解决方法

这个库是不支持Windows，Windows 系统开发的时候，如果使用了这个库，就会产生一些错误，需要新建一个fcntl.py文件，插入代码：

DN_ACCESS = 1
DN_ATTRIB = 32
DN_CREATE = 4
DN_DELETE = 8
DN_MODIFY = 2
DN_MULTISHOT = 2147483648
DN_RENAME = 16FASYNC = 8192FD_CLOEXEC = 1F_ADD_SEALS = 1033F_DUPFD = 0F_DUPFD_CLOEXEC = 1030F_EXLCK = 4
F_GETFD = 1
F_GETFL = 3
F_GETLEASE = 1025
F_GETLK = 5
F_GETLK64 = 5
F_GETOWN = 9
F_GETSIG = 11F_GET_SEALS = 1034F_NOTIFY = 1026
F_RDLCK = 0F_SEAL_GROW = 4
F_SEAL_SEAL = 1
F_SEAL_SHRINK = 2
F_SEAL_WRITE = 8F_SETFD = 2
F_SETFL = 4
F_SETLEASE = 1024
F_SETLK = 6
F_SETLK64 = 6
F_SETLKW = 7

F_SETOWN = 8
F_SETSIG = 10

F_UNLCK = 2
F_WRLCK = 1LOCK_EX = 2
LOCK_MAND = 32
LOCK_NB = 4
LOCK_READ = 64
LOCK_RW = 192
LOCK_SH = 1
LOCK_UN = 8

将脚本到

D:\ProgramData\anaconda3\Lib\

文件夹下面
