我正在创建一个程序包，首先我在本地安装它，python setup.py develop我在调用程序时遇到问题
>>> import cstm.artefact as art
>>> art.what_is('Objname', 'en')
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/home/guinsly/development/public/project/jeunesse/canadian_science_and_t
echnology_museum_api/cstm/artefact.py", line 56, in what_is
valeur = open_file(keywords, lang)
File "/home/guinsly/development/public/project/jeunesse/canadian_science_and_t
echnology_museum_api/cstm/artefact.py", line 24, in open_file
book = xlrd.open_workbook(path)
File "/usr/lib/python2.7/dist-packages/xlrd/__init__.py", line 394, in open_wo
rkbook
f = open(filename, "rb")
IOError: [Errno 2] No such file or directory: '/home/guinsly/cstm/data/data.xls'
所以我要创建的程序包就在这条路径上 /home/guinsly/development/public/project/jeunesse/canadian_science_and_technology_museum_api/cstm/
但是程序包尝试.xls在运行bpython控制台时打开我所在的文件。
在我的包装上，我的测试还可以
-> % py.test -v

问题：如何在此功能上正确设置路径
def open_file(keywords, lang = 'en'):
"""
Open and read an Excel file
"""
directory = os.getcwd()
path = directory+"/cstm/data/data.xls"
....
您正在使用相对于当前工作目录的路径，而不是相对于您的项目的路径。当前工作目录由用户设置（例如，基于其在终端中的当前位置）。
使用__file__模块的全局变量来确定模块位置：
import os
module_path = os.path.dirname(os.path.abspath(__file__))
并建立相对于该文件的路径：
path = os.path.join(module_path, "cstm/data/data.xls")
