pytest pluggy.manager.PluginValidationError: unknown hook 'pytest_namespace'報錯處理辦法

1、背景說明

上週測試的同事說pytest+allure環境在別人電腦上跑沒問題，在她的環境跑卻報錯讓幫看一下。其實pytest只是據說過allure直接沒聽過，但不能直接表示不會，祭出百度大法。

看環境pytest直接以python庫的形式安裝就能夠了：pip install pytest pytest-allure-adaptor pytest-rerunfailures pytest-html

allure安裝也簡單下載解壓而後將bin目錄添加到環境變量便可。下載地址：https://github.com/allure-framework/allure2/releases/tag/2.10.0

 

2、問題處理

2.1 報錯描述

主要運行報錯以下：

pluggy.manager.PluginValidationError: unknown hook 'pytest_namespace' in plugin <module 'allure.pytest_plugin' from 'd:\\language\\miniconda3\\e
nvs\\pytest\\lib\\site-packages\\allure\\pytest_plugin.py'>

完整報錯以下：

2.2 報錯處理

反覆從新建立配置了環境忽然某次成功運行了，回頭排除項目使用中文路徑、python環境使用中文路徑、使用conda發行版後，想起google到的某個頁面說過是版本問題並且本身也按其建議裝了舊版本：

最後肯定確實如其所說，pytest新版本（我當前是4.3.0）運行報錯，換成4.0.2版本就不會報錯：

# 卸載已安裝的pytest
pip uninstall pytest
# 安裝4.0.2版本pytest pip install pytest==4.0.2

成功運行以下圖：
