bun (v1.1.17) compilation error: EINVAL: failed to move executable to result path (win10 x64)

[lukasMega]

Hello, I'm getting this error when executing bun build --compile ...

EINVAL: failed to move executable to result path

it comes probably from this line: https://github.com/oven-sh/bun/blob/main/src/StandaloneModuleGraph.zig#L525C19-L525C28

Hello!
Hello, v22.3.0!

D:\dev\buntest>

but I figured out that produced file is working, I just need to rename it manually to .exe

What I did:

• tried powershell instead of cmd
• tried to run cmd as admin
• tried different form of output name:

Any ideas how to prevent such error? I'm not sure if this happens only on my pc or it's general issue?

Solution (❗ Workaround❗ ):

Steps after bun build --compile ...

• make sure produced file like .17dd6fd66b5f86f7-00000000.bun-build is created (with size 104 MB in my case for hello-world)
• rename that file to something.exe
• now, you should be able to successfully execute that .exe file.

now, finally I have found out

Solution:

_{DO NOT USE Windows AND} D:\ _{path - move your work somewhere under} C:\ _{and this error will stop}
