Windows 10 and pip upgrading - Access denied

Question

I have done a fresh Windows 10 install, installed python, cygwin and a improved console called ConEmu. After installing python 3.4.3 I execute:

pip install -U pip

And got this error.

File "C:\Anwendungsentwicklung\Python34\lib\site-packages\pip\utils\__init__.py", line 70, in rmtree_errorhandler
  os.makedirs(path)
PermissionError: [WinError 5] Zugriff verweigert:  'C:\\Users\\ADMINI~1\\AppData\\Local\\Temp\\pip-dxm8d3xg-uninstall\\anwendungsentwicklung\\python34\\scripts\\pip.exe'

I'm logged in with pre-defined Administrator account and the temp dir as well as the installation dir of Python (C:\Anwendungsentwicklung\Python34) has full access.

Please I have tested all variations by setting different rights but Windows won't let me. I even added "Everyone" to security tab but this didn't help although I remember it was working with Windows 7 with this "trick". It must be a problem with Windows 10. Can someone help??

This is full traceback

  Exception:

During handling of the above exception, another exception occurred:

Now I added a breakpoint in "c:\anwendungsentwicklung\python34\lib\shutil.py":

# version vulnerable to race conditions
def _rmtree_unsafe(path, onerror):
try:
    if os.path.islink(path):
        # symlinks to directories are forbidden, see bug #1669
        raise OSError("Cannot call rmtree on a symbolic link")
except OSError:
    onerror(os.path.islink, path, sys.exc_info())
    # can't continue even if onerror hook returns
    return
names = []
try:
    names = os.listdir(path)
except OSError:
    onerror(os.listdir, path, sys.exc_info())
for name in names:
    fullname = os.path.join(path, name)
    try:
        mode = os.lstat(fullname).st_mode
    except OSError:
        mode = 0
    if stat.S_ISDIR(mode):
        _rmtree_unsafe(fullname, onerror)
    else:
        try:
            #import pdb
            os.unlink(fullname)
            #pdb.set_trace()
        except OSError:
            import pdb; pdb.set_trace()
            print(fullname)
            import getpass
            print(getpass.getuser())
            onerror(os.unlink, fullname, sys.exc_info())
try:
    os.rmdir(path)
except OSError:
    onerror(os.rmdir, path, sys.exc_info())

When i execute

os.unlink(fullname) # 'C:\\Users\\ADMINI~1\\AppData\\Local\\Temp\\pip-k7g0hd6t- uninstall\\anwendungsentwicklung\\python34\\scripts\\pip.exe'

I get this PermissionError, so i checked the rights of this .exe file with

oct(os.stat(fullname)[ST_MODE])

and it returns: '0o100777'

And when i'm right, this means full permission for everyone (owner, group and others).

I'm frustrated :/ Someone an idea?

Solution 1

As discussed here, it's a Windows limitation. In brief, the pip.exe file is in use and thus locked and can't be deleted. Use python -m pip install --upgrade pip.

Solution 2

My first choice in the same situation is to start console with administrator rights. You can do that from start menu or if you are using ConEmu / Cmder, just run new instance / tab as administrator.

Solution 3

Try using this

python -m pip install --user --upgrade pip

Solution 4

I had the same problem. It worked if you run cmd "as administrator" by right-clicking.

Did you try running the command while being elevated?

[Thane Plummer]

It's not your ConEmu console -- I just upgraded and got the same error using the standard Cygwin console.

[FalloutBoy]

@poke sure. But like Thane Plummer says, it doesn't matter which console. Windows 10 has something generally crapped -.-

[poke]

I meant running e.g. cmd.exe as administrator (via right-click).

[FalloutBoy]

yes tried it, but same problem

[Eryk Sun]

@poke, the "Administrator" account (SID S-1-5-21-...-500) is disabled by default because it's not subject to UAC. It gets logged on with an unrestricted token that has the BUILTIN\Administrators (S-1-5-32-544) group enabled, an elevated (High) integrity label (S-1-16-12288), and the full set of administrator privileges such as SeTakeOwnershipPrivilege.

[Eryk Sun]

If pip.exe is currently running, then the file is memory-mapped by the memory manager and can't be deleted until the process exits or is forcibly terminated.

Please give extra information by editing your question rather than adding it as an answer (which it isn't).

[FalloutBoy]

@Roland Smith seen that in other threads, sorry. Solved the problem for me. It's a windows limitation and wasn't fixed since yet. Use python -m pip install --upgrade pip. Discussed here: github.com/pypa/pip/issues/1299 Summary: The file is locked/ in use and those files can't be deleted. Thanks all!

[Don O'Donnell]

Just to clarify: open start menu, right click 'command prompt', select 'more', click 'Run as administrator'.

[Pirate X]

Thanks. This helped !

[Heewoon]

To summarize, pip is actually upgraded but that fact is not known by python or pip itself. And the error is just fake, or there was an error in the code, that tried to access another directory without elevation.

@RolandSmith The question was "Can someone help?" and this post is an answer to that question.
