Windows 10和pip升级 - 访问被拒绝

标签: python windows pip

我做了一个全新的Windows 10安装,安装了python,cygwin和一个名为ConEmu的改进控制台。安装python 3.4.3后,执行:

class ByValue implements Comparator<Map.Entry<String, Integer>> 

得到了这个错误。

pip install -U pip

我已使用预定义的管理员帐户登录,并且临时目录以及Python的安装目录(C:\ Anwendungsentwicklung \ Python34)具有完全访问权限。

请通过设置不同的权限测试所有版本,但Windows不允许我这样做。我甚至添加了#34;每个人&#34;安全选项卡,但这并没有帮助,虽然我记得它与Windows 7一起使用这个&#34;技巧&#34;。它一定是Windows 10的问题。有人可以帮忙吗?

这是完全追溯

File "C:\Anwendungsentwicklung\Python34\lib\site-packages\pip\utils\__init__.py", line 70, in rmtree_errorhandler

PermissionError: [WinError 5] Zugriff verweigert:  'C:\\Users\\ADMINI~1\\AppData\\Local\\Temp\\pip-dxm8d3xg-uninstall\\anwendungsentwicklung\\python34\\scripts\\pip.exe'

现在我在&#34; c:\ anwendungsentwicklung \ python34 \ lib \ shutil.py&#34;中添加了一个断点:

  Exception:

PermissionError: [WinError 5] Zugriff verweigert:  'C:\\Users\\ADMINI~1\\AppData\\Local\\Temp\\pip-k7g0hd6t- uninstall\\anwendungsentwicklung\\python34\\scripts\\pip.exe'

During handling of the above exception, another exception occurred:

  try:
PermissionError: [WinError 5] Zugriff verweigert: 'C:\\Users\\ADMINI~1\\AppData\\Local\\Temp\\pip-k7g0hd6t-uninstall\\anwendungsentwicklung\\python34\\scripts\\pip.exe'

当我执行

# 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())

我得到了这个os.unlink(fullname) # 'C:\\Users\\ADMINI~1\\AppData\\Local\\Temp\\pip-k7g0hd6t- uninstall\\anwendungsentwicklung\\python34\\scripts\\pip.exe' ,所以我用

检查了这个.exe文件的权限
PermissionError

然后返回:&#39; 0o100777&#39;

当我说得对,这意味着每个人(所有者,团体和其他人)的完全许可。

我很沮丧:/ 有人有想法吗?

4 个答案:

答案 0 :(得分:7)

正如here所述,这是Windows限制。简而言之,pip.exe文件正在使用中,因此被锁定且无法删除。使用python -m pip install --upgrade pip

答案 1 :(得分:4)

我在相同情况下的首选是使用管理员权限启动控制台。您可以从开始菜单执行此操作,或者如果您使用的是ConEmu / Cmder,只需以管理员身份运行新的实例/选项卡。

答案 2 :(得分:0)

我遇到了同样的问题。如果您通过右键单击“以管理员身份”运行cmd,它会起作用。

答案 3 :(得分:0)

尝试使用此

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