ImportError：尝试通过pip安装时没有名为_markerlib的模块

Question

有人遇到过同样的问题吗？ 我尝试从SO运行解决方案：

pip install --upgrade distribute

和

pip install --upgrade setuptools

每次都得到相同的结果：

Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-build-JC9mq_/distribute/setup.py", line 58, in <module>
        setuptools.setup(**setup_params)
      File "/usr/lib/python2.7/distutils/core.py", line 151, in setup
        dist.run_commands()
      File "/usr/lib/python2.7/distutils/dist.py", line 953, in run_commands
        self.run_command(cmd)
      File "/usr/lib/python2.7/distutils/dist.py", line 972, in run_command
        cmd_obj.run()
      File "setuptools/command/egg_info.py", line 177, in run
        writer = ep.load(installer=installer)
      File "pkg_resources.py", line 2241, in load
        if require: self.require(env, installer)
      File "pkg_resources.py", line 2254, in require
        working_set.resolve(self.dist.requires(self.extras),env,installer)))
      File "pkg_resources.py", line 2471, in requires
        dm = self._dep_map
      File "pkg_resources.py", line 2682, in _dep_map
        self.__dep_map = self._compute_dependencies()
      File "pkg_resources.py", line 2699, in _compute_dependencies
        from _markerlib import compile as compile_marker
    ImportError: No module named _markerlib

python 2.7，pip 8.1.2

[编辑]创建新环境的解决方案。 使用virtualenv myenv --distribute适用于本地环境，但是当我尝试推送到heroku时，它给出了完全相同的错误：没有名为_markerlib的模块。 所以，问题不仅仅在于本地环境。

我想，我这样修好了。

pip uninstall setuptools
download  https://bitbucket.org/pypa/setuptools/raw/0.7.3/ez_setup.py

然后运行它

pip install %HOME%\Downloads\wheel-0.25.0.tar.gz
pip install  Distribute

我做了这个，所以这会工作

pip install django-validated-file
