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,并获得一个名为"_sha256"的"无模块"错误.我在几个博客上找到了解决方案,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,如果错误似乎很愚蠢,我是新的处理Linux安装上的错误消息

非常感谢你

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.
