https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/create-symbolic-links

@Giuliano-Stravini thanks, I am still working through some of the kinks. I was able to replicate the issue when doing the use command on a directory that does not have fvm installed. For some reason, it doesn't fall under the same error logging logic that exists right now.

I see you are running within the app, so I will do further investigation.

[leoafarias]

@Giuliano-Stravini Please run version 0.6.6. I just made some updates. I am not sure this will fix your issue however you should get a bit better logs once you get the issue. Do you mind sending it here?

[leoafarias]

@Giuliano-Stravini can you run with the --verbose flag, and also have you made any changes to the config?

[Giuliano-Stravini]

@leoafarias Yes, i configured the cache path

I was able to replicate the issue of saving in my Home directory which on the Windows would be C:/ . That would cause the issue.

If you trying to store on C I believe you can just remove the cache url. I will probably add better validation for this case and will update soon

[Giuliano-Stravini]

Oh i got it.

This happens in any path config. I guess i did something wrong haha

Thanks @leoafarias for investigating these issues. I can't wait for FVM to work as it will save me so much time.

Currently, I'm experiencing the same issue as above.

My fvm is installed in C:\Users\Laptop\fvm\versions\master\bin\flutter and not in the local project folder. From #21, I see that one way for fvm to work from inside the project? How can I set it up to work that way?

Thanks :)

[leoafarias]

@searchy2 I think these are separate issues. The way FVM works is that you can install versions and they are cached globally. When you install the version local it references that global version.

This is important to avoid the long build processes that can happen with flutter.

Let me know if that clarifies

[rayliverified]

@leoafarias I'm sorry that I don't fully understand and need some additional clarification.
How do you install FVM locally? Right now, I've ran pub global activate fvm. Do I need to install it in my project folder somehow?

Thanks 🥇

[leoafarias]

@searchy2 sorry for the delay responding. The SDK versions are installed "globally" This is important because if you have multiple projects using the same version it reuses instead of having them multiple times. As you probably know they get pretty large.

So the versions are "cached" globally, but they get referenced per project. So a project can reference any of the globally cached versions.

You should be able to install and do everything you need based on the instructions on the readme file. Please let me know if there is anything that is not clear so I can clean up.

AFAIK, fvm will create a symlink (or its equivalent) in the directory you ran fvm use. Not sure how it is in windows, but in linux i typically invoke fvm (after fvm use) via the following ./fmv <command>. Note the ./ to implicitly invoke the fvm file in the current directory.

[leoafarias]

@searchy2 I suggest reading the instructions on the readme if you are still having issues. You will have to install the flutter version first. I will be adding a better description and maybe a prompt to install the version

[humazed]

I'm having the same issue as @searchy2

[rayliverified]

Thanks for the suggestion @leoafarias
Unfortunately, I still run into the link issue.

[leoafarias]

@searchy2 version 0.6.7 has some fixes for windows that I think it might address your issue. Would you mind testing with that version?

[kwado-tech]

To create a symlink, fvm requires administrative rights. You can open a terminal with administrative rights and cd project-root-directory and run fvm use [flutter version]
