我正在尝试在python上安装SSL的安全修复程序：

有什么建议吗？我在一些搜索后尝试了超时和默认超时，但我认为它们完全被忽略了。
代码上的我看到了：
def acquire(self, timeout=None):
timeout = timeout is not None and timeout or self.timeout
end_time = time.time()
if timeout is not None and timeout > 0:
end_time += timeout
if timeout is None:
wait = 0.1
else:
wait = max(0, timeout / 10)
while True:
try:
os.mkdir(self.lock_file)
except OSError:
err = sys.exc_info()[1]
if err.errno == errno.EEXIST:
# Already locked.
if os.path.exists(self.unique_name):
# Already locked by me.
return
if timeout is not None and time.time() > end_time:
if timeout > 0:
raise LockTimeout("Timeout waiting to acquire"
" lock for %s" %
self.path)
else:
# Someone else has the lock.
raise AlreadyLocked("%s is already locked" %
self.path)
**time.sleep(wait)**
else:
# Couldn't create the lock for some other reason
raise LockFailed("failed to create %s" % self.lock_file)
else:
open(self.unique_name, "wb").close()
return
如何解决此问题？有人有想法吗？
答案 0 :(得分：0)
您可以检查显示的日志中是否存在以下异常： 回溯（最近一次调用最后一次）：
文件 “C：\ python34 \ LIB \站点包\ pip_vendor \锁文件\ mkdirlockfile.py” 第40行，收购 os.mkdir（self.lock_file）FileExistsError：[WinError 183]当该文件已存在时无法创建文件： “C：\用户\\应用程序数据\本地\ PIP \缓存\ HTTP \˚F。\ E \ d \ 0 。\ E \ fed0ed508030b766d5b0c2792132c8bf197804464765b46b361f93a4.lock'
如果您可以尝试删除pip目录并再试一次
