试图在Ubuntu 16.04 LTS上安装ncurses 6.0失败,出现编译错误:

In file included from ./curses.priv.h:325:0,
                 from ../ncurses/lib_gen.c:19:

我正在尝试使用pytest为我的Django项目运行selenium并执行fixture fix/teardown.

我试图遵循最佳实践使用,yield但我收到一个错误:

--- ERROR at setup of test_browsing_check --- 
pytest.fixture functions cannot use ``yield``. Instead write and return an inner function/generator and let the consumer call and iterate over it.:

@pytest.fixture(scope="module")
def browser(request):
    selenium = webdriver.Firefox()
    selenium .implicitly_wait(3)
    yield selenium
    selenium.quit()

你知道它为什么不起作用吗？

然后,我使用了另一个运行良好的代码

@pytest.fixture(scope="module")
def browser(request):
    selenium = webdriver.Firefox()
    selenium.implicitly_wait(3)
    def teardown():
        selenium.quit()
    request.addfinalizer(teardown)
    return selenium

但不建议使用此方法:

此方法仍然完全受支持,但建议从2.10开始产量,因为它被认为更简单,更好地描述了自然代码流.

关于版本的说明:

$ python -V
$ Python 3.5.2 :: Anaconda 4.2.0 (64-bit)

$ django-admin version
$ 1.10.3

提取URL的域名

还有一个解析URL的请求,但我发现了许多不完整或理论上的例子.我想肯定有一些在perl中工作的东西.

我有以下网址:

尝试仅提取域名.例如:

linksyssmartwifi.com
amazon.com
github.com

我曾尝试使用Perl和Vim,但无法完成任务.我的最佳近似值如下

 perl -pe 's!(^https?\://.*[\.](.+\..+?)/.*$)!$1 -- [$2] !g' all_urls_sorted.txt

其中一些被正确解析(见[]),其他不是:

https://sourcemaking.com/
https://stackedit.io/editor

正如我的测试显示的那样,直接从//(以https？://开头)的URL被排除在外.

如果你知道如何解决这个问题,我会非常高兴.

谢谢
