我做到了export PYTHONPATH=$PYTHONPATH:/home/User/folder/test.然后我在进入/home/User/并检查时运行python sys.path- 这是正确的.
>>> import sys
>>> sys.path
['', '/usr/local/lib/python2.7/dist-packages/gitosis-0.2-py2.7.egg',
'/home/User', '/home/User/folder/test','/usr/lib/python2.7',
'/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk',
'/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload',
'/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']
然后我尝试打开这样的文件/home/User/folder/test/pics/text/text.txt:
>>>file = open('pics/text/text.txt','r')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IOError: [Errno 2] No such file or directory:
正如您所看到的,文件路径的前半部分是在$PYTHONPATH,而后半部分是作为open()函数的参数给出的.为什么不起作用？我应该改变什么？
当我从/home/User/folder/test(导出的路径)运行python 并尝试打开文件时 - 它工作.
