Question

我有一个python-3.6.5代码，它使用Sub InsertMissingDates() Dim i As Long Dim RowCount As Long Dim WhichCol As String i = 4 WhichCol = "D" Do If Cells(i, WhichCol) + 1 < Cells(i + 1, WhichCol) Then Rows(i + 1).Insert Cells(i + 1, WhichCol) = Cells(i, WhichCol) + 1 End If If (Cells(i + 1, WhichCol) = "") Then Cells(i + 1, WhichCol) = Cells(i, WhichCol) + 1 End If i = i + 1 Loop Until Cells(i, WhichCol).Value >= DateSerial(2016, 1, 30) End Sub复制文件。使用它时出现权限错误，并且无法跟踪错误源。以下是适当的代码段：

shutil.copy2()

我收到这个有趣的权限错误。我很困惑b / c该文件没有任何有趣的权限。例如

>>> genome='HCC2A1.bin.22.fa'
>>> output_folder='/gpfs0/home/group/user/Scratch/somedir/output_directory3/dereplicated_genomes/'
>>> loc='/gpfs0/home/group/user/Scratch/somedir/HCC2A1.bin.22.fa'
>>> shutil.copy2(loc, "{0}{1}".format(output_folder,genome))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/python/3.6.5/lib/python3.6/shutil.py", line 258, in copy2
    copystat(src, dst, follow_symlinks=follow_symlinks)
  File "/opt/python/3.6.5/lib/python3.6/shutil.py", line 225, in copystat
    _copyxattr(src, dst, follow_symlinks=follow)
  File "/opt/python/3.6.5/lib/python3.6/shutil.py", line 165, in _copyxattr
    os.setxattr(dst, name, value, follow_symlinks=follow_symlinks)
PermissionError: [Errno 13] Permission denied: '/gpfs0/home/group/user/Scratch/somedir/output_directory3/dereplicated_genomes/HCC2A1.bin.22.fa'

此外，实际上是~$ ls -l /gpfs0/home/group/user/Scratch/somedir/HCC2A1.bin.22.fa -rwxrwxrwx. 1 user group 4850851 Aug 29 13:21 /gpfs0/home/group/user/Scratch/somedir/HCC2A1.bin.22.fa试图创建（并且据说失败了）的文件，该文件似乎具有适当的权限。例如

shutil.copy2

我试图在系统级模块内设置断点（以进行进一步研究），但无济于事。例如。（从上面继续python解释器代码...）

~$ ls -l /gpfs0/home/group/user/Scratch/somedir/output_directory3/dereplicated_genomes/
total 4768
-rwxrwxrwx. 1 user group 4850851 Aug 29 13:21 HCC2A1.bin.22.fa

问题

为什么不能在系统级HCC2A1.bin.22.fa上设置断点？

了解shutil.copy2 PermissionError [Errno 13]
