Nock引发'AssertionError [ERR

我正在尝试使用http://102.10.10.337:9391/v2.0/networks和以下代码来模拟URI nock：

const allowUnmocked = { allowUnmocked: true };

const networkScope = nock('http://102.10.10.337:9391/v2.0/', allowUnmocked)
.persist();

console.log(networkScope);

let checknock = networkScope.post('/networks')
    .reply(200, (uri, networkPayload) => {
        console.log('dockedd');
        return {
            network: {
                'provider:physical_network': null,           
                mtu: 1450
            }
        };
    });

try {
    checknock.done();
} catch (e) {
    console.log(`boom! -> ${e}`); // pass exception object to error handler
} 

运行时，出现以下错误：

AssertionError [ERR_ASSERTION]: Mocks not yet satisfied

可能与重复使用/有关。

const networkScope = nock('http://102.10.10.337:9391/v2.0', allowUnmocked)
// ...
const checknock = networkScope.post('/networks')
