Error importing hashlib with python 2.7 but not with 2.6
提问by SuperPython
I'm on Solaris 10 (x86).
我在 Solaris 10 (x86) 上。
Until now, I was using python2.6. Today, I installed python2.7 and I have a weird error occuring when importing hashlib on 2.7, but not on 2.6:
到现在为止，我使用的是python2.6。今天，我安装了 python2.7，在 2.7 上导入 hashlib 时发生了一个奇怪的错误，但在 2.6 上没有：

I don't understand why I have this error since I'm trying the import ON THE SAME MACHINE.
我不明白为什么会出现此错误，因为我正在尝试在同一台机器上导入。
Thanks in advance for your help!
在此先感谢您的帮助！

The python2.7 package is dependent to the libssl1_0_0package (openssl_1.0 runtime librairies).
python2.7 包依赖于libssl1_0_0包（openssl_1.0 运行时库）。
I installed it, and added the /usr/local/ssl/libdirectory in $LD_LIBRARY_PATHenvironnent variable.
我安装了它，并/usr/local/ssl/lib在$LD_LIBRARY_PATH环境变量中添加了目录。
And now it works perfectly! :)
现在它完美无缺！:)

same error for me. My case was a copied virtenvgiving me this error on a new server. The default python was working.
对我来说同样的错误。我的情况是一个副本virtenv，在新服务器上给了我这个错误。默认的python 正在工作。
I used
我用了
python2.7 -v -c "import hashlib" 2> output.txt
you should see something like this line below in your output.txt:
你应该在你的下面看到类似这一行的内容output.txt：
import hashlib # precompiled from hashlib.pyc
dlopen("/path/to/virtenv/lib/python2.7/lib-dynload/_hashlib.so", 2);
ldd /path/to/virtenv/lib/python2.7/lib-dynload/_hashlib.so
...
libssl.so.0.9.8 => not found
libcrypto.so.0.9.8 => not found
...
So what I did is simply :
所以我所做的很简单：
cp /usr/lib/python2.7/lib-dynload/_hashlib.so /*path-to-virtenv*/manager/lib/python2.7/lib-dynload/_hashlib.so

You can use below command and check which libraries are missing,
您可以使用以下命令并检查缺少哪些库，
ldd /path/to/Python-Library/_hashlibmodule.so
e.g
例如
ldd /usr/local/lib/python2.7/_hashlibmodule.so
If you get output like below, that means you are missing necessary openssl libraries
如果您得到如下输出，则意味着您缺少必要的 openssl 库
linux-vdso.so.1 => (0x00007fffd6f6a000)
libssl.so.6 => not found
libcrypto.so.6 => not found
libpython2.7.so.1.0 => /lib64/libpython2.7.so.1.0 (0x00007ffb18b54000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007ffb18937000)
libc.so.6 => /lib64/libc.so.6 (0x00007ffb185a2000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007ffb1839e000)
libutil.so.1 => /lib64/libutil.so.1 (0x00007ffb1819b000)
libm.so.6 => /lib64/libm.so.6 (0x00007ffb17f16000)
/lib64/ld-linux-x86-64.so.2 (0x0000003e0a000000)
