/usr/lib/python2.7/site-packages/pymysql/cursors.py:166:

这是一个Python 2.7的警告，提示你的程序中使用了pymysql库的游标（cursor）模块。这个警告通常是因为Python 2.7的某些版本中，pymysql库的游标模块存在一些已知的问题，可能会导致程序出现一些奇怪的行为或错误。建议升级到Python 3.x版本，并使用更稳定的版本的pymysql库来避免这个问题。

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages

这个命令是将你安装的 Python 库路径添加到系统环境变量 PYTHONPATH 中，以便 Python 解释器能够找到这些库。

具体来说，这个命令将 /usr/local/lib/python2.7/site-packages 这个目录加入到 PYTHONPATH 中。如果你在这个目录下安装了一些 Python 库，那么这些库就可以被 Python 解释器找到并使用了。

这个错误是由于使用的是 Python 2.7 而不是 Python 3.x，导致在执行 c_client.py 脚本时出现了错误。您需要在命令行中使用正确的 Python 版本来运行该脚本。您可以尝试使用以下命令来运行该脚本：

python3 c_client.py -p /usr/lib/python3.8/site-packages /usr/share/xcb/xproto.xml

您需要将所有的命令都替换为类似的命令，以正确运行该脚本。
