#1.报错信息：
install失败报install pbr failed

报错信息如下：

#2.定位原因
由于系统编码导致，
默认的是

[root@hd103 pip]# cat /etc/locale.conf
LANG="zh_CN.UTF-8"
[root@hd103 pip]#

#3.解决方案：
##3.1.解决办法
###3.1.1.第一种：这里我们将Python的默认编码方式修改为utf-8，就可以规避上述问题的发生，具体方式，我们在Python文件的前面加上如下代码：

import sys
defaultencoding = 'utf-8'
if sys.getdefaultencoding() != defaultencoding:
    reload(sys)
    sys.setdefaultencoding(defaultencoding)

###3.1.2第二种：我们在/usr/lib/python2.7/site-packages/目录下添加一个sitecustomize.py文件，内容如下：

import sys
sys.setdefaultencoding('utf-8')
这种方式可以解决所有项目的encoding问题，具体说明可参考/usr/lib/python2.7/site.py文件：


/data/install/pip/pip-9.0.0/build/lib/pip/_vendor/html5lib/treewalkers/etree.py
在首行加上：
import sys
sys.setdefaultencoding('utf-8')

/data/install/pip/pip-9.0.0/build/lib/pip/_vendor/html5lib/treewalkers/etree.py
byte-compiling build/bdist.linux-x86_64/egg/pip/_vendor/html5lib/treewalkers/etree.py to etree.pyc
  File "build/bdist.linux-x86_64/egg/pip/_vendor/html5lib/treewalkers/etree.py", line 13
   修改前： from pip._vendor. import string_types         --->         修改后：   from pip._vendor.six  import string_types

vim /data/install/pip/pip-9.0.0/build/lib/pip/_vendor/html5lib/treewalkers/etree.py

###3.1.3.第三种修改方法（改系统语言）

vi  /etc/locale.conf
      LANG="en_US.UTF-8"
export LANG=en_US.UTF-8

好了，聪明如你，知道了bkcec install paas报错时的解决方案，是不是很欢喜 ^_
