fix #11753 close #11781 The virtualenv troubleshooting in the Python provider health checks is supposed to help the user determine whether running Python from Neovim (as in `system('python')` or `system(exepath('python'))`) will use the correct executable when a virtualenv is active. Currently however, it issues spurious warnings in legitimate setups, and conversely, fails to warn about potentially problematic ones. See https://github.com/neovim/neovim/issues/11753#issuecomment-578715584 for a more detailed analysis, but at a high level, this is due to two things: - the virtualenv check is part of the Python provider check defined in `s:check_python`, which uses a roundabout and sometimes erroneous way of determining the Python executable - more generally, it shouldn't be part of the provider check at all, because it's not really related to the Python *provider*, i.e. the Python executable which can communicate with Neovim via `pynvim`, but to the Python the user is editing source files for, which typically shouldn't even have `pynvim` installed This patch reimplements the virtualenv check and factors it out into its own separate function, which is however still kept in `health/provider.vim` alongside the rest of the Python troubleshooting, since troubleshooting all Python-related stuff in one place is probably a good idea in order to alleviate any potential confusion (e.g. users who run only provider checks might be left wondering whether their virtualenv Python was properly detected if the report only shows their global Python as the provider used by Neovim).

Neovim is a project that seeks to aggressively refactor Vim in order to:
- Simplify maintenance and encourage contributions
- Split the work between multiple developers
- Enable advanced UIs without modifications to the core
- Maximize extensibility
See the Introduction wiki page and Roadmap for more information.
Features
- Modern GUIs
- API access from any language including C/C++, C#, Clojure, D, Elixir, Go, Haskell, Java, JavaScript/Node.js, Julia, Lisp, Lua, Perl, Python, Racket, Ruby, Rust
- Embedded, scriptable terminal emulator
- Asynchronous job control
- Shared data (shada) among multiple editor instances
- XDG base directories support
- Compatible with most Vim plugins, including Ruby and Python plugins

Install from package
Pre-built packages for Windows, macOS, and Linux are found on the Releases page.
Managed packages are in Homebrew, Debian, Ubuntu, Fedora, Arch Linux, Gentoo, and more!
Install from source
The build is CMake-based, but a Makefile is provided as a convenience.
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
To install to a non-default location:
make CMAKE_INSTALL_PREFIX=/full/path/
make install
To skip bundled (third-party/*) dependencies:
- Install the dependencies using a package manager.
sudo apt install gperf luajit luarocks libuv1-dev libluajit-5.1-dev libunibilium-dev libmsgpack-dev libtermkey-dev libvterm-dev libutf8proc-dev sudo luarocks build mpack sudo luarocks build lpeg sudo luarocks build inspect - Build with
USE_BUNDLED=OFF:make CMAKE_BUILD_TYPE=RelWithDebInfo USE_BUNDLED=OFF sudo make install
To inspect the build, these CMake features are useful:
cmake --build build --target helplists all build targets.build/CMakeCache.txt(orcmake -LAH build/) contains the resolved values of all CMake variables.build/compile_commands.jsonshows the full compiler invocations for each translation unit.
See the Building Neovim wiki page for details.
Transitioning from Vim
See :help nvim-from-vim for instructions.
