the ssl module in Python is not available错误解决
在使用pip安装pymongo的过程中报错,提示如下:
1 $ pip3 install pymongo 2 pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. 3 Collecting pymongo 4 Could not fetch URL https://pypi.python.org/simple/pymongo/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping 5 Could not find a version that satisfies the requirement pymongo (from versions: ) 6 No matching distribution found for pymongo
这是由于缺少ssl模块,进入python中验证。
$ python Python 3.7.0a3 (default, Jan 10 2018, 14:36:35) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import ssl Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.7/ssl.py", line 100, in <module> import _ssl # if we can't import it, let the error propagate ModuleNotFoundError: No module named '_ssl' >>>
原因找到:缺少openssl-devel包
$ rpm -qa | grep openssl openssl-1.0.2k-8.el7.x86_64 xmlsec1-openssl-1.2.20-7.el7_4.x86_64 openssl-libs-1.0.2k-8.el7.x86_64
解决方法:
1、安装openssl-devel包
$ sudo yum install -y openssl-devel
2、重新编译安装pyhton
修改Setup配置
$ vi Modules/Setup 找到 # Socket module helper for socket(2) #_socket socketmodule.c # Socket module helper for SSL support; you must comment out the other # socket line above, and possibly edit the SSL variable: #SSL=/usr/local/ssl #_ssl _ssl.c \ # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ # -L$(SSL)/lib -lssl -lcrypto 改为 # Socket module helper for socket(2) _socket socketmodule.c # Socket module helper for SSL support; you must comment out the other # socket line above, and possibly edit the SSL variable: #SSL=/usr/local/ssl _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto
编译安装
./configure && sudo make && sudo make install
