错误:
File "/home/alien/cncell/core/animator.py", line 413, in create_animation_from_data
pygame.image.save(screen, image_fp)
pygame.error: SavePNG: could not create png write struct
可能提示A:我现在在Ubuntu上。在Windows上运行相同的脚本时,我没有遇到此问题。
可能的提示B:首次调用pygame.image.save
时,libpng
会产生以下警告:
libpng警告:使用libpng-1.2.51构建的应用程序,但以1.6.17
运行
我该怎么做才能解决这个问题?
我尝试过的一些事情:
1)我可以加载PNG吗?是
2) python -m pygame.tests
的结果:

Ran 708 tests in 28.894s
FAILED (failures=2, errors=6)
这些测试的结果让我认为问题不太可能是由于我的代码从Windows移植到Ubuntu所特有的问题(例如,我试图尽可能地修复路径名等,以及pygame
测试应该是独立于平台的,但仍然失败?)。
答案 0 :(得分:0)
此问题是由于I installed my Python stack using Anaconda引起的,但后来是installed pygame
using the build+install instructions for Ubuntu on pygame
's documentation page。
这导致libpng
的{{1}}库存在冲突,我认为,某处,某种程度上。
无论如何,这个问题已经解决了:
1)删除pygame(因为我使用pip
安装pygame的说明,pip uninstall pygame
做了伎俩)
2)安装pygame
using a build some kind soul had contributed to the conda
repositories
然后,运行python -m pygame.tests
报告没有错误,除了:

对于这个问题,我对此感到满意。
