在 Archlinux 上通过 Pyenv 编译 Python 但缺少 OpenSSL

Compiling Python via Pyenv on Archlinux but missing OpenSSL

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

并且由于缺少 OpenSSL 支持而失败。我在之前的 Arch 安装中有它 运行,但我不记得我当时做了什么。

Wiki 中的常见问题解答未提供有效的解决方案

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

另外,Python 不需要 SSL,而只需要 pip。 Arch 自己的 Python 3 包 compiles with --without-ensurepip,所以你可以试试

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

请试一试:

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