scons“导入不存在的变量” env：如何解决？

Question

I'm hoping that all SConscript could share the environment definition from SConstruct, like this: 我希望所有SConscript都可以共享SConstruct中的环境定义，如下所示：

cat ./SConstruct 目录./SConstruct

import os,sys
env = Environment(ENV = {'PATH' : os.environ['PATH']})
env.SConscript(dirs=['mydir'])

Then under ./mydir 然后在./mydir下

cat ./SConscript 猫./SConscript

Import('env')
env = env.Clone()

I try to run it: 我尝试运行它：

scons
scons: Reading SConscript files ...

scons: *** Import of non-existent variable ''env''
File "/home/john/mydir/SConscript", line 1, in <module>

So why scons failed to "Import env", is my syntax wrong? 那么，为什么scons无法“导入环境”，我的语法错误吗？ Thanks. 谢谢。

As @dirkbaechle said. 正如@dirkbaechle所说。 Change your SConstruct to: 将您的SConstruct更改为：

import os,sys
env = Environment(ENV = {'PATH' : os.environ['PATH']})
env.SConscript(dirs=['mydir'], exports='env')
