我找不到一种可以在Python中使用的方式来阅读Minecraft世界文件
我在互联网上找过，但是没有找到教程，只有少数几个库声称他们可以做到这一点，但实际上从来没有工作过

from nbt import *
nbtfile = nbt.NBTFile("r.0.0.mca",'rb')

我期望这个工作，但相反，我得到了关于文件没有被压缩或类似的错误
完整错误：

使用砧座解析器。（使用pip install anvil-parser安装）
阅读

import anvil

region = anvil.Region.from_file('r.0.0.mca')

# You can also provide the region file name instead of the object
chunk = anvil.Chunk.from_region(region, 0, 0)

# If `section` is not provided, will get it from the y coords
# and assume it's global
block = chunk.get_block(0, 0, 0)

print(block) # <Block(minecraft:air)>
print(block.id) # air
print(block.properties) # {}

根据this page，.mca文件并不完全是NBT文件。它以一个8KiB的头文件开始，其中包括区域文件本身中块的偏移量和这些块的最后更新时间戳。我建议您查看the offical announcement和this page以了解更多信息。
