I generated a project based on this site and ran cargo build and got the following.

C:\train-rust-esp32\test>cargo build      
   Compiling esp-idf-sys v0.31.5
error: failed to run custom build command for `esp-idf-sys v0.31.5`

Using custom user-supplied esp-idf repository at 'C:\Users<user name>\esp\esp-idf' (detected from env variable IDF_PATH)

This is the offending line. You need to remove $IDF_PATH from your environment, unless you are using a properly activated environment (running export.sh inside esp-idf).

Does running python --version succeed? If it does, this is strange indeed.

The .cargo/config.toml looks like this

[build]
# Uncomment the relevant target for your chip here (ESP32, ESP32-S2, ESP32-S3 or ESP32-C3)
target = "xtensa-esp32-espidf"
#target = "xtensa-esp32s2-espidf"
#target = "xtensa-esp32s3-espidf"
#target = "riscv32imc-esp-espidf"

[target.xtensa-esp32-espidf]
linker = "ldproxy"

[target.xtensa-esp32s2-espidf]
linker = "ldproxy"

[target.xtensa-esp32s3-espidf]
linker = "ldproxy"

[target.riscv32imc-esp-espidf]
linker = "ldproxy"

# Future - necessary for the experimental "native build" of esp-idf-sys with ESP32C3
# See also https://github.com/ivmarkov/embuild/issues/16
rustflags = ["-C", "default-linker-libraries"]

[unstable]

build-std = ["std", "panic_abort"]
#build-std-features = ["panic_immediate_abort"] # Required for older ESP-IDF versions without a realpath implementation

[env]
# Note: these variables are not used when using pio builder
# Enables the esp-idf-sys "native" build feature (`cargo build --features native`) to build against ESP-IDF stable (v4.4)
# ESP_IDF_VERSION = { value = "branch:release/v4.4" }
# Enables the esp-idf-sys "native" build feature (`cargo build --features native`) to build against ESP-IDF master (mainline)
#ESP_IDF_VERSION = { value = "master" }
IDF_PATH = "C:\\Users\\<user name>\\esp\\esp-idf"
ESP_IDF_TOOLS_INSTALL_DIR = "custom:C:\\Users\\<user name>\\.espressif"
# ESP_IDF_REPOSITORY = "https://github.com/espressif/esp-idf.git"
# ESP_IDF_SDKCONFIG_DEFAULTS = ""
# ESP_IDF_SDKCONFIG = ""
MCU = "esp32"

I added the [env] part with reference to the README.md of esp-idf-sys.

Before I added this, I was getting errors like this.

  Error: Could not install esp-idf

  Caused by:
      0: Failed to locate python. Is python installed and in your $PATH?
      1: command '"python" "--version"' failed to start

Because of the "Could not install esp-idf" message, I had to specify the path to the esp-idf installed in VSCode's "Espressif IDF".

python --version

C:\train-rust-esp32\test>python --version
Python 3.10.2

I was able to build successfully

What we did

Installed Python 3.10.4 with the official Python installer.
Select "Add to PATH" during installation.

I was using pytnon with pyenv-win, but found that this does not work.

I don't know why I shouldn't have to install a new one, since the path should be through pyenv alone.

Was the problem with embuild in the first place, rather than esp-idf-sys...?

I just looked at the pyenv docs, it seems like it adds a $PATH entry to the user $PATH, whereas I think the python installer uses the system $PATH. That's my best guess, but python on windows is somewhat wonky 😅. Glad you managed to get it built, closing for now :).

I was using python with pyenv-win, but found that this does not work.

I don't know why I shouldn't have to install a new one, since the path should be through pyenv alone.

I can only speculate as I don't know how pyenv-win does its python shims. This issue relates to how we run python (for example in the embuild::python::check_python_at_least function).

Currently, we use the std::process::Command API and it's not really documented how that API deals with file extensions on Windows. But from reading the code and going though some issues it may be that it actually always adds a .exe extension if the program has no file extension (in our case we use just python as the program path) (see rust-lang/rust#37519, rust-lang/cargo#10455 and stdlib impl).

So even though there is python and python.bat in $PATH it actually runs python.exe which is not found and fails.

I just looked at the pyenv docs, it seems like it adds a $PATH entry to the user $PATH, whereas I think the python installer uses the system $PATH.

That shouldn't be an issue, at least this SuperUser answer says that the system $PATH is prepended to the user $PATH.
