I have had the same problem when I used easy-install to install pip for python 2.7.14. For me the solution was (might not be the best, but worked for me, and this is probably the simplest) that the folder that contained the easy-install.py also contained a folder pkg_resources, and i have copy-pasted this folder into the same folder where my pip-script.py script was (python27\Scripts). Since then, I found it in the python27\Lib\site-packages\pip-9.0.1-py2.7.egg\pip\_vendor folder as well, it might be a better solution to modify the pip-script.py file to import this.

如果您使用的是Python 3，则应该使用pip3而不是pip。该命令类似于$ pip3 install requirements.txt

如果你在通过conda安装的应用程序中遇到这个问题，解决方案(如此错误报告中所述)只是简单地安装安装工具:

conda install setuptools

我之前有这个错误，最高评级的答案给了我一个错误，试图下载ez_setup.py文件。我找到了另一个来源，所以你可以运行命令:

curl http://peak.telecommunity.com/dist/ez_setup.py | python

我发现我还必须使用sudo来让它工作，所以你可能需要运行:

sudo curl http://peak.telecommunity.com/dist/ez_setup.py | sudo python

我还创建了另一个可以下载脚本的位置:

https://gist.github.com/ajtrichards/42e73562a89edb1039f3

看起来他们已经离开bitbucket，现在在github (https://github.com/pypa/setuptools)

执行的命令为:

wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
