我遇到了一些 CLIPSpy 代码的问题。我已将问题缩小到 CLIPS_CONSTRUCTS.encode() 或 environment.load(constructs_file.name) 的编码方法。我试图捕捉的目标是在油温高于 32 且油压高于 0 时触发规则。我已附加正在使用的 SampleData.csv。这是我论文研究的一部分，我想感谢所有帮助我的人！

  • 操作系统和版本：Windows 10 64 位
  • Python版本：3.7.2
  • 库和版本（通过 pip 列表）
    cffi 1.11.5
    clipspy 0.3.0
    pip 18.1
    pycparser 2.19
    setuptools 40.6.2

这是此处NamedTemporaryFile记录的 Windows的限制。

您可以使用mkstemp完成后自己删除的常规文件或常规文件来解决它。

constructs_file, constructs_file_name = mkstemp()
constructs_file.write(CLIPS_CONSTRUCTS.encode())
constructs_file.close()

environment.load(constructs_file_name)
os.remove(constructs_file_name)

使用以下代码让它工作：

constructs_file, constructs_file_name = mkstemp()
file = open(constructs_file, 'wb')
file.write(CLIPS_CONSTRUCTS.encode())
file.close()

environment.load(constructs_file_name)
os.remove(constructs_file_name)

由于某种原因，代码在文件描述符方面存在问题，因为它没有写入方法。把代码改了一点，砰！有用！
