UnicodeDecodeError：'utf8'編解碼器無法解碼位置661中的字節0x92：無效起始字節

我試圖通過從https://pip.pypa.io下載get-pip.py來安裝python 2.7.2上的最新點子。我從Windows運行命令提示符下的文件，這種說法UnicodeDecodeError：'utf8'編解碼器無法解碼位置661中的字節0x92：無效起始字節

c:\Python27>pip

我也試圖遵循的步驟從http://arunrocks.com/guide-to-install-python-or-pip-on-windows/。但它不起作用。它仍然給出相同的錯誤追溯。

有沒有人有任何提示分享？我使用Windows 7（64位），蟒蛇2.7.2和EPD 7.2-2

錯誤回溯：

您的*系統上安裝了另一個*包，該包已損壞（非UTF8）元數據。這將是一個艱難的定位;在你的'C：\ Python27 \ lib \ site-packages'目錄下尋找'.egg-info'目錄。 –

對不起，這有些不完整。會發生什麼情況是'pkg_resources'正在加載系統中所有已安裝雞蛋的元數據。其中之一包含非UTF-8編碼的元數據。它很可能是'site-packages'目錄中'.egg-info'目錄中的'PKG_INFO'文件。您可以編輯'C：\ Python27 \ lib \ site-packages \ pip-8.0.2-py2.7.egg \ pip \ _vendor \ pkg_resources \ __ init __。py'來打印正在讀取的元數據文件的文件名嘗試找到這個流氓文件。 –

我編輯了這個文件，並且把打印命令放在這一行 > def get_metadata（self，name）： if name =='PKG-INFO'： with io.open（self.path，encoding ='utf -8'）爲f： metadata = f.read（） ** print（f）** 返回元數據 raise KeyError（「沒有元數據，除了PKG-INFO可用」） –

-1

每上述意見，很可能一個雞蛋信息問題與一些已安裝的庫。

快速的方法來找出哪一個是編輯違規初始化的.py每添加一個print語句：

def get_metadata(self, name): 
    with io.open(self.path, encoding='utf-8') as f: 
     if name=='PKG-INFO': 
      print self.path #ADD THIS

在我的例子（EPD蟒蛇），它確定PySide-1.1.0 -3.egg-info作爲問題......誰知道爲什麼。刪除那個蛋信息讓我超過了錯誤。長期解決方案正在尋找獲得正確或更新的軟件包。
