所以基本上，我只想加载与脚本在同一个文件夹中的国际象棋引擎

_, engine = await chess.engine.popen_uci('./engine')

这有什么问题？我以 root 用户身份运行脚本。

另外，如果我从 just 加载'engine'，它会说文件不存在。

UPT：收到此错误

 _, self.engine = await chess.engine.popen_uci(r'' + os.path.join(os.getcwd(), 'engine'))
  File "/usr/local/lib/python3.8/dist-packages/chess/engine.py", line 2642, in popen_uci
    transport, protocol = await UciProtocol.popen(command, setpgrp=setpgrp, **popen_args)
  File "/usr/local/lib/python3.8/dist-packages/chess/engine.py", line 1214, in popen
    return await asyncio.get_running_loop().subprocess_exec(cls, *command, **popen_args)  # type: ignore

如果我们检查文档，在播放部分中，您可以看到从根目录paths分配，如下所示：

r"C:\Users\xxxxx\Downloads\stockfish_14_win_x64\stockfish_14_win_x64_avx2.exe"
或 "/usr/bin/stockfish"。

虽然您要使用的引擎在您运行程序的同一文件夹中，但路径可以直接从安装Python的路径获取，我建议您_, engine = await chess.engine.popen_uci(r''+os.path.join(os.getcwd(), 'engine'))改用。

现在自己解决了这个问题。需要在引擎文件上执行这个

$ chmod 755 engine

所以基本上，它将文件权限更改为所需的权限。
