ERROR: Failed building wheel for spacy

You could try python3 -m pip install --no-binary spacy chatterbot, which should tell pip to not build the wheel
Alternately python3 -m pip install --no-use-pep517 chatterbot.

I had the same problem while installing kivy through command prompt.
If you use Pycharm then there is an easy way to avoid these problems.
Open Pycharm-->GoTo Files-->Settings-->Project-->Python Interpreter--> + sign-->then search for what you want to install. Check the version which works for you and install it.
If you get an error then try and install other versions of it. That would solve the issue.

Try installing the python-dev version.
For python3.7
sudo apt-get install python3.7-dev
For python3.6
sudo apt-get install python3.6-dev

In one of the scenarios where if you are using Anaconda, then you have to install using this command:
conda install -c conda-forge spacy, hope this helps !!

I had this issue with MacOS for a different package. I found this warning in the log:
WARNING: Building wheel for bottleneck failed: [Errno 13] Permission denied: '/Users/avi/Library/Caches/pip/wheels/87'
Then I gave my user access to the pip/wheels directory and then the installation worked.

Easy, try to run this:
pip install pep517
And then try to install again
python3 -m pip install chatterbot

Installing pyodbc failed on Linux

I just run this command:

then I get below message and error:

I saw there is an error:
command 'x86_64-linux-gnu-gcc' failed with exit status 1
then I search in on google, it asked to run this:
sudo apt-get install python-dev
so, I run this but get below message:
steven81#PythonWEBVM:~$ sudo apt-get install python-dev

Reading state information... Done
python-dev is already the newest version (2.7.12-1~16.04).
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.
so what's the problem and how to install pyodbc correctlly?

For anyone looking for the pyodbc install to connect to SQLServer from Linux(ubuntu).
sudo apt-get install unixodbc-dev
sudo apt-get install python3-dev
python3 -m pip install pyodbc

pycurl link error after upgrade from Yosemite to High Sierra

I just upgraded from Yosemite to High Sierra, which worked quite well, with the only exception that I have a bug in pycurl.
import pycurl
ImportError: No module named pycurl
so I did
pip uninstall pycurl
and
pip install --no-cache-dir --compile pycurl
but now it results in a clang error

any idea what is going on here?

this fixed it...

Install big float on mac OS X

I am trying to install big float on OS X but i am encountering multiple issues.
I have installed amp without any problem, but when I have tried to install mpfr I got this error:
Warning: mpfr-3.1.5 already installed, it's just not linked.
What does this mean? (I am using Homebrew).
Then, obviously, if I try to install bigfloat it doesn't work and i get this error:

You must install python-devel
In OS X try to uninstall and install again:
brew uninstall python
brew install python
Also according to this issue, Osx GCC (which is just a symlink to clang) doesn't ship with OpenMP support out of the box. You can install GCC with OpenMP.
brew install gcc --without-multilib

Python pip cannot install zbarlight: error: command 'gcc' failed with exit status 1

First of all I installed Python 3.5.1:
yum -y install zbar gcc gcc-c++ kernel-devel
./configure --enable-shared --prefix=/usr/local LDFLAGS="-Wl,--rpath=/usr/local/lib"
make && make install
Tried to install zbarlight pypi package but failed:
src/zbarlight/_zbarlight.c:137: error: ‘ZBAR_QRCODE’ undeclared (first use in this function)
src/zbarlight/_zbarlight.c:138: error: ‘ZBAR_CODE128’ undeclared (first use in this function)

How do I fix that? I tried pip3.5 -v but doesn't show any more meaningful error.

Had to install
yum install zbar-devel
