ERROR: Failed building wheel for cryptography

trying to update to latest version and this is the error I get
ERROR: Failed building wheel for cryptography
Failed to build cryptography
ERROR: Could not build wheels for cryptography, which is required to install pyproject.toml-based projects

That issue, I guess:

I have the same problem. The newest pip. I did everything from the instruction and still have:

`Building wheels for collected packages: cryptography

      If you are seeing a compilation error please try the following steps to
      successfully install cryptography:
      1) Upgrade to the latest pip and try again. This will fix errors for most
         users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
      2) Read https://cryptography.io/en/latest/installation.html for specific
         instructions for your platform.
      3) Check our frequently asked questions for more information:
         https://cryptography.io/en/latest/faq.html
      4) Ensure you have a recent Rust toolchain installed:
         https://cryptography.io/en/latest/installation.html#rust
      5) If you are experiencing issues with Rust for *this release only* you may
         set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.

  ERROR: Failed building wheel for cryptography`

I believe you need to install cargo.

sudo apt install cargo

this is what I did just before the pip3 install command

export CRYPTOGRAPHY_DONT_BUILD_RUST=1

pip3 install --upgrade homeassistant

It works, thank you so much!

Cargo didn’t fix the problem but
export CRYPTOGRAPHY_DONT_BUILD_RUST=1

did the trick!!!

I’m trying to build Python 3.8.12 but I’m stuck with the cryptography build error, no way to get rid of it. I tried export, setting the value in .env, passing the var to the pip install command… No way! I don’t know where to look at, any hint is welcome. Thanks

I also get this error, when trying to upgrade to 2021.12.3. I have tried with

export CRYPTOGRAPHY_DONT_BUILD_RUST=1

but no luck. Also installing cargo does not help. Any ideas?

The export trick doesn’t work anymore in 2021.12, due to “cryptography” being bumped to 3.5.
That did the trick for me, i.e. installing a newer rust/cargo from origin.

Excellent, that worked. To clarify, these are the commands I ran:
sudo apt remove rustc
sudo curl https://sh.rustup.rs -sSf | sh

Thanks so much!

Same problem even after upgrade rust. My log.
rustc 1.57.0

Hi,

for armv7 during the cargo and rustc installation

curl https://sh.rustup.rs -sSf | sh

please first select option 2 and chage it to “armv7-unknown-linux-gnueabihf”, rest just enter defaults and then select option 1 and install. After that type:

source $HOME/.cargo/env

To double check if it is ok, just type

rustc – version

to see if it is OK.

Then run again installation of HA and the Cryptography should be properly built.

Good luck :wink:

P.S. be sure to unistall previous version via:

sudo apt remove rustc cargo

If you need to unistall previous cargo and rustc, use:

rustup self uninstall

Hi,

I found a workaround on one the debian bug reports. I seams to be a second bug with rust and git. If I set the following variables I was able to install the required cryptography 35.0.0 package:

export CRYPTOGRAPHY_DONT_BUILD_RUST=1
export CARGO_NET_GIT_FETCH_WITH_CLI=true

Hi, should I update Rust in pip env or in my main account? I updated as a root user but in pip env HA says me: error: can’t find Rust compiler

EDIT
Helped me adding
export PATH=$PATH:~/.cargo/bin
after instalation of Rush from
curl [https://sh.rustup.rs](https://sh.rustup.rs/) -sSf | sh

This did it for me! Running
rustup self uninstall
first was important.

I’m on a raspberry pi. To make sure I was on an ARMv7 processor architecture I ran:

cat /proc/cpuinfo

yet another similar, but slightly different issue:

cryptography==35 on a Pi 3b, with Rust installed via rustup, the command rustc -vV states that my platform is armv7-unknown-linux-gnueabihf – however, cryptography wants to use arm-unknown-linux-gnueabihf, which must be installed separately.

I used:

  • install rust locally via rustup, and make sure it’s on the path
  • rustup target add arm-unknown-linux-gnueabihf
  • Incidentally, I am also using a system with two python versions installed, and needed to export PYO3_CROSS_PYTHON_VERSION=3.8

…this finally worked.

Hi, new version HA and still the same:
error: can’t find Rust compiler

I’ve instaled from curl https://sh.rustup.rs -sSf | sh, set source $HOME/.cargo/env

and nothing change. Why with each a new version of HA is the same problem?

same here! everyone has a hint how to do but what is the official straightforward way to upgrade to 2022.11.xx?
solution can’t be so tricky :frowning:

same here! 2022.11.2
