建立android环境时，运行以下命令：
$ ./walkthrough.sh ALL
提示以下错误
File "/home/dongtz/work/android/Gen3_Android_v10_2.0/RENESAS_RCH3M3M3N_Android_10_ReleaseNote_2020_09E/mydroid/.repo/repo/main.py", line 79
file=sys.stderr)
^
SyntaxError: invalid syntax
原因：
...mydroid/.repo/repo$ vim main.py
发现，需要python 3环境
# python-3.6 is in Ubuntu Bionic.
MIN_PYTHON_VERSION_SOFT = (3, 6)
MIN_PYTHON_VERSION_HARD = (3, 5)
if sys.version_info.major < 3:
print('repo: error: Python 2 is no longer supported; '
'Please upgrade to Python {}.{}+.'.format(*MIN_PYTHON_VERSION_SOFT),
file=sys.stderr)
sys.exit(1)
else:
检查当前python环境：
$ python2 --version
$ python3 --version
Python 3.7.8
$ python --version
Python 2.7.12
$ echo alias python=python3 >> ~/.bashrc #更改当前python环境
$ source ~/.bashrc
$ python --version # 确认一下
Python 3.7.8
重新设置repo
$ curl https://storage.googleapis.com/git-repo-downloads/repo-1 > repo
$ chmod +x repo
$ export PATH=$(pwd):${PATH}
删除mydroid/后，重新按照手册进行操作。
