无法获得python包含用于GalSim的路径python可执行文件

Question

我试图通过运行GalSim在Ubuntu14.04上安装(更新)本地版本的SCons软件。我有所有的依赖项(boost，TMV等)安装并使用了很长一段时间了。我用Python2.7。但是现在，当我从终端运行scons时，我会得到以下错误：

scons: Reading SConscript files ...
SCons is version 2.3.0 using python version 2.7.6
Python is from /usr/include/python
Using the following (non-default) scons options:
PYPREFIX = /usr/lib/python2.7/dist-packages/
TMV_DIR = /media/arunkannawadi/Acads_CMU/Cosmology/WFIRST_Project/tmv0.72/
These can be edited directly in the file gs_scons.conf.
Type scons -h for a full list of available options.

Please fix the above error(s) and rerun scons.
Note: you may want to look through the file INSTALL.md for advice.
Also, if you are having trouble, please check the INSTALL FAQ at

which python输出为/usr/bin/python，python --version输出为Python 2.7.6。

Answer 1

经过进一步研究，这个问题并不是关于GalSim本身，而是指出了一个奇怪的后来的Ubuntu版本。

在检查了失败安装的config.log文件(不在这里发布)之后，很明显，安装的测试是通过的，但是在解析这些测试的输出时失败了。错误信息是

sh: 1:语法错误:错误fd号

搜索给我指出了关于错误消息的另一个问题：sh: Syntax error: Bad fd number，它指出在Ubuntu11.x / bin /sh中链接到/bin/dash，而不是bin bash。因此，解决GalSim安装这个明显问题的方法是使用页面上的解决方案将/bin/sh正确链接到bash。
