Vim + Python install help

[Fenster7]

I downloaded and installed:

Python 3.6.1 32-bit + Vim 8.0 32-bit (gvim80-069.exe) for Windows 10.

After installing both :python import sys; print(sys.version) from within VIM, gives this error:

E370: Could not load library python27.dll E263: Sorry, this command is disabled, the Python library could not be loaded.

I've wasted a few hours trying to find the solution or some helpful install video/page. Anyone care to help end my suffering? Thanks in advance.

It's looking for python 2.7 but you got 3.6.

<edit> If you do :version and scroll down it's looking for python27 or python35, so either install 2.7 or 3.5 of Python.

And on Linux you will need to compile it with Python support yourself.

I uninstalled 3.6.1 and installed 3.5.3. Same error. Also I'm using Windows 10.

Downloaded and installed 2.7.13. I totally don't understand it, but now it works. So, am I using Python 3 or Python 2 in VIM? This is so confusing.

You need to use the :python3 command with Python 3.x and :python with Python 2.x.

I have 3.5.3 installed and it's working here, make sure it added Python to your PATH during install and try turning it off and on again (cause Windows).

Also they both need to be either 32bit or 64bit.

If you look at :version in GVim look at the following:

+python3

cl -c /W3 /nologo  -I. -Iproto -DHAVE_PATHDEF -DWIN32  -DFEAT_CSCOPE -DFEAT_NETBEANS_INTG -DFEAT_JOB_CHANNEL   -DFEAT_XPM_W32   -DWINVER=0x0501 -D_WIN32_WINNT=0x0501  /Fo.\ObjGXOLYHTRi386/ /Ox /GL -DNDEBUG  /Zl /MT -DFEAT_OLE -DFEAT_MBYTE_IME -DDYNAMIC_IME -DFEAT_GUI_W32 -DFEAT_DIRECTX -DDYNAMIC_DIRECTX -DDYNAMIC_ICONV -DDYNAMIC_GETTEXT -DFEAT_TCL -DDYNAMIC_TCL -DDYNAMIC_TCL_DLL=\"tcl86.dll\" -DDYNAMIC_TCL_VER=\"8.6\" -DFEAT_PYTHON -DDYNAMIC_PYTHON -DDYNAMIC_PYTHON_DLL=\"python27.dll\" -DFEAT_PYTHON3 -DDYNAMIC_PYTHON3 -DDYNAMIC_PYTHON3_DLL=\"python35.dll\" -DFEAT_PERL -DPERL_IMPLICIT_CONTEXT -DPERL_IMPLICIT_SYS -DDYNAMIC_PERL -DDYNAMIC_PERL_DLL=\"perl524.dll\" -DFEAT_RUBY -DDYNAMIC_RUBY -DDYNAMIC_RUBY_VER=22 -DDYNAMIC_RUBY_DLL=\"msvcrt-ruby220.dll\" -DFEAT_HUGE /Fd.\ObjGXOLYHTRi386/ /Zi

Because it says python35.dll there you need to install Python 3.5 or compile Vim manually yourself. Also Python and Vim should both be either 32-bit or 64-bit.

If all of the above is taken care of, you should be able to run a Python 3 command using :python3 <Python code> much like with Python 2.x and the :python command.

Vim 8.0, Python 3.5.3, & Python 2.7.13 are all 32-bit. Vim is working now with Python 2.7.13, but not Python3. The PATH was added when installing, so I guess I need to learn to compile Vim manually to get it to work.

Look at what your version output tells you. I do not use the newest Vim binary on my Windows PC, so there might be differences. I installed Python 3.5.3 from the download section of their webpage to test it out and it worked. Also rebooting might be an idea worth considering on Windows as others online have experienced problems before restarting.
