ModuleNotFoundError: No module named 'fcntl'

python 3.6 使用
import acm

ENDPOINT = "acm.aliyun.com:8080"
NAMESPACE = "base-dev"
AK = "××××××××××"
SK = "×××××××××××××××××"

# get config
client = acm.ACMClient(ENDPOINT, NAMESPACE, AK, SK)
data_id = "cn.jfhealthcare.devops:opssampler.ini"
group = "DEFAULT_GROUP"

# add watch
#import time
#client.add_watcher(data_id, group, lambda x:print("config change detected: " + x))
#time.sleep(5) # wait for config changes

if(__name__=='__main__'):
print(client.get(data_id, group))
#client.list_all()

Start by running the reported Python 3.6 example with `import acm` and `ACMClient`, then inspect the package entry point and the dependency that imports `fcntl`. Confirm the supported environment and define done as importing the SDK and reaching the configuration lookup without this error.
