安装hashlib失败，Python 3，Debian

29

软件安装失败。希望得到帮助解决此问题。

我认为这个错误可能是依赖性错误。

        ----------------------------------------

我正在使用这个库为文件生成哈希值，因此欢迎提供其他替代方案。

错误是由于Python 2语法raise ValueError, "unsupported hash type"引起的，在Python 3中应写为raise ValueError("unsupported hash type")。您正在发出什么命令来安装hashlib？ - jmd_dk

pip3安装hashlib :) - dipl0

根据pypi的说明，hashlib适用于Python 2.4及以下版本。Python 2.5及以上版本已经包含了hashlib。您可以尝试导入hashlib以验证。 - jmd_dk

hashlib 模块已默认安装（我认为从 Python 2.6 开始）。您正在尝试安装一个为了向前兼容旧版本 Python 而创建的其余版本。

只需执行 import hashlib 并开始使用它。

您可以通过在 https://pypi.python.org/pypi 进行搜索来查找有关软件包的信息。
