Python 3.7+ 源码安装
安装 Python
- 通过 python 官网下载源码包
- 通过 yum 安装依赖包
- 解压编译并安装
#安装依赖包
yum -y install bzip* ncurses* gdbm* libpcap* xz* libffi* sqlite* tk* libuuid* readline* zlib*
#解包源码包
tar -xf Python-3.8.0.tgz
mkdir /opt/sdks/versions/python3.8.0
#编译并安装
./configure -prefix=/opt/sdks/versions/python3.8.0
make & make install
常见错误
OpenSSL依赖问题
因openssl 1.0.1存在安全问题，python3自3.7版本后要求依赖openssl 1.0.2以上或libressl；错误提示如下：
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_P
-
安装libressl
python3.7以上建议使用libressl代替openssl，故需通过源码编译安装libressl# 下载源码包 wget https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-3.0.2.tar.gz # 解压 tar -zxvf libressl-3.0.2.tar.gz # 配置安装路径 mkdir /usr/local/libressl cd libressl-3.0.2 ./configure --prefix=/usr/local/libressl # 安装 make & make install # 创建软连接代替openssl mv /usr/bin/openssl /usr/bin/openssl.bak mv /usr/include/openssl /usr/include/openssl.bak ln -s /usr/local/libressl/bin/openssl /usr/bin/openssl ln -s /usr/local/libressl/include/openssl /usr/include/openssl echo /usr/local/libressl/lib >> /etc/ld.so.conf.d/libressl-3.0.2.conf ldconfig -v export LDFLAGS="-L/usr/local/libressl/lib" export CPPFLAGS="-I/usr/local/libressl/include" export PKG_CONFIG_PATH="/usr/local/libressl/lib/pkgconfig"
