注:本博文主要为转载后根据本人情况再加工 1 问题: python3.7.2安装遇到如下ssl问题 >>> import ssl Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python3.7/ssl.py", line 98, in import _ssl # if we can't import it, let the error propagate ModuleNotFoundError: No module named '_ssl' 2 解决办法 2.1安装依赖 yum groupinstall development 2.2 安装libressl代替openssl-devel 2.2.1 原因 由于系统的openssl是1.0.1的版本,对于python3.7太老了,需要更新为openssl1.0.2或者libressl2.64(不含)以后的版本,所以这里从libressl官网下载libressl源码,编译生成库文件代替系统的openssl1.0.1 2.2.2 安装libressl 下载libressl-2.8.0 ./config –prefix=/usr/local/libressl make make intall 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 2.2.3 加载lib cd /etc/ld.so.conf.d 新建文件 vim libressl-2.8.0.conf #将以下行加入文件,并保存 /usr/local/libressl/lib ldconfig -v #重新加载库文件 2.3安装python3.7 从官网下载python3.7的源码, 解压后进入Python-3.7.0 编译前需要设置环境变量(重要) export LDFLAGS="-L/usr/local/libressl/lib" export CPPFLAGS="-I/usr/local/libressl/include" export PKG_CONFIG_PATH="/usr/local/libressl/lib/pkgconfig" ./configure –prefix=/usr/local/python3 –enable-shared CFLAGS=-fPIC 运行后会出现一堆信息: 注意最后的ssl检查,如下图所示: 2.4 处理异常 运行python3.7命令遇到:libpython3.7m.so.1.0: cannot open shared object file: No such file or d echo /usr/local/python3.7/lib > /etc/ld.so.conf.d/python3.7.conf ldconfig -v 2.4 验证 linux下gunicorn+flask项目的部署 |
