看到一个人example，其中一些人已经开始工作但是我不清楚他们是否使用了python2或3 venv？有人可以帮忙吗？

看起来您在同一目录中有一个名为@Test
public void testRetry() throws IOException {
server.stubFor(get(urlPathEqualTo(RANDOM_JOKE_URI))
.inScenario("Feign retry")
.whenScenarioStateIs(STARTED)
.willReturn(badRequest())
.willSetStateTo("1"));
server.stubFor(get(urlPathEqualTo(RANDOM_JOKE_URI))
.inScenario("Feign retry")
.whenScenarioStateIs("1")
.willReturn(badRequest())
.willSetStateTo("2"));
server.stubFor(get(urlPathEqualTo(RANDOM_JOKE_URI))
.inScenario("Feign retry")
.whenScenarioStateIs("2")
.willReturn(ok()
.withHeader("Content-Type", "application/json")
.withBody(copyToByteArray(getClass().getResourceAsStream("/joke.json")))));
TestSubscriber<JokeServiceResponse> subscriber = new TestSubscriber<>();
TestScheduler scheduler = new TestScheduler();
// GOTCHA ALERT: must use defer for the Observable to be reevaluated
Observable.defer(() -> client.tellAJoke()
.toObservable())
.retryWhen(errors -> onErrorTryAgain(errors, scheduler))
.subscribe(subscriber);
scheduler.advanceTimeBy(2, TimeUnit.SECONDS);
subscriber.assertNoValues();
scheduler.advanceTimeBy(4, TimeUnit.SECONDS);
subscriber.assertNoValues();
subscriber.awaitTerminalEvent(10, TimeUnit.SECONDS);
subscriber.assertNoErrors();
assertThat(subscriber.getOnNextEvents())
.hasSize(1)
.is(new Condition<JokeServiceResponse>() {
@Override
public boolean matches(JokeServiceResponse response) {
assertResponse(response);
return true;
}
}, atIndex(0));
}
private Observable<?> onErrorTryAgain(Observable<? extends Throwable> errors, Scheduler scheduler) {
return errors
.zipWith(Observable.range(1, 5), (t, i) -> new SimpleImmutableEntry<Integer, Throwable>(i, t))
.flatMap(e -> {
// Can inspect Throwable here and decide whether to retry or return Observable.error
return Observable.timer((long) Math.pow(2, e.getKey()),
TimeUnit.SECONDS, scheduler);
});
}
的文件与google.py python namespace packages冲突。

请参阅评论中的@proppy回复。会早点关闭，但我只收到答案的通知，但没有收到评论???
