我不确定如何最好地解决或查询此问题。我有一个简单的程序，它使用了fs.sshfs依赖于的paramiko模块cryptogaphy.utils。来自我virtualenv的 withpython版本3.5.2。

(venv) $ cat tump.py
from fs.sshfs import SSHFS

remote = SSHFS('rushmore')
print(*remote.listdir('.'), sep='\n')

我的环境安装了以下模块。

(venv) $ pip freeze
appdirs==1.4.3
asn1crypto==0.24.0
bcrypt==3.1.4
cffi==1.11.5
cryptography==2.2.2
fs==2.0.21
fs.sshfs==0.8.0
idna==2.6
paramiko==2.4.1
pkg-resources==0.0.0
pyasn1==0.4.2
pycparser==2.18
PyNaCl==1.2.1
pytz==2018.4
six==1.11.0
typing==3.6.4

当我直接在文件上调用 python 时，我收到了一个AttributeError反对getargspec.

(venv) $ python tump.py
Traceback (most recent call last):
  File "tump.py", line 1, in <module>
    from fs.sshfs import SSHFS
  File "/mnt/max/home/robinsph/git/HCPVaTT/venv/lib/python3.5/site-packages/fs/sshfs/__init__.py", line 7, in <module>

    signature = inspect.getargspec
AttributeError: module 'inspect' has no attribute 'getargspec'

当我使用重定向到文件描述符调用时，

(venv) $ python <(cat tump.py)
lib32
boot
var
app
bin
lost+found
usr
snap
vmlinuz
initrd.img
root
srv
proc
home
lib
lib64
sys
initrd.img.old
mnt
tmp
media
libx32
run
opt
.bash_history
sbin
vmlinuz.old
dev
etc

任何人都可以重现这个吗？我想我正在失去理智。

您的路径上有一个不同的文件inspect.py，这就是正在导入的文件。添加

import inspect
print(inspect.__file__)

到你的程序开始来帮助找到这个。就其本身而言，这是许多问题的重复。您的有趣之处在于重定向正在改变路径。如果我们print(sys.path[:3])在创建 local 后添加到 fs.sshfs 的导入inspect.py，我会得到：

(36) dsm@winter:~/coding$ python <(cat tump.py)
/home/dsm/sys/miniconda3/envs/36/lib/python3.6/inspect.py
['/dev/fd', '/home/dsm/sys/miniconda3/envs/36/lib/python36.zip', '/home/dsm/sys/miniconda3/envs/36/lib/python3.6']
(36) dsm@winter:~/coding$ python tump.py 
/home/dsm/coding/inspect.py
['/home/dsm/coding', '/home/dsm/sys/miniconda3/envs/36/lib/python36.zip', '/home/dsm/sys/miniconda3/envs/36/lib/python3.6']
Traceback (most recent call last):
  File "tump.py", line 6, in <module>
    from fs.sshfs import SSHFS
[...]
AttributeError: module 'inspect' has no attribute 'getmro'

文件描述符版本起作用的原因是因为有效的“本地”路径是 now/dev/fd而不是/home/dsm/coding，并且/dev/fd不包含 inspect.py 冲突。会有细微的差异（我使用的是 3.6 等），但可能是相同的原因。
