i have installed all the necessary libraries and valabind and swig. Post that when i install lang-python i get:

r2pm -i lang-python

Module version mismatch /root/.local/share/radare2/plugins/lang_python.so (3.1.2) vs (3.9)

It creates a lang-python.so but when i try to import it within a plugin it says module not found.Please help with this.I think its a path issue i dont know how to fix it.

from radare2-bindings.

Also when i go to r2 console:
[0x00000000]> #!
c: (LGPL) C language extension
cpipe: (LGPL) r2pipe scripting in C
vala: (LGPL) Vala language extension
rust: (MIT) Rust language extension
zig: (MIT) Zig language extension
pipe: (LGPL) Use #!pipe node script.js
lib: (LGPL) Load libs directly into r2

In my opinion, lang-python should be decoupled from the radare2-bindings repo, since it's the most commonly installed plugin anyway, will reduce the installation time and remove the need for all these deps. It will be possible to simplify the building as well. Probably duktape too, but that's it. There is a less interest for everything else.
@radare @thestr4ng3r @ITAYC0HEN @xarkes what do you think?

i am using a fresh kali image this time 2019.1 and post installation on lang-python when i try to import it using r2 i get:
r2: symbol lookup error: /root/.local/share/radare2/plugins/lang_python.so: undefined symbol: r_buf_data

To resolve this error i installed r2 again using apt but then i get module version mismatch error and r2lang is not found...

@JIRAya-Sama show the output of r2 -version. I think you have too old radare2.

from radare2-bindings.

r2 -version

radare2 3.1.2 0 @ linux-x86-64 git.3.1.2
commit: HEAD build: 2018-12-11__11:34:51

i updated r2 using apt install....but then i get module version mismatch with lang-python

from radare2-bindings.

Way too old. Remove the distribution one and install from the sources.

Once you installed, you can just clone https://github.com/radareorg/radare2-rlang and run "make".
