cargo: "error: path too long" on Windows when doing "cargo install --git"

Problem

When attempting to install a crate via git, the checkout process gets to 48% and then errors out with “error: path too long”.

Steps

Run Windows
Run cargo install --git https://github.com/web-infra-dev/rspack

Possible Solution(s)

No response

Notes

This repo probably doesn’t even work, especially since I don’t see a binary if I manually check it out and try to build it. However I’m opening this issue because it’s very reproducible and the error is generated very early on.

Hmm… I do have LongPathsEnabled set to 1, so that doesn’t appear to be the cause of the cargo failure.

You might also need to run: git config --system core.longpaths true

Cargo also needs to opt in. This can only be done via an application manifest. From my link above:

The application manifest must also include the longPathAware element.

<application xmlns="urn:schemas-microsoft-com:asm.v3">
   <windowsSettings xmlns:ws2="http://schemas.microsoft.com/SMI/2016/WindowsSettings">
       <ws2:longPathAware>true</ws2:longPathAware>
   </windowsSettings>
</application>
