我在Solaris 10（x86）上。

到目前为止，我一直在使用python2.6。今天，我安装了python2.7，并且在2.7而不是2.6上导入hashlib时发生奇怪的错误：

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"
ERROR:root:code for hash md5 was not found.

我不明白为什么会出现此错误，因为我正在 同一台机器上 尝试导入。

在此先感谢您的帮助！
