Satyam，首先，你的问题确实需要重新格式化，当在这里发布这样的问题时，会让它看起来质量不好，它的呈现方式不适合帮助其他人理解问题。
通常，您会遇到库问题，这是因为您没有/usr/lib/x86_64-linux-gnu/libpng12.so.0，这是真的，您可能只有/usr/lib/x66_64-linux-gnu/libping12.so.0.54.0
为了克服这个问题，只需创建一个名为/usr/lib/x86_64-linux-gnu/libpng12.so.0的符号链接，指向/usr/lib/x66_64-linux-gnu/libpmg12.so.0.54.0
文件夹应该包含2个文件，如以下2:
/usr/lib/x86_64-linux-gnu/libpng12.so.0 (symlink)
/usr/lib/x86_64-linux-gnu/libpng12.so.0.54.0
