我在我的Centos机器上使用Python,当我尝试运行我的程序时,我显示了以下错误:
Running setup.py egg_info for package pyepr
Traceback (most recent call last):
File "<string>", line 16, in <module>
File "/tmp/pip-build-root/pyepr/setup.py", line 68, in <module>
print('using EPR C API sources at "{}"'.format(eprsrcdir))
ValueError: zero length field name in format
Complete output from command python setup.py egg_info:
Traceback (most recent call last):
File "<string>", line 16, in <module>
File "/tmp/pip-build-root/pyepr/setup.py", line 68, in <module>
print('using EPR C API sources at "{}"'.format(eprsrcdir))
ValueError: zero length field name in format
我已经检查了关于这个主题的其他问题,我已经安装了Python 2.7.6并将其设置为我的默认配置,如下所示....
$ python …我是RxJava的新手,我需要以异步方式使用Observable功能.
我还需要使用超时:在我的例子中,我希望每个进程在1秒或更短的时间内结束.
这就是我现在所做的:
public static void hello(String name) throws IOException {
Observable<String> obs2 = Observable.just(name).timeout(1000, TimeUnit.MILLISECONDS).subscribeOn(Schedulers.io());
obs2.subscribe(new Action1<String>() {
@Override
public void call(String s) {
if("CCCCC".equals(s)){
try {
Thread.sleep(3200);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
System.out.println(s + " " + new Date() +" "+Thread.currentThread().getName());
}
});
}
public static void main(final String[] args) throws InterruptedException, IOException {
hello("AAAAA");
hello("CCCCC");
hello("BBBBBB");
System.in.read();
}
结果:
