python - 属性错误 : 'module' object has no attribute 'TemporaryFile'

Question

我是 python 的新手。我正在学习标准库。

每当我运行下面的代码时，它总是引发 AttributeError...导入命令似乎有问题。

此外，我尝试在交互式解释器上运行它，它工作得很好。

示例代码

import tempfile
import os

#temp = tempfile.TemporaryFile()
temp = tempfile.mktemp()

print "tempfile","=>",temp

file = open(temp,"w+b")
file.write("*" * 1000)
file.seek(0)
print len(file.read()),"byte"
file.close()

try:
   os.remove(temp)
except OSError:
   pass

错误输出

Traceback (most recent call last):
  File "tempfile.py", line 1, in <module>
    import tempfile
  File "/home/zhkzyth/codeRep/pytest/tempfile.py", line 5, in <module>
    tempfile = tempfile.mktemp()
AttributeError: 'module' object has no attribute 'mktemp'
Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/apport_python_hook.py", line 66, in apport_excepthook
    from apport.fileutils import likely_packaged, get_recent_crashes
  File "/usr/lib/python2.7/dist-packages/apport/__init__.py", line 1, in <module>
    from apport.report import Report
  File "/usr/lib/python2.7/dist-packages/apport/report.py", line 12, in <module>
    import subprocess, tempfile, os.path, urllib, re, pwd, grp, os
  File "/home/zhkzyth/codeRep/pytest/tempfile.py", line 5, in <module>
    tempfile = tempfile.mktemp()
AttributeError: 'module' object has no attribute 'mktemp'

Original exception was:
Traceback (most recent call last):
  File "tempfile.py", line 1, in <module>
    import tempfile
  File "/home/zhkzyth/codeRep/pytest/tempfile.py", line 5, in <module>
    tempfile = tempfile.mktemp()
AttributeError: 'module' object has no attribute 'mktemp'

我的环境

• ubuntu12.04
• python2.7

您是否将自己的文件命名为 tempfile.py？如果是这样，请重命名它，删除所有 *.pyc 文件，然后重试。

PS:提供带有回溯的错误的实际文本会告诉我们这些事情。
