Too many issues will kill our team's development velocity, drastically.
Make sure you have checked all steps below.

Prerequisite

• Make sure your problem is not listed in the common build problems.
• Make sure no duplicated issue has already been reported in the pyenv issues. You should look for closed issues, too.

  • GitHub issues is opened mainly for development purposes. If you want to ask someone to help solving your problem, go to some community site like Gitter, StackOverflow, etc.
• Make sure your problem is not derived from packaging (e.g. Homebrew).
  • Please refer to the package documentation for the installation issues, etc.
• Make sure your problem is not derived from plugins.
  • This repository is maintaining pyenv and the default python-build plugin only. Please refrain from reporting issues of other plugins here.

Hi, I'm using Ubuntu 16.04 LTS, I installed pyenv by Linuxbrew. When I tried to install Python 3.7.5, I got this:

Downloading Python-3.7.5.tar.xz...
-> https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tar.xz
Installing Python-3.7.5...
python-build: use readline from homebrew
WARNING: The Python readline extension was not compiled. Missing the GNU readline lib?
Installed Python-3.7.5 to /home/chi/.pyenv/versions/3.7.5

Python installed by pyenv DO lack readline.

But both Linuxbrew and apt-tool already installed readline:

$ sudo apt list libreadline-dev
libreadline-dev/xenial,now 6.3-8ubuntu2 amd64 [installed]
$ brew info readline
readline: stable 8.0.1 (bottled)
Library for command-line editing

So I'm confused if pyenv really uses readline from homebrew?
