在python 2.7中导入hashlib时出错，但在2.6中不是
提问于 2013-12-05 19:53:36
我在Solaris10 (x86)上。
到目前为止，我使用的是python2.6。今天，我安装了python2.7，在2.7上导入hashlib时出现了一个奇怪的错误，但在2.6上却没有：
Python 2.6：
root@myserver [PROD] # python2.6 -c "import hashlib"
root@myserver [PROD] # Python 2.7：

ValueError: unsupported hash type sha512我不明白为什么会出现这个错误，因为我在同一台机器上尝试导入。
提前感谢您的帮助！

Openssl_1.0 2.7包依赖于python2.7包(python2.7运行时库)。
我安装了它，并在$LD_LIBRARY_PATH环境变量中添加了/usr/local/ssl/lib目录。
现在它完美地工作了！:)

我也犯了同样的错误。我的案例是一个复制的virtenv，在一个新的服务器上给了我这个错误。默认的python运行正常。
我用过
python2.7 -v -c "import hashlib" 2> output.txt您应该会在output.txt中看到类似下面这一行的内容
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
...所以我所做的很简单：
cp /usr/lib/python2.7/lib-dynload/_hashlib.so /*path-to-virtenv*/manager/lib/python2.7/lib-dynload/_hashlib.soStack Overflow用户

您可以使用下面的命令并检查缺少哪些库，
ldd /path/to/Python-Library/_hashlibmodule.soe.g
ldd /usr/local/lib/python2.7/_hashlibmodule.so如果您得到如下所示的输出，这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)
