Python逐行处理大文件时出现内存错误

with open('file.txt', 'r') as file:
    for line in file:
        # 处理每一行的内容
        pass

chunk_size = 1024  # 每次读取的字节数
with open('file.txt', 'r') as file:
    while True:
        chunk = file.read(chunk_size)
        if not chunk:
            break
        # 处理每一块的内容
        pass

def read_lines(file_path):
    with open(file_path, 'r') as file:
        for line in file:
            yield line

for line in read_lines('file.txt'):
    # 处理每一行的内容
    pass
