我在 Solaris 10 (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上没有：

蟒蛇2.6：

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

蟒蛇 2.7：

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。

在此先感谢您的帮助！

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

我安装了它，并在环境变量中添加了/usr/local/ssl/lib目录。$LD_LIBRARY_PATH

现在它完美地工作了！:)

对我来说同样的错误。我的案例是副本virtenv，在新服务器上给了我这个错误。默认的python正在工作。

我用了

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

你应该在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
...

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

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

如果你得到如下输出，这意味着你缺少必要的 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)

我知道您使用的是 Solaris，但我已经按照这些说明安装了旧的 libssl1.0-dev，它可以在 Ubuntu 20.04 上运行。

编辑文件/etc/apt/sources.list并将这一行添加到它的末尾。

deb http://security.ubuntu.com/ubuntu bionic-security main

之后运行：

sudo apt update && apt-cache policy libssl1.0-dev

最后，

sudo apt-get install libssl1.0-dev
