在PyDev中配置py.test（Python 3，Mac）

Question

我有一台Mac，並且已將py.test安裝到Python 3庫（而不是Apple的標准Python 2.7庫）。 這是因為我正在使用Python 3。

但是，當我在PyDev中運行py.test時，會發生以下錯誤。 關於如何解決這個問題的任何解釋？ 我已經思考了很長時間了。

注意：我已經安裝了LiClipse中捆綁的PyDev。 我已經根據文檔配置了py.test測試運行程序：

--maxfail=2 --tb=native

然后，我根據py.test的文檔運行了一個簡單的py.test測試文件：

def func(x):
    return x + 1

def test_answer():
    assert func(3) == 5

Answer 1

pytest配置似乎正確。

因此，要檢查一些事情：

1. 您可以使用py.test filename在命令行中（不在LiClipse中）運行它嗎？

2. 您如何精確地運行測試？ （該文件或運行文件夾是Ctrl + F9還是？）

錯誤似乎是在評估pytest中的標記（即pytest.mark.xxx）時出現的，您的項目其他部分是否可能存在無效標記？
