Error importing hashlib with python 2.7 but not with 2.6

The python2.7 package is dependent to the libssl1_0_0 package (openssl_1.0 runtime librairies).

I installed it, and added the /usr/local/ssl/lib directory in $LD_LIBRARY_PATH environnent variable.

And now it works perfectly! :)

same error for me. My case was a copied virtenv giving me this error on a new server. The default python was working.

I used

python2.7 -v -c "import hashlib" 2> output.txt

you should see something like this line below in your output.txt:

import hashlib # precompiled from hashlib.pycdlopen("/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 :

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,

ldd /path/to/Python-Library/_hashlibmodule.so

e.g

ldd /usr/local/lib/python2.7/_hashlibmodule.so

If you get output like below, that means you are missing necessary openssl libraries

    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)
