Question

我正在尝试通过pyenv在我的新ArchLinux安装

上安装python

pyenv install 3.5.1Downloading Python-3.5.1.tar.xz...
-> https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tar.xz
Installing Python-3.5.1...
ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?

Please consult to the Wiki page to fix the problem.

Ignoring ensurepip failure: pip 7.1.2 requires SSL/TLS

由于缺少OpenSSL支持而导致错误。我在之前的Arch安装中运行它，但我不记得我当时做了什么。

Wiki中的常见问题解答不提供可行的解决方案

Answer 1

请试试。：

CFLAGS=-I/usr/include/openssl-1.0 \
LDFLAGS=-L/usr/lib64/openssl-1.0 \
pyenv install -v 3.5.1

ArchLinux包：

$ pacman -Q | grep openssl
openssl 1.1.0.e-1
openssl-1.0 1.0.2.k-3
python-pyopenssl 17.0.0-1
python2-pyopenssl 17.0.0-1

Answer 2

pyvenv FAQ mention an issue similar to what you are reporting。他们的解决方案是使用

CFLAGS=-I/usr/include/openssl \
LDFLAGS=-L/usr/lib64 \
pyenv install -v 3.5.1

此外，不是Python需要SSL而只是pip。 Arch拥有自己的Python 3包compiles with --without-ensurepip，所以你可以尝试

CONFIGURE_OPTS="--without-ensurepip" \
pyenv install -v 3.5.1

在Archlinux上通过Pyenv编译Python但缺少OpenSSL
