Question

这是我尝试安装sqalchemy时获得的内容

Traceback (most recent call last):
  File "/usr/bin/easy_install", line 11, in <module>
    load_entry_point('setuptools==33.1.1', 'console_scripts', 'easy_install')()
  File "/home/j/.local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 572, in load_entry_point

    return ep.load()
  File "/home/j/.local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2408, in load
    return self.resolve()
  File "/home/j/.local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2414, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "/usr/lib/python2.7/dist-packages/setuptools/command/easy_install.py", line 51, in <module>
    from setuptools.archive_util import unpack_archive
  File "/usr/lib/python2.7/dist-packages/setuptools/archive_util.py", line 12, in <module>
    from pkg_resources import ContextualZipFile
ImportError: cannot import name ContextualZipFile

我尝试过安装和卸载setuptools。

我还尝试从pkg_resources import ensure_directory，ContextualZipFile＆＃34;更改＆＃34;来自pkg_resources的导入ensure_directory＆＃34;在我的usr / local / lib / python2.7 / dist-packages / setuptools / archive_util.py中。但是我收到了错误

    with ContextualZipFile(filename) as z:

我也试过直接导入pkg_resources，但它仍然无法找到ContextualZipFile。我收到错误：

NameError: global name 'ContextualZipFile' is not defined

我用 python版本= 2.7.13和点数版本= 9.0.1

我也是在虚拟环境中做到这一点

Answer 1

这似乎是一个常见的错误 https://github.com/pypa/setuptools/issues/252

最简单的方法是使用替代方案，例如： yum -y install python-pip

无法导入名称ContextualZipFile
