--------------------

# 一、问题描述 #

通过pip下载Pycharm时报错：

ERROR: Could not find a version that satisfies the requirement HTMLTestRunner
    ERROR: No matching distribution found for HTMLTestRunner

# 二、解决方案 #

只需要在Python安装目录下的Lib文件夹中新建一个名为HTMLTestRunner.py的文件，并在其中写入如下内容（分为Python2和Python3两版）：

## ① Python2 ##

"""
    A TestRunner for use with the Python unit testing framework. It
    generates a HTML report to show the result at a glance.
    
    The simplest way to use this is to invoke its main method. E.g.
    
        import unittest
        import HTMLTestRunner
    
        ... define your tests ...
    
        if __name__ == '__main__':
            HTMLTestRunner.main()
    
    
    For more customization options, instantiates a HTMLTestRunner object.
    HTMLTestRunner is a counterpart to unittest's TextTestRunner. E.g.
    
        # output to a file
        fp = file('my_report.html', 'wb')
        runner = HTMLTestRunner.HTMLTestRunner(
                    stream=fp,
                    title='My unit test',
                    description='This demonstrates the report output by HTMLTestRunner.'
                    )
    
        # Use an external stylesheet.
        # See the Template_mixin class for more customizable options
        runner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'
    
        # run the test
        runner.run(my_test_suite)

"""
    A TestRunner for use with the Python unit testing framework. It
    generates a HTML report to show the result at a glance.
    
    The simplest way to use this is to invoke its main method. E.g.
    
        import unittest
        import HTMLTestRunner
    
        ... define your tests ...
    
        if __name__ == '__main__':
            HTMLTestRunner.main()
    
    
    For more customization options, instantiates a HTMLTestRunner object.
    HTMLTestRunner is a counterpart to unittest's TextTestRunner. E.g.
    
        # output to a file
        fp = file('my_report.html', 'wb')
        runner = HTMLTestRunner.HTMLTestRunner(
                    stream=fp,
                    title='My unit test',
                    description='This demonstrates the report output by HTMLTestRunner.'
                    )
    
        # Use an external stylesheet.
        # See the Template_mixin class for more customizable options
        runner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'
    
        # run the test
        runner.run(my_test_suite)
