我在Solaris 10(x86)上.

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:

Python 2.6:

root@myserver [PROD] # python2.6 -c "import hashlib"
root@myserver [PROD] #

Python 2.7:

root@myserver [PROD] # python2.7 -c "import hashlib"

我不明白为什么我有这个错误,因为我正在尝试导入相同的机器.

在此先感谢您的帮助!

对我来说同样的错误.我的情况是复制virtenv在新服务器上给我这个错误.默认的python正在运行.

我用了

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

你应该看到下面的这一行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
...

所以我所做的只是:

cp /usr/lib/python2.7/lib-dynload/_hashlib.so /*path-to-virtenv*/manager/lib/python2.7/lib-dynload/_hashlib.so

forsoz_627

python2.7包依赖于libssl1_0_0包(openssl_1.0运行时库).

我安装了它,并/usr/local/ssl/lib在$LD_LIBRARY_PATHenvironnent变量中添加了目录.

现在它完美无缺!:)

您可以使用以下命令并检查缺少哪些库,

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

例如

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

如果得到如下所示的输出,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)
