[Error] ws_pae_time.c@174,103: expected ')' before 'PRIi64'

I tried to compile the Blinky example by Mbed CLI, while it was prompted:
https://ibb.co/FhtfkFr

I have already used "sudo pip install -r requirements.txt":
https://ibb.co/NnJfF1T
https://ibb.co/1G8LPFW

After I ran "sudo pip install -U -r requirements.txt" in directory "mbed-os", it was prompted a python module "future" was missing, before I ran "sudo pip install -U -r requirements.txt", it was prompted 3 python modules "future, requests, click" were missing. Then I ran "pip install future" under "mbed-os", it was said "future" has been installed, but there was still error:ws_pae_time.c@174,103: expected ')' before 'PRIi64'.

I found the function where "Error" was prompted:

`int8_t ws_pae_current_time_set(uint64_t time)
{
uint64_t new_system_time;
current_time = time;

tr_debug("Current time set: %"PRIi64, time);

if (ns_time_system_time_read(&new_system_time) == 0) {
// System time has gone backwards
if (new_system_time < current_time || new_system_time > current_time + SYSTEM_TIME_MAXIMUM_DIFF) {
tr_error("FATAL: system time less than reference time or more than 12 months in future: %"PRIi64" reference time: %"PRIi64, new_system_time, current_time);
return -1;
}
}

return 0;

}
`

Should "expected ')' before 'PRIi64'" ?

Start by reproducing the Blinky example build with Mbed CLI and inspect ws_pae_time.c at line 174, especially the ws_pae_current_time_set function and its PRIi64 format strings. Check the compiler output and surrounding includes, then confirm the build completes without the reported parse error.
