python – 无法运行scons获取导入错误

我已经安装了scons 2.3.2并且有python 2.4.

当我运行scons时,我看到以下错误：

scons
Import failed. Unable to find SCons files in:

我做了一个发现,发现SCons存在于/usr/lib / scons中.我不确定为什么scons无法接收它.

我错过了什么？

解决方法:

问题(从追踪的底部)是语法错误：

    p = self.stack[-1] if self.stack else self.default_table
                        ^
SyntaxError: invalid syntax

这是因为您运行的是不支持条件表达式的Python版本：

2.5中添加了对此语法的支持,请参阅the docs
