无法运行pip：UnicodeDecodeError [英] Can't run pip: UnicodeDecodeError

问题描述

我有麻烦使用点。例如：

  pip install numpy --upgrade 
  

给我以下错误：

这里有一些线索：

（i）当我尝试运行Spyder时，我有相同的错误。当我尝试安装其他软件包，例如熊猫，熊猫时也会出现。

（ii）我有这种感觉，这与默认编码有关，因为sys.getdefaultencoding给了我'ascii'

注意，如果我在一个virtualenv中这样做，它的效果很好。

我是ubuntu的新手，所以我可能做错了。

设置：python 2.7.6;点7.1.2; ubuntu 14.04.03。

感谢您的帮助。

解决方案

我有同样的问题。在我的情况下，它来自模块描述中的非标准字符。

我添加了一个

print f.path

在脚本中

< blockquote>

/usr/local/lib/python2.7/dist-packages/pkg_resources / __ init __。py

在2025行之前，这使我能够识别正在提出错误的文件。它似乎是文件

/usr/lib/pymodules/python2.7/rpl-1.5.5.egg-info

其作者的名称包含ö字符，无法读取。我只是在这个文件中用Gorran替换了Gorran，并解决了这个问题。

希望这有帮助。

I have trouble using pip. For example:

pip install numpy --upgrade

Gives me the following error:

        (result, consumed) = self._buffer_decode(data, self.errors, final)
    UnicodeDecodeError: 'utf8' codec can't decode byte 0xb6 in position 147: invalid start byte

Here are some clues:

(i) I have the same error when I try to run Spyder. It also appears when I try to to install other packages wtih pip, pandas for example.

(ii) I have the feeling, that this is related to the default encoding since sys.getdefaultencoding gives me 'ascii'

Note that it works well if I do it in a virtualenv.

I'm new to ubuntu so I might have done someting wrong.

Setup: python 2.7.6; pip 7.1.2; ubuntu 14.04.03.

Thank you for your help.

解决方案

I had the same issue. In my case, it comes from a non-standard character in a module description.

I added a

print f.path

in the script

/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py

before line 2025, which allowed me to identify the file which was raising an error. It appeared to be the file

/usr/lib/pymodules/python2.7/rpl-1.5.5.egg-info

whose author has a name containing the ö character, which can not be read. I simply replaced the "Göran" with "Goran" in this file and it fixed the problem.

hope this helps.
