第一次尝试开草时出现以下错误

$ grass -text
ERROR: Unable to start GRASS GIS. You have the choice to:
 - Launch the graphical user interface with the '-gui' switch
     grass74 -gui
 - Launch with path to the location/mapset as an argument
     grass74 /path/to/location/mapset`
 - Create a location with '-c' and launch in its PERMANENT mapset
     grass74 -c EPSG:number /path/to/location
     grass74 -c geofile /path/to/location
 - Create manually the GISRC file (/home/nomon/.grass7/rc)
 - Use '--help' for further options
     grass74 --help

总体错误是：

$ grass

当我按照 gui 说明进行操作时：

$ grass74 -gui

我安装了 Grass-core、grass-gui、grass-dev、wx3.0-headers、wxsqlite3-3.0-dbg 和 wxcommon。

发生了什么？

发生的情况是用于运行草地的 python 解释器没有安装 wxPython 包。

为了解决它，您可以创建一个 python 环境（Conda 或 env），激活它并安装草所需的包（必不可少的是 wxpython 和 numpy）。

conda create -n grass_env python=3
conda activate grass_env
conda install wxpython
conda install numpy

然后，在这个环境中运行grass. 每次你想跑草，你都必须激活这个环境conda activate grass_env。
