今天刚刚下载了Hi3861的代码code1.0，按照环境要求配置好，然后执行构建的时候报错：ImportError: cannot import name 'common_env' from 'scripts'

具体如下

Traceback (most recent call last):

  File "/home/peter/.local/lib/python3.7/site-packages/SCons/Script/Main.py", line 1391, in main

    _exec_main(parser, values)

During handling of the above exception, another exception occurred:

打开构建脚本一看，原来是找不到commen_env.py模块，该python文件放在 code/vendor/hisi/hi3861/hi3861/build/scripts/ 目录下，构建脚本是 vendor/hisi/hi3861/hi3861/SConstruct，打开发现问题：

sys.path.append(os.path.join(os.getcwd(), 'build'))

print('------------------',os.getcwd())

print(sys.path)

from scripts import common_env

from scripts import scons_utils

from scripts import scons_app1.

代码中已经把 build目录添加到sys路径里面了，但是由于scripts目录太过常见，添加的路径太靠后，导致python找到了错误的scripts文件夹（/root/anaconda3/lib/python3.7/site-packages/scripts），解决方法很简单：把append修改为insert即可：

sys.path.insert(0,os.path.join(os.getcwd(), 'build'))

print('------------------',os.getcwd())

print(sys.path)

from scripts import common_env

from scripts import scons_utils
