How to include Python Pillow as Homebrew formula requisite?

How to include Python Pillow as Homebrew formula requisite? - python

I used to use Homebrew tap formulas to distribute my self maintained programs. However, it is imposible for me to do with some programs which use Pillow, because Homebrew fails when try to install it isolate.
Example of a recipe which uses Pillow:
class Monoshape < Formula
include Language::Python::Virtualenv
desc "Extracts monochromatic shapes"
homepage "https://github.com/GlezSeoane/monoshape"
url "https://github.com/GlezSeoane/monoshape/archive/v1.0.tar.gz"
sha256 "6edbecfc60db6f91fba6e520769f811009743eec89d655c54e4e6006ad5b0dbb"
depends_on "python"
resource "filetype" do
url "https://files.pythonhosted.org/packages/e8/53/298887541ae479f8467d4d23e028c6d15f9811da25c582297fd3869666b7/filetype-1.0.5.tar.gz"
sha256 "17a3b885f19034da29640b083d767e0f13c2dcb5dcc267945c8b6e5a5a9013c7"
end
resource "Pillow" do
url "https://files.pythonhosted.org/packages/51/fe/18125dc680720e4c3086dd3f5f95d80057c41ab98326877fc7d3ff6d0ee5/Pillow-6.1.0.tar.gz"
sha256 "0804f77cb1e9b6dbd37601cee11283bba39a8d44b9ddb053400c58e0c0d7d9de"
end
def install
virtualenv_install_with_resources
man1.install "manpages/monoshape.1"
end
test do
system "python", "-c", "'import monoshape.__main__'"
end
end
Homebrew error output when try to use the formula:
brew reinstall --verbose --debug ./Formula/monoshape.rb

You likely need to include additional depends_on clauses to help Pillow locate compiled libraries: e.g., depends_on "openjpeg" (which provides openjpeg.h).

I already tried with pip3 install imread --no-cache-dir as I read somewhere else but didn't work at all. I already did brew install gcc but it didn't work out. I deleted and reinstalled the command line tools through terminal with xcode-select --install but still doesn't work.
I can read in the first lines that it says "Requirement already satisfied" but I checked and imread is definitely not installed.
Environment:
macOS Catalina 10.15.4
python 3.7.7 (I tried installing it in python 2.7 using just pip but
still doesn't work).
pip version = pip 20.1 from /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)
if anyone can find the solution I would be very grateful! I've been looking for hours for the solution and I can't find it!

It says quite clearly:
sh: pkg-config: command not found
So you have to install pkg-config and try again.

You need to install pkg-config package. For MacOSX you may find it either in Brew or in other software collections like thus sourceforge repository
The second (and perhaps the actual) error is the error with gcc. Considering the line
imread/lib/base.h:138:46: warning: rvalue references are a C++11 extension [-Wc++11-extensions]
void push_back(std::unique_ptr<Image>&& p) { content.push_back(p.release()); }
I expect your gcc being quite old. What is its actual version? Try to run gcc -v to find out.
Update:
As a non-Mac user I would go with gcc :-) . To install gcc-9+ from brew, use brew install gcc command. Then check that gcc and g++ are actually installed:
g++-9 --version
I would also check the C++ standard library as suggested in https://stackoverflow.com/a/17940219/3159253 :
`gcc-9 -print-prog-name=cc1plus` -v
Make sure the paths point to relatively recent version of C++ library, not to 4.2.1 as in your comment.
You should then explicitly use it when running pip:
CC=gcc-9 pip install imread

lxml: error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

I've seen some posts on lxml installing problems, but none of the answers I found was of any help. Many said to install python-dev, libxml2 and libxslt to solve the problem. They are already installed, but I still get the following outcome (keep in mind that I'm installing everything locally using virtualenv):

What does warning: no previously-included files found matching '*.py' mean?
/usr/bin/ld: cannot find -lz what is -lz? How to install it?

The relevant error is this:
/usr/bin/ld: cannot find -lz
...which indicates that the linker couldn't find libz.so, which means you don't have zlib installed in a location in your library search path.
Install zlib; the method for doing so depends on your operating system, so there's no generic answer. It might be something like:
sudo apt-get install zlib-dev # on a Debian derivative
sudo apt-get install zlib1g-dev # on Ubuntu 14.04 (see below)
sudo yum install zlib-devel # on a Red Hat derivative
sudo port install zlib # on a ports-based system
sudo pacman -S zlib # on Arch Linux
or any number of other things as appropriate.
Assuming you want to find the appropriate package name for a given version of Ubuntu, one can search for the package containing libz.so on packages.ubuntu.com; the linked results are for Trusty.

Django MySQLClient pip compile failure on Linux

Django documentation as of v1.8 recommends using mysqlclient connector for the framework. I'm attempting to pip install the package on Ubuntu 14.04 with Python 3.4 and running into a GCC error that I'm unable to find reference to. I'm not an expert on compiling software, so was hoping somebody can see the solution.
I believe I'm getting a linking error. I have installed distro specific mysql headers, but it looked like they were only applicable to Python 2.7.x.
Not sure how much of this is useful so apologies for the long paste, but here's the error log:

It looks like you're missing zlib; you'll want to install it: apt-get install zlib1g-dev
I also suggest reading over the README and confirming you have all other dependencies met: https://github.com/dccmx/mysqldb/blob/master/README
Also, I suggest using mysqlclient over MySQLdb as its a fork of MySQLdb and what Django recommends.

using this MySQL Connector worked for me:
https://dev.mysql.com/downloads/connector/python/
https://dev.mysql.com/doc/connector-python/en/connector-python-installation.html

Improperly configured: Usage of the xml aspects requires lxml and defusedxml

I'm trying to use XML for a Django website I'm making but I ran into the following error when I set the page to display xml:
ImproperlyConfigured at /articles/api/article/
Usage of the XML aspects requires lxml and defusedxml.
The page was working the way I wanted it to when I set it to display json. And I thought I installed lxml and defusedxml when I used the command
pip install defusedxml "lxml>=3"
But I got this log on the command line. It was installing fine until some errors popped up:

I looked at similar posts about errors when installing lxml but these posts didn't have the same error messages as mine. I looked at the lxml documentation and tried to install it according to the documentation, but I still cannot get lxml or defusedxml installed.
I don't know what I'm installing incorrectly or what to do. But I appreciate any help that you can give me. Thank you.

The error "/usr/bin/ld: cannot find -lz": that means you don't have zlib-dev or zlib1g-dev in installed depending on your linux distribution, try install first this library.

ImportError: No module named lxml.html when creating scrapy project

I'm on OS 10.9.5 and get the following error when I try to create a scrapy project:
Traceback (most recent call last):

I first tried to uninstall and then reinstall scrapy using pip. I'm not sure whether the problem is actually that something went wrong during the installation of scrapy. I get the following output when installing scrapy:

Can anybody please help?

The problem was this part:
You have not agreed to the Xcode license agreements, please run 'xcodebuild -license' (for user-level acceptance) or 'sudo xcodebuild -license' (for system-wide acceptance) from within a Terminal window to review and agree to the Xcode license agreements.
Running sudo xcodebuild -license and reinstalling scrapy solved the problem.
