近期在进行开发的时候遇到了这个问题，查找了半天没有找到一个完整的靠谱解决办法，由于是新手不是很熟练，思考了几天后，发现了问题所在python版本的问题。

第一步 输入一下内容查看python是否已经设置好软连接

进行之前先查看python安装路径

which python  #查看python安装路径

查看后进行一下操作

cd /usr/bin  #进如这个目录
ll python   #查看是否设置软连接
ll python3  #查看是否设置软连接

若没有则进行配置：

sudo rm /usr/bin/python   #有需要删除则执行这条语句
 
sudo ln -s /usr/bin/python3.？？？ /usr/bin/python   #注意查看自己安装的版本是多少自行替换   
 

第二步：

进入DevEco/Projects/OpenHarmony-v3.2-Release/prebuilts/python/linux-x86/3.9.2/bin

查看genconfig 文件的python路径是否正确

使用在DevEco/Projects/OpenHarmony-v3.2-Release/prebuilts/python/linux-x86/3.9.2/bin路径下使用vim编辑器查看 genconfig文件

vim genconfig 

打开后应该是如下代码

#!/bin/sh
   '''exec' /root/data/harmony/release_code/2023-04-09/OpenHarmony-v3.2-Release/OpenHarmony/prebuilts/python/linux-x86/3.9.2/bin/python3.9 "$0" "$@"
 
 
' '''
# -*- coding: utf-8 -*-
import re
import sys
from genconfig import main
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())
~                                                                                                                                                                                                                 
~                                                                                    

由于我安装的是python3.8的版本但是这里显示的是3.9，且路劲为/root/data/harmony/release_code/2023-04-09/OpenHarmony-v3.2-Release/OpenHarmony/prebuilts/python/linux-x86/3.9.2/bin。我们需要修改这个，python路径，讲起修改为本地的python路径，若不知道本地路径则使用上述查看方式。

修改如下（将默认路径替换为：''/usr/bin/python“）：

#!/bin/sh
'''exec' /usr/bin/python "$0" "$@"
' '''
# -*- coding: utf-8 -*-
import re
import sys
from genconfig import main
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())
~                                                                                                                                                                                                                 
~                                                                                    

注意这里路径这一行需要注意格式（在标准的Python代码中，一般使用四个空格符作为一个缩进层级）（别问我为什么发现了这个问题，因为我是直接提行随便敲了一个空格后发现代码还是有错）。

然后我们继续如用vscode里面的DevEco Device Tool里的build进行编译就能正确编译了。

我是通过以上方式解决的这个问题，大伙遇到这个问题可以试一试，不行的话可以去

Laval社区  提问，请教专业人员，希望我的贴子能帮到你！

另外说一下我在用这个板子进行烧录的小tip，之前烧录一直不行不知道什么原因，最后才发现是线没有接完整。一共要接三根线。我都没有按那个启动键他就自动烧录好了，只需要插拔电源线即可。

最后希望大家学习顺利！
