Question

我正在尝试解压缩一个大的gzip文件（2GB）。如果我使用read（）函数，由于这么多数据，它会冻结我的计算机。所以，看看stackoverflow的另一个答案，我使用了逐行读取gzip文件的方法

inF = gzip.open(compressed_file_name, 'rb')
outF = open(outfilename, 'wb')
for line in inF:
    outF.write(line)
inF.close()
outF.close()

但是，在文件末尾，我收到以下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 12, in download_latest_file
  File "/usr/lib/python2.7/gzip.py", line 455, in readline
    c = self.read(readsize)
  File "/usr/lib/python2.7/gzip.py", line 261, in read
    self._read(readsize)
  File "/usr/lib/python2.7/gzip.py", line 308, in _read
    self._read_eof()
  File "/usr/lib/python2.7/gzip.py", line 347, in _read_eof
    hex(self.crc)))
IOError: CRC check failed 0x3b5a517c != 0x643d9301L

我的python版本是2.7.6

在python中解压缩gzip文件时出现CRC错误
