python - 没有模块 _sha256 安装 cellProfiler

Question

我正在尝试在 Linux 上为开发人员安装 cellprofiler，但出现“没有名为 _sha256 的模块”错误。我查看了一些博客以找到解决方案，但没有任何效果，有人可以帮我解决这个问题吗？

这是我的配置:

Python 2.7.3 (default, Aug  1 2012, 05:16:07) 
[GCC 4.6.3] on linux2

Linux :

uname -m
i686

Distributor ID: Ubuntu
Description:    Ubuntu 12.04.2 LTS
Release:        12.04
Codename:       precise

这是我得到的错误:

local@pc-ellenberg23:~/Softwares/cellProfiler/CellProfiler$ make -f Makefile.CP2 PREFIX="${HOME}/usr/cp2"
All pre-checks executed successfully.

    import _sha256
ImportError: No module named _sha256

抱歉，如果错误看起来很愚蠢，我是处理 linux 安装错误消息的新手

非常感谢

您缺少 hashlib 模块的库依赖项。

在 Ubuntu 上，您需要安装 libsasl2-dev 和 libssl-dev 包，然后重新编译 (make -f Makefile.CP2 clean; make - f Makefile.CP2 PREFIX="${HOME}/usr/cp2"
) CellProfiler 依赖项。
