maturin develop failed on Windows because of utf-8 encoding error

[bachue]

Bug Description

I'm developing a PyO3 project. Actually this project works well on Linux / Mac, but failed on Windows 10.

I have no idea which file includes invalid utf-8 character.

Your Python version (python -V)

python 3.10.4

Your pip version (pip -V)

pip 22.1.2

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

Run these commands on Powershell

git clone git@github.com:bachue/rust-sdk-python-bindings.git
cd rust-sdk-python-bindings
.\.env\Scripts\Activate.ps1
.\.env\Scripts\python.exe -m pip install pip --upgrade
.\.env\Scripts\python.exe -m pip install ".[tests]"
maturin.exe develop

Then failed just like the snapshot.

I think the error may caused by one of the following lines

maturin/src/develop.rs

Line 94 in bc15baf

str::from_utf8(&output.stdout)?.trim(),

maturin/src/develop.rs

Line 95 in bc15baf

str::from_utf8(&output.stderr)?.trim(),

maturin/src/develop.rs

Line 102 in bc15baf

str::from_utf8(&output.stderr)?.trim(),

Could you debug it? I don't have a reproducible Windows environment.

Ok, I got the reason now, running PowerShell with Administrator could resolve it.

Reopening because we should provide a better error message.
