I try to install Django channels and I get this error how to fix it?
=============================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`.

Upgrading pip worked for me.

Hi Guys, I am trying to install spacy model == 2.3.5 but I am getting this error, please help me!
Try using python 3.6-3.9 instead, where there are binary wheels for pip install to use instead of having to compile from source.
(This is a conflict with python 3.10 and some generated .cpp files in the source package. Python 3.10 wasn't released yet when this version was published.)
I had the similar error while executing pip install -r requirements.txt but for aiohttp module:
socket.c -o build/temp.linux-armv8l-cpython-311/aiohttp/_websocket.o
aiohttp/_websocket.c:198:12: fatal error: 'longintrepr.h' file not found
#include "longintrepr.h"
^~~~~~~ 1 error generated.
error: command '/data/data/com.termux/files/usr/bin/arm-linux-androideabi-clang'
failed with exit code 1
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for aiohttp
Failed to build aiohttp
ERROR: Could not build wheels for aiohttp, which is required to install
pyproject.toml-based projects
Just in case I will leave here solution to my error. This error is specific to Python 3.11 version. On Python with 3.10.6 version installation went fine.
To solve it I needed to update requirements.txt.
Not working versions of modules with Python 3.11:
aiohttp==3.8.1
yarl==1.4.2
frozenlist==1.3.0
Working versions:
aiohttp==3.8.2
yarl==1.8.1
frozenlist==1.3.1

https://github.com/aio-libs/aiohttp/issues/6600
https://github.com/aio-libs/yarl/issues/706
https://github.com/aio-libs/frozenlist/issues/305
Try using:
!pip install spacy==2.3.5
Do not give space between == and 2.3.5
If you give any space between equal sign and version, it may give error.
I'm attempting to install a package I recently create into a Heroku app. It seems that Heroku uses an older version of pip which prevents my package from installing correctly. I repeated the process with repl.it to see what happens and here is what I get:

You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Repl.it: package installation success
Traceback (most recent call last):
File "python", line 1, in <module>

Line 1 of my code (the only line) is import zoho_crm
This is also the same error I get in Heroku.
I have no problems updating pip on my local machine, but the update with these cloud services seems to update but doesn't stick.
Any suggestions?
That version warning is only warning and can be safely ignored now. Your problem has nothing to do with pip, the problem is caused by the broken package zoho_crm — it doesn't contain anything installable, neither python modules nor packages.
Just trying to run a
pip install CrossMap
on OSX 10.11.6 with a brew installed python (version 2.7.12) and pip (version 9.0.1) and running into this error:
htslib/hts_os.c:30:10: fatal error: 'os/rand.c' file not found
#include "os/rand.c"
^
1 error generated.
error: command 'clang' failed with exit status 1
I have looked everywhere for information on this error and it has come up empty. Where does this dependency come from and how do I install it?
Thanks!
CrossMap depends on pysam which is a wrapper for sam tools. You need to install htslib before compiling pysam.
I'm trying to install PyOpenSSL 0.13 on my Macbook Pro (OSX version 10.11, El-Capitan). But it keeps failing. These are the steps I took
Download and install Command Line Tools (OSX 10.11) for Xcode 7.3.1 from here
$ virtualenv my-new-virtualenv
$ source my-new-virtualenv/bin/activate
$ pip install pyopenssl==0.13
When I do step #4, I get the following error:
OpenSSL/crypto/x509.h:17:10: fatal error: 'openssl/ssl.h' file not found
#include <openssl/ssl.h>
^
1 error generated.
error: command 'cc' failed with exit status 1
----------------------------------------
Failed building wheel for pyopenssl
Here is the entire trace showing that error.
Why am I getting this error and how can I fix it??
It appears you are missing the OpenSSL development headers, as mentioned by #Klaus D. This most likely happened because due to upgrading to El Capitan, these development headers were broken. It can usually be fixed by reinstalling your command line tools.
If you have Homebrew, run this code:
brew install openssl
Also, just out of curiosity, is there a particular reason why you want to use version 0.13? When I did $ pip install pyopenssl==0.14 I got no errors. See the bit on pyOpenSSL's documentation:
I have the following environment:
Linux Mint17.1 which comes pre-installed with python 2.7.6.
I setup an altinstall for python 3.3.5

I am trying to install TA-Lib in the virtual env but am not having any success.
If I try to install with:
./easy_install TA-Lib
I get the following error:

I get the following error:

So basically both approaches result in a final error of:

I have no problem installing other packages such as numpy, pandas, matplotlib etc in the virtualenv. It is just TA-Lib that is not working.
You don't have installed underlying ta-lib library. You can find more info on the project site https://github.com/mrjbq7/ta-lib :
Sometimes installation will produce build errors like this:
func.c:256:28: fatal error: ta-lib/ta_libc.h: No such file or directory compilation terminated.
This typically means that it can't find the underlying TA-Lib library, a dependency which needs to be installed.
