Yarn: Yarn 0.20.3 reports as 0.19.1 on Windows using MSI

[patoncrispy]

I thought I was having problems updating Yarn, so I uninstalled the version I had on my machine, installed the new one from the MSI but the version number seems to be incorrect via the CLI.

That is strange.
Could you run self-update at some point?
In that case the self-updated location would override it

[patoncrispy]

Command 'self-update' not found. I take it then that the installation is incorrect, or something?

[bestander]

Try uninstalling it completely.
And installing again

I did. Checked the installation directory and all gone. Wouldn't work from the command line. No installation via NPM. Re-installed via MSI and I got the result in the image attached.

Using NPM works fine.

Maybe the MSI installer leaves some traces from previous install cc @Daniel15

I've had this issue since v0.18.1. Haven't tried installing via npm to see if that fixes it

[Daniel15]

I've seen this happen when people install Yarn via Yarn itself. It usually
means there's another Yarn on your PATH. Can you try searching your
computer for "yarn.cmd" and see if one exists outside the Program Files
directory?

I did find one in the old self-update folder that apparently wasn't cleaned up on uninstall. Uninstalling, deleting that folder (well, the entire %ProgramFilesx86%/Yarn folder), and reinstalling fixed the version issue, @Daniel15.

We need to sort out this self-update feature

I guess there's code that's looking at the self-update folder that should be deleted. Removing that should fix this

[patoncrispy]

I used the MSI, not self-update, which wasn't available as a command anyway.

[Daniel15]

self-update is an old feature that doesn't exist any more (it needs to be reimplemented in a more reliable way). However, for people that have ran self-update in the past, they might still have old versions around.

[Daniel15]

2720 will fix this.

Along with deleting your Program Files (x86)\Yarn folder after uninstalling, you need to delete your Appdata\local\yarn folder as well.

To find the Appdata\local\yarn folder, type %appdata% in the run dialog box (win+R), move up a folder and move into local folder there, here you'll find the yarn folder to delete

[Daniel15]

2720 removed the self-update-related loading code. The only issue now will be if you install Yarn using Yarn or npm, which is pretty rare.
