Question

更新Debian（Jessie）后，pytest不起作用：

#py.test

Traceback (most recent call last):
  File "/usr/bin/py.test", line 5, in <module>
    sys.exit(load_entry_point('pytest==2.4.2', 'console_scripts', 'py.test')())
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 348, in      load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 2311, in     load_entry_point
    return ep.load()
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 2024, in load
    if require: self.require(env, installer)
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 2037, in require
    working_set.resolve(self.dist.requires(self.extras),env,installer)))
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 571, in resolve
    raise VersionConflict(dist,req) # XXX put more info here
pkg_resources.VersionConflict: (py 1.4.15 (/usr/lib/python2.7/dist-packages), Requirement.parse('py>=1.4.17'))

如何修复此错误？ Thanx提前！

Answer 1

/usr/local/lib/python2.7/dist-packages中的文件属于使用pip，easy_install或python setup.py安装的python包。系统更新可能搞砸了一些依赖项。这有用吗？

sudo apt-get install python-pip
sudo /usr/bin/pip install -U pytest

Answer 2

某些实例可能有多个pytest在运行。尝试：

sudo apt-get remove pytest

然后再次进行测试。

Pytest版本冲突错误
