我已成功在本地计算机上安装Python 3.4和Python 3.6,但无法安装包pip3.
执行时pip3 install <package>,我收到以下与SSL相关的错误:
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting <package>
Could not fetch URL https://pypi.python.org/simple/<package>/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping
Could not find a version that satisfies the requirement <package> (from versions: )
No matching distribution found for <package>
如何修复我的Python3.x安装,以便我可以安装包pip install …
我需要在RHEL上安装几个Python模块,我没有root访问权限.至少有一个模块也需要访问Python.h.
在这种情况下,我发现最好的方法是安装python及其依赖项~/local.它通常只是工作,但这次Python无法构建SSL模块(请参阅下面的详细信息).这是我正在做的事情的痕迹.
所以我下载了python 6源码然后关闭了我:
./configure --prefix=/home/fds/rms/local
make >& make.log
对日志的检查显示ssl模块尚未编译,但没有提及原因(make或configure中没有其他ssl出现):
Failed to find the necessary bits to build these modules:
_bsddb _curses _curses_panel
_hashlib _sqlite3 _ssl <----------
所以我想,python根本找不到任何ssl库(这很奇怪,但是嘿......).所以我下载openssl-0.9.8r和
./config --prefix=/home/fds/rms/local shared
make
make install
现在回到Python,我./configure并重新制作.它失败了,但这一次有所不同:
Failed to build these modules:
_hashlib _ssl
仔细检查日志文件可以发现:
gcc -pthread -shared build/temp.linux-x86_64-2.6/home/fds/rms/installers/Python-2.6.6/Modules/_ssl.o -L/home/fds/rms/local/lib -L/usr/local/lib -lssl -lcrypto -o build/lib.linux-x86_64-2.6/_ssl.so
*** WARNING: renaming "_ssl" since importing it failed: libssl.so.0.9.8: cannot open shared object file: No such file or directory
所以现在它正在拿起图书馆,但不是很正确(文件应该在哪里):
$ find /home/fds/rms/local …从源代码构建Python 3.7会遇到以下错误:
Failed to build these modules:
_hashlib _ssl
Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381
我从其他stackoverflow问题尝试了很多变通方法,但它不起作用.我从源代码构建最新的OpenSSL和LibreSSL.OpenSSL路径是:"/ usr/local/ssl",版本为OpenSSL 1.0.2p.
./configure --with-openssl=/usr/local/ssl/
(./configure CPPFLAGS="-I/usr/local/ssl/include" LDFLAGS="-L/usr/local/ssl/lib")
make
make altinstall
我的系统:Ubuntu 12.04.5 LTS
有任何想法吗？
