Python 使用PIP安装程序包时出现Mimetypes.init（）错误

编辑：通过打开C:\Python27\Lib\mimetypes.py并将代码下方添加到try块来解决问题：

我从3天前开始搜索，但解决这个问题对我来说太难了。我不明白问题出在哪里

我尝试使用GitHub、PowerShell 3等安装我的软件包。所有这些都不起作用。除了皮普·威奇似乎有点小毛病

当我尝试使用PIP安装tweepy时，此错误会附加：

你能给我解释一下，怎么做吗

看起来您的windows注册表中有一个mimetype导致了问题。您可以运行以下脚本以确定它是哪一个脚本：

import _winreg


def find_funky_mimetype():
    default_encoding = sys.getdefaultencoding()
    with _winreg.OpenKey(_winreg.HKEY_CLASSES_ROOT,
                         r'MIME\Database\Content Type') as mimedb:
        i = 0
        while 1:
            try:
                ctype = _winreg.EnumKey(mimedb, i)
            except EnvironmentError:
                break
            print 'testing:', `ctype`,
            try:
                ctype = ctype.encode(default_encoding) # omit in 3.x!
            except UnicodeEncodeError:
                print 'expected failure'
            except Exception as e:
                print 'unexpected failure:', e
            else:
                print 'ok.'
            i += 1


if __name__ == "__main__":
    find_funky_mimetype()

对此，您应该怎么做完全取决于您自己，以及您对什么感到满意，例如，从注册表中删除有问题的mimetype，或者在'c:\Python27\lib\mimetypes.py'的第252行中添加一个通用类型，与我上面所做的类似。

更改第250行

except (UnicodeEncodeError, UnicodeDecodeError):
    pass

pip-version打印出什么，C:\Users\user\pip\pip.log说什么？pip-version什么都不做，它说找不到程序。日志文件在这里：当您调用它来安装C:\Users\user>pip install tweepy时，pip-version怎么能什么都不做呢..因为由于错误，pip没有安装你很困惑。pip是用来安装tweepy的。我可以看到pip正在运行，因为当您运行pip install tweepy时，您会得到输出。这运行pip告诉它安装tweepy包。运行pip install tweepy的方式与运行pip-version的方式有什么区别？我在运行脚本时没有任何错误，所有的模拟类型都正常。ps：您忘了导入系统^^

except (UnicodeEncodeError, UnicodeDecodeError):
    pass
