[Python]can't find Rust compiler

[yuanhaorannnnnn]

I'm new for erdos, and I'm using README for installation and demo,
I've already done this
rustup default nightly # use nightly Rust toolchain
git clone https://github.com/erdos-project/erdos.git && cd erdos
and simple works fine,
python3 python/examples/simple_pipeline.py
But I'm stuck at
python3 python/setup.py develop
the error info is

running develop

error: can't find Rust compiler

If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

To update pip, run:

pip install --upgrade pip

and then retry package installation.

If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

My host machine info:

I've double check the requirements packges, reinstall pip but still the same error
Any suggestion? many thanks advance.

Are you able to run cargo build --features=python? This will build the Rust bindings for python which is part of the step that's failing.

Alternatively, we're planning to release a new version of ERDOS in the next week with a new API and an improved build process. You can try it out on the redesign branch.

Thanks for your reply and I've try cargo build --features=python but I got the new error:

error: failed to download time v0.3.9

Caused by:
unable to get packages from source

Caused by:
failed to parse manifest at /home/strike/.cargo/registry/src/github.com-1ecc6299db9ec823/time-0.3.9/Cargo.toml

Caused by:
feature resolver is required

consider adding cargo-features = ["resolver"] to the manifest

According to the error, I did some dig in community and find some workaounrds, here are what I tried:

1. rustup update
2. eselect rust set 1
3. add ``cargo-features = ["resolver"]` at /home/strike/.cargo/registry/src/github.com-1ecc6299db9ec823/time-0.3.9/Cargo.toml
4. add ``cargo-features = ["resolver"]` at $PROJECT_ROOT/Cargo.toml

Unluckily, none of these works, so I'm waiting for your further suggestion and help.
Besides, I'll try the new branch you mentioned before, thanks again.

I just re-implement all the env and package, now the build process works fine, thanks.
