Question

我安装了scons 2.3.2并使用了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:

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

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？

问题（来自追踪的底部）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

无法运行scons获取导入错误
