这个错误是由于没有权限写入文件导致的。你可以尝试以下解决方案：

1. 确保你有足够的权限来写入所指定的文件路径。你可以检查文件的权限设置，并确保你有写入权限。

2. 如果你是在一个受限制的环境下运行，比如在某些服务器上，你可能需要联系管理员或者使用管理员权限来运行程序。

3. 如果你在运行程序之前已经打开了同名的文件，尝试关闭该文件并重新运行程序。

4. 如果你在使用其他程序或者进程访问该文件，确保没有其他程序正在使用该文件。可以尝试关闭这些程序或者等待它们完成操作后再运行程序。

如果以上解决方案都无效，可能需要进一步检查代码和环境设置来定位问题。

这个错误通常是由于在使用pickle模块将对象序列化时，对象中存在不能被序列化的属性或方法所导致的。有可能是在使用多进程库时，进程间传递了一个不能被序列化的_io.TextIOWrapper对象，导致了这个错误。你可以尝试将输出路径参数output_path改为一个字符串类型而非一个文件对象类型。另外，你可以尝试将输出文件的写入操作放在主进程中，而非在子进程中进行。这样可以避免在子进程中对文件对象进行pickle序列化。以下是一个可能的解决方案：

def worker_process(input_queue, output_queue, output_path):
    # create output file in main process
    with open(output_path, 'w', encoding='utf-8') as output_file:
        while True:
            data = input_queue.get()
            if data is None:
                break
            # process data
            # ...
            output = process_data(data)
            # put result into output queue
            output_queue.put(output)
            # write result to output file
            output_file.write(output)

def process_dump(input_file, templates, output_path, file_size, process_count):
    # create input queue
    input_queue = Queue(maxsize=process_count)
    # create output queue
    output_queue = Queue(maxsize=process_count)
    # spawn processes
    processes = []
    for i in range(process_count):
        p = Process(target=worker_process, args=(input_queue, output_queue, output_path))
        processes.append(p)
        p.start()
    # read input file and put data into input queue
    with open(input_file, 'r', encoding='utf-8') as f:
        for line in f:
            input_queue.put(line)
    # stop worker processes
    for i in range(process_count):
        input_queue.put(None)
    for p in processes:
        p.join()
    # collect results from output queue and write to output file
    with open(output_path, 'w', encoding='utf-8') as output_file:
        while not output_queue.empty():
            output = output_queue.get()
            output_file.write(output)

在这个改进的代码中，我们将输出路径参数output_path改为一个字符串类型，并在主进程中打开输出文件，将输出文件的写入操作放在主进程中进行，避免在子进程中对文件对象进行pickle序列化。

这个报错是因为在您的代码中使用了`fcntl`模块来进行文件锁定，但是在您的环境中该模块没有`LOCK_EX`属性。这可能是因为您的操作系统不支持`fcntl`模块或者您的Python版本不兼容`fcntl`模块。

您可以尝试使用其他方式来实现文件锁定，例如使用`msvcrt`模块（仅适用于Windows系统）或者使用`fcntl`模块的其他属性（例如`LOCK_SH`、`LOCK_NB`等）。

另外，请确保您的Python版本和操作系统环境与代码中使用的模块和属性兼容。

如果您需要更具体的帮助，请提供您使用的Python版本以及操作系统信息。
