importorror:没有名为pip的模块

Question

操作系统：Mac OS X 10.7.5 Python版本：2.7.5

我已经从https://pypi.python.org/pypi/setuptools安装了setuptools 1.0和ez_setup.py 然后我从https://pypi.python.org/pypi/pip/1.4.1下载pip.1.4.1pkg。

iTerm中的Run（sudo）python setup.py install显示

然后我输入pip install，错误消息显示如下

Traceback (most recent call last):   File
"/Library/Frameworks/Python.framework/Versions/2.7/bin/pip", line 9,
in <module>
load_entry_point('pip==1.4.1', 'console_scripts', 'pip')()   File "build/bdist.macosx-10.6-intel/egg/pkg_resources.py", line 357, in

以前遇到过同样问题的人能给我一些解决方法吗？

Answer 1

安装ez_setup后，应该有easy_install可用。要安装pip，请执行以下操作：

easy_install pip

Answer 2

在Mac上，使用brew是一个更好的选择，因为apt get不可用。 命令：

如果机器上同时安装了python2和python3

python2.7 -m ensurepip --default-pip

只是应该解决这个问题。

如果python 3缺少pip，那么只需在上面的命令中将python2.7更改为python3。

Answer 3

我也有同样的问题。 我的解决方案：

对于Python 3

sudo apt-get install python3-pip

对于Python 2

sudo apt-get install python-pip
