问题
I am trying to find a temp directory , but when i am trying to get the directory using
tempfile.gettempdir()
it's giving me error of
File "/usr/lib/python2.6/tempfile.py", line 254, in gettempdir
tempdir = _get_default_tempdir()
File "/usr/lib/python2.6/tempfile.py", line 201, in _get_default_tempdir
("No usable temporary directory found in %s" % dirlist))
IOError: [Errno 2] No usable temporary directory found in ['/tmp', '/var/tmp', '/usr/tmp', '/home/openerp/openerp-server']
The permission on the directory is 777 owned by root.
回答1:
This kind of error occured in two case
- permission(should be drwxrwxrwt and owened by root)
- space
To check space(disk usage)just run the command on terminal
df -h
Will list the disk usage on unix and get the output like
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 28G 15G 12G 58% /
If the root(mounted on /) usage is 100%.
You need to clean the tmp directory or restart the machine or make some space on the root.
回答2:
This error can occur when the file system has been switched to read-only mode.

I had the same problem while running a python script in Docker. The following command fixed it for me:
docker rmi $(docker images --quiet --filter "dangling=true")
回答4:
Problem can also occur if inode are full.
You can type df -i
# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
udev 253841 322 253519 1% /dev

I got the same issue when there was no space on /.
Issue:
File "/usr/lib64/python2.6/tempfile.py", line 201, in _get_default_tempdir("No usable temporary directory found in %s" % dirlist))
IOError: [Errno 2] No usable temporary directory found in ['/tmp', '/var/tmp', '/usr/tmp', '/'] [FAILED]
[root@master hue]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_master-lv_root
35G 34G 0 100% /tmpfs
7.8G 72K 7.8G 1% /dev/shm/dev/sda1
477M 34M 418M 8% /boot
When I cleared out some space then it worked fine for me.
[root@master log]# service hue start
Starting hue: [ OK ]
[root@master log]#

definately a disk space issue,
on terminal, type df -h
you should see output like below ( notice the 100% on one of the filesystems)
$ df -h
Filesystem Size Used Avail Use% Mounted on
udev 992M 0 992M 0% /dev
tmpfs 200M 21M 179M 11% /run
/dev/xvda1 7.8G 7.8G 0 100% /
tmpfs 1000M 0 1000M 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 1000M 0 1000M 0% /sys/fs/cgroup
tmpfs 200M 0 200M 0% /run/user/997
tmpfs 200M 0 200M 0% /run/user/1042
in this case, you need to make space by deleting files, artifacts folders e.t.c on path root /

I had the same issue on the Windows 7x64 machine. It was OK with disk space and permissions.
When I excecuted
tempfile.mkdtemp(prefix='MyPrefix_')
manually in python console the directory %TEMP%\MyPrefix_xxxx was successfully created.
But when I did the same from script I received the error IOError: [Errno 2] No usable temporary directory found in [...].
I solved the problem using dir parameter:
# '.' is a default value for example
tempfile.mkdtemp(prefix='MyPrefix_', dir=os.environ.get('TEMP', '.'))
After that from script it worked well.

I ran into this issue earlier today. I started a query embedded in jupyter before going to lunch, and I returned to jupyter throwing some type of error (can't remember what it was exactly). When I tried restarting jupyter in the terminal, I got the error described in OP's question (no usable temporary directory). The answers above didn't work, so I tried restarting my entire VM, at which point I got the error described here. After following the instructions in that thread's top answer, the problem was resolved.
