Question

我正在尝试为Python 3.5安装一些软件包（pyodbc，pandas），但这个过程正在陷入困境。我尝试的第一件事是：

C:\Program Files (x86)\Python 3.5\Scripts> pip install pyodbc

这给了我以下

Traceback (most recent call last):
  File "C:\Program Files (x86)\Python 3.5\Scripts\pip-script.py", line 9, in <module> load_entry_point('pip==8.1.2', 'console_scripts', 'pip')()
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\pkg_resources\__init__.py", line 552, in load_entry_point return get_distribution(dist).load_entry_point(group, name)
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\pkg_resources\__init__.py", line 2672, in load_entry_point
return ep.load()
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\pkg_resources\__init__.py", line 2345, in load     return self.resolve()
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\pkg_resources\__init__.py", line 2351, in resolve
module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\pip-8.1.2-py3.5.egg\pip\__init__.py", line 14, in <module>
from pip.utils import get_installed_distributions, get_prog
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\pip-8.1.2-py3.5.egg\pip\utils\__init__.py", line 27, in <module>
from pip._vendor import pkg_resources
ImportError: cannot import name 'pkg_resources'

然后我尝试

C:\Program Files (x86)\Python 3.5\Scripts> pip install pkg_resources

产生相同的pkg_resources错误。

接下来我尝试

C:\Program Files (x86)\Python 3.5\Scripts> easy_install-3.5 install pkg_resources

和

C:\Program Files (x86)\Python 3.5\Scripts> easy_install-3.5 pkg_resources

两者都产生

Searching for pkg-resources
Reading https://pypi.python.org/simple/pkg_resources/
No local packages or download links found for pkg-resources error: Could not find suitable distribution for Requirement.parse('pkg-resources')

进一步搜索后，有人建议setuptools可能已过期。目前我有16.0的setuptools，而我看到的最新版本是25.1.6。当我尝试使用pip更新setuptools时，

C:\Program Files (x86)\Python 3.5\Scripts> pip install -U setuptools

我再次收到pkg_resources错误。如果我使用easy_install-3.5进行更新，它会再次安装16.0版本。

接下来，我尝试通过下载.whl文件手动安装setuptools。

C:\Program Files (x86)\Python 3.5\Scripts>pip install "C:\Users\xxxx\Downloads\setuptools-25.1.6-py2.py3-none-any.whl"

但是再次出现了pkg_resources错误。

由于我的目标是简单地安装软件包，我还尝试了

C:\Program Files (x86)\Python 3.5\Scripts> easy_install-3.5 install pyodbc

如上所述，它提供相同的No Local包或下载链接错误。相反，如果我运行

C:\Program Files (x86)\Python 3.5\Scripts> easy_install-3.5 pyodbc

我得到了

C:\Program Files (x86)\Python 3.5\Scripts>easy_install-3.5 pyodbc

有什么想法吗？

Python安装包错误（无法导入名称'pkg_resources'）
