How to use pocketsphinx with AnacondaPrompt

I installed pcketsphinx on Anaconda using conda-forge in this way.
conda install -c conda-forge pocketsphinx
And then I got the following message
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Why does it say "The following packages are not available from current channels:"?
How do I make pocketsphinx available to me?
I also tried pip install, but got an error.
pip install pocketsphinx

I'm using Anaconda3 and Python 3.7.4 and Windows 10 64bit.

I came across what looks like the same problem and was able to solve it with the following steps. Hopefully this will help you and others, at least to get started. Consider the following general points:
Anaconda/Miniconda had a version of gcc that was picked up as the default compiler and, it seems, was interfering. Make sure gcc is picking up the desired compiler. To see what compilers you have, start up a terminal window, type gcc+TAB (gcc followed by a tab). This should show all the versions you have on your system. Type gcc --version to see which version is the default. And which gcc to find out where it is located, e.g. /Users/PatrickT/miniconda/bin/gcc
You want to ensure that your system's PATH can find your compiler. This may be done by adding an export command to your bash profile. On Catalina, apparently, the bash profile information would be placed in .zshrc. To find this file, type COMMAND+SHIFT+E to make invisible files visible and look in your home directory (/Users/PatrickT in my case). For instance, add a line like export PATH="/usr/local/gcc-10/bin:$PATH". The path is of course dependent on your system.
To make sure miniconda was not interfering, I took it off the PATH altogether. I also installed the latest version of xcode from the apple binaries. Once I had an updated version of the gcc compiler found by my system, I was able to install pocketsphinx as well as other programs that I was having problems with, like kaldi or zlib.
Getting miniconda to work again without interfering with gcc is a problem I haven't solved. As soon as I put miniconda back on the PATH, the default gcc reverted to the miniconda version. To be continued...

You can:
pip install pipwin
and
pipwin install pocketsphinx
I was having the same issue and got into this site:

sdl.h error when installing pygame on Mac?

I'm trying to install pygame.
My envrionment is

I'm following the instructions on the Pygame site, namely using
pip install pygame
However this is failing with a fatal error, which can be summarised as fatal error:SDL.h filenot found The full install output is shown below.

The file SDL.h does exist when I search in finder, so i don't know why this install is failing.
I've tried the following to solve this but with no success.
installing with pip3 install pygame
installing with pip3 install pygame--2.0.0_dev4 option
And i've even tried downloading the SDL2 source and compiling.
They all fail (the SDL make fails chronically with errors around lzma.h
Has anyone got pygame running on macOS and Python 3.7.4 and can provide a list of detailed instructions and pre-requisites.

I just struggled with this same issue and was finally able to install pygame on a Mac with Mojave by using this command line:
pip3 install pygame --only-binary :all:
This will install a precompiled version of pygame and thus avoids the issue with missing header files (like SDL.h in your error message) which is occurring because pip is trying to compile pygame from source code that looks for these headers in /usr/include. With the latest updates to Mojave and Catalina, Apple no longer has a /usr/include directory. I did check the version of pygame installed with the --only-binary option and see it is a 2.0.0 dev version but so far it seems to work.

I was able to solve this issue by using easy_install pygame instead of pip. I suspect that it has something to do with python 3.8.

I struggled a lot in installing pygame on macOS Catalina. I tried creating the virtual env as well as many other options but Nothing worked for me. The default python is located in /usr/bin/python while the python3 that I installed is located in /Library/Frameworks/Python.framework/Versions/3.8/bin/python3 so instead of using pip install pygame i triedeasy_install-3.8 pygame and it worked for me and when I opened the bin folder in /Library/Frameworks/Python.framework/Versions/3.8 location it has an easy_install-3.8 file. I do not know much about it but I think it has something to do with the python3.8

pip install regex Fails to build on Anaconda python3.6.9 virtualenv

I'm using anaconda 64bits on a manjaro distribution. I created a python3.6 enviroment using conda create -n tensorflow python=3.6 anaconda.
I also installed pip install tensorflow-gpu==1.12 and conda install cudnnif that matters.
On my original python 3.7 outside of anaconda (/usr/bin/python3) it installs fine, but when I enter the virtualenv by conda activate tensorflow, and try to install by pip install regex==2017.4.5 it yelds an error.
Other versions of the package seem to be getting the same error, it is not version specific.
See the error message below:

Some things I noticed above:
Upon building, the error message pointed out file not recognized: file format not recognized
Something called "ld" exited a fail status on the building process collect2: error: ld returned 1 exit status. I suppose this is just to signify that something went wrong while builind on /run/ or /usr/temp, but it may be helpful.
I don't actually believe it's a problem with gcc, since other packages install fine.
I also don't believe it to be an error of system-wide dependencies, because outside of the virtualenv everything works fine.
And please keep in mind: I am using a manjaro, arch distributions don't have -dev or -devel packages (e.g. python-devel) to install separatelly. Normally those come included with the original package (i.e. python or python3).
Thanks for any help :).

I've searched a little more on the topic, and it seems that my OS is very much involved. The problem seems to be in kernel toolkit level stuff, and a bit more upstream than I imagine. Waiting for someone to close the question. Will post on Super User stack exchange.

Maybe you should try to using:
conda install regex
instead of pip.

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

Error updating pycups via pip

I'm running openSUSE Leap 42.1 and I just tried to update all the software in pip, using the following command:
for i in $(pip list|awk '{print $1}'); do pip install $i --upgrade;done
This hit a few errors, I had some missing devel dependencies, which I managed to fix, and most of the packages then updated fine, but one continues to fail, and I'm not sure why. The errors at this point became a bit cryptic and my google-fu was unable to find the answer. Can anyone advise why I'm getting this error, and whether there is a way to fix/work around?

Rolling back uninstall of pycups
Command "/usr/bin/python3 -c "import setuptools, tokenize;__file__='/tmp/pip-build-vpyfl_ln/pycups/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-zukh_f21-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-vpyfl_ln/pycups
I'm using the following pip:
pip 7.1.2 from /usr/lib/python3.4/site-packages (python 3.4)

The problem is this compiler flag: -Werror=declaration-after-statement. You need to tell the compiler not to turn this warning into an error by setting the CFLAGS environment variable:
CFLAGS=-Wno-error=declaration-after-statement pip install -U pycups
