Question

我在Windows 8.1 64位操作系统上运行Python（x，y）2.7.10.0。我之前使用过pip来安装一些软件包，但现在我尝试了

pip install nltk
pip install pycallgraph
pip search nltk
pip install selenium

我收到以下错误

    C:\Python27\lib\site-packages\xy>pip search nltk
    Traceback (most recent call last):
      File "C:\Python27\Scripts\pip-script.py", line 5, in <module>

Answer 1

我在Windows上也有这个问题。无论我尝试用pip做什么，我都会收到这个错误。解决方案是：

python -m pip install -U pip setuptools

我在install-pip说明页面找到了它：https://packaging.python.org/installing/#install-pip-setuptools-and-wheel
