Cant install cryptography for python.

Opened this issue ยท 20 comments

When i try to install cryptography using pip i get an error:
Complete output from command python setup.py egg_info:

    ```

No working compiler found, or bogus compiler options passed to
the compiler from Python's standard "distutils" module. See
the error messages above. Likely, the problem is not related
to CFFI but generic to the setup.py of any Python package that
tries to compile C code. (Hints: on OS/X 10.8, for errors about
-mno-fused-madd see http://stackoverflow.com/questions/22313407/
Otherwise, see https://wiki.python.org/moin/CompLangPython or
the IRC channel #python on irc.freenode.net.)

No working compiler found, do you have clang installed, and python-dev?

No i did not, after installing both with pkg install and then retrying, i get this:

$ pip install cryptography

run pkg install libcrypt-dev then retry
crypt.h file is in that package

@vishalbiswas same error except this time it is:
#include <ffi.h>

pkg install libffi-dev now and try again

@vishalbiswas it works, thank you so much.

@o-gourari i already installed both of them,but i still cant install cryptography

What should i do?

@XSecr3t that is not the actual error. The real error should be somewhere above the last error message

@vishalbiswas

I think is it errors,cause every i want install cryptography the colour of the text is red on last errors above

@XSecr3t can you paste the whole output?

@vidhalbiswas

Sureee..

Finish thats the errors what i said

Termux has upgraded to OpenSSL 1.1.1, but the cryptography package has not been upgraded yet. Checkout this issue -> pyca/cryptography#4197

@XSecr3t You can't install openssl packages provided by me ? They are here: #2847

@vishalbiswas
Well unfortunately i already install SSL 1.1.1.2 Version ,so what i gonna do for now?

@xeffyr

I start rebuild my termux package from zero again and already install SSL that you give for me,but still isn't working bro,

you have to install both openssl and openssl-dev, if you still get errors then post them as well

@vishalbiswas

Like this?
openssl-dev_1.1.1-2_aarch64.deb
openssl_1.1.1-2_aarch64.deb

Both of them already installed but still not working for me to install cryptography

  =============================DEBUG ASSISTANCE=============================
  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: 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.
---------------------------------------- ERROR: Failed building wheel for cryptography
Failed to build cryptography ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly

Anyone show me the solution of this error while installing cryptography

@Avi-hs Just read the error message, it already provides a possible solution:

... If you did intend to build this package from source, try installing a Rust compiler from your system package manager...

So

  • Termux package manager is pkg (apt).
  • pkg search Rust will show that Rust compiler package is rust.

Resulting command will be pkg install rust.
