MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker") TypeError解决方法

问题描述

安装qira的时候出现了这个错误，大概如下

Processing ./qiradbCollecting https://pypi.python.org/packages/source/p/pyparsing/pyparsing-1.5.7.tar.gz#md5=9be0fcdcc595199c646ab317c1d9a709 (from -r requirements.txt (line 15))  Using cached pyparsing-1.5.7.tar.gz    Complete output from command python setup.py egg_info:    Traceback (most recent call last):      File "<string>", line 1, in <module>      File "/home/anciety/qira/venv/lib/python2.7/site-packages/setuptools/__init__.py", line 12, in <module>        import setuptools.version      File "/home/anciety/qira/venv/lib/python2.7/site-packages/setuptools/version.py", line 1, in <module>        import pkg_resources      File "/home/anciety/qira/venv/lib/python2.7/site-packages/pkg_resources/__init__.py", line 72, in <module>        import packaging.requirements      File "/home/anciety/qira/venv/lib/python2.7/site-packages/packaging/requirements.py", line 59, in <module>        MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")    TypeError: __call__() takes exactly 2 arguments (1 given)    ----------------------------------------Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-AEFGO0-build/

大概意思应该就是pip安装pyparsing的时候出错了

问题解决

sudo pip install --upgrade --force pipsudo pip install setuptools==33.1.1

不过这应该是个临时解决方法，情况应该是setuptools或者pip中有bug，只能先这样临时解决。
