pip install matplotlib on termux failed

Question

I am trying to install matplolib on android device using termux, but have been failing.

I have installed libjpeg-turbo and zlib, and tried installing other packages libtiff, libwebp, openjpeg, and so on.

But it is still failing.(Error message has been changed though)

anyone solved this problem?

Answer 1

I'm not sure if it will help, but I personaly could not install Pillow and some other libraries on my termux without this (flags?):

LDFLAGS="-L/system/lib64/" CFLAGS="-I/data/data/com.termux/files/usr/include/" pip install matplotlib

It's probably an error that has to do with our phones using the "AArch64" ARM architecture.

Answer 2

Termux's package manager contains the matplotlib package.

So you can install matplotlib via

pkg install matplotlib

and after that matplotlib can be imported in the Python version (3.10.4 as of 2022/04/09) even one fails to configure pip to install matplotlib.

(You can see the actual dependencies by pkg show matplotlib.)
