Hi,

I guess this will be fixed on next release with this PR #4364

[QuaiGoner]

Hello. can i bypass the error manually?

[Joulinar]

@MichaIng
is there a way to overcome the situation until 7.2 has been released?

[MichaIng]

Since it requires multiple lines to be added, at least there is no trivial one-liner. But you could apply the change to /boot/dietpi/dietpi-software: https://github.com/MichaIng/DietPi/pull/4364/files#diff-98445566b948cc76bb45181ccd463ee93a7a441dbc8b25763d1b88f05f4ef8c5

• Remove the red line and add the green lines.
• The Python version increment is not required.

Thx @MichaIng !

I'll mark this as closed. Feel free to reopen if required.

Hello, I try to install Home Assistant on Rpi2 but installation failed on Rust:

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  If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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.
  
  This package requires Rust >=1.41.0.

Upgrade pip don't work, command not found.

[Joulinar]

Could you share some more system details.

Required Information

• DietPi version | cat /boot/dietpi/.version
• Distro version | echo $G_DISTRO_NAME $G_RASPBIAN
• Kernel version | uname -a
• SBC model | echo $G_HW_MODEL_NAME or (EG: RPi3)

Hi, @Joulinar I download last Rpi image Armv7-32bit and install it on Raspberry Pi 2 model B. I'm not home now so I cannot give You more details.
Regards.

[Joulinar]

Ah yeah I remember that we had an issues once where cryptography requires rust to build now. Usually it was impacting ARMv8 only, as on 32bit we download pre-compiled packages from piwheels.org. #4104

Ok something we need to have a look how to bypass.

[PrzemekSkw]

OK, thanks. I will test Domoticz with my home automation for now :)
Regards.

[MichaIng]

Actually there are pre-compiled wheels available for aarch64 at PyPI, but probably not for the Python version compiled when installing HA. I'll try to replicate.

[Joulinar]

@MichaIng actually it's ARMv7 and I could replicate on my RPi3B+

[MichaIng]

Python 3.7 and 3.9 wheels are shipped by piwheels: https://piwheels.org/project/cryptography/
We simply need to bump the Python version for HA to 3.9.
