导入时出现问题草.script进入PyD

Question

我尝试在Eclipse中编写grass脚本，并按照this页面中概述的说明进行操作。当我尝试导入时，我想我已经配置好了一切草.script我得到以下信息：

Traceback (most recent call last):
  File "/home/nesic/Desktop/grass_dev/Simulacije/test.py", line 6, in <module>
    import grass.script as grass
  File "/usr/lib/grass64/etc/python/grass/script/__init__.py", line 1, in <module>
    from core   import *
  File "/usr/lib/grass64/etc/python/grass/script/core.py", line 38, in <module>
    gettext.install('grasslibs', os.path.join(os.getenv("GISBASE"), 'locale'), unicode=True)
  File "/usr/local/lib/python2.6/posixpath.py", line 67, in join
    elif path == '' or path.endswith('/'):
AttributeError: 'NoneType' object has no attribute 'endswith'

我做错什么了？在

Answer 1

os.getenv("GISBASE")很可能返回None，因为没有设置envoriment变量GISBASE。这就导致了AttributeError: 'NoneType' object has no attribute 'endswith'你看到的。在

尝试根据http://grass.osgeo.org/grass70/manuals/variables.html设置GISBASE：

GISBASE

directory where GRASS lives. This is set automatically by the startup script.

（顺便说一句，如果你还不知道，还有gis.stackexchange.org）
