OS: Mac OS X 10.7.5 Python Ver: 2.7.5

操作系统：Mac OS X 10.7.5 Python 版本：2.7.5

I have installed setuptools 1.0 with ez_setup.py from https://pypi.python.org/pypi/setuptoolsThen I download pip.1.4.1 pkg from https://pypi.python.org/pypi/pip/1.4.1.

我已经安装了setuptools的1.0 ez_setup.py从https://pypi.python.org/pypi/setuptools然后我下载pip.1.4.1 PKG从https://pypi.python.org/pypi/pip/1.4.1.

Then I inputed pip install, the error message showed like that

然后我输入pip install，错误信息是这样显示的

Anyone who met the same problem before and can give me some tips to solve it?

任何人以前遇到过同样的问题，可以给我一些解决方法的提示吗？

I ran into this same issue when I attempted to install the nova client.

我在尝试安装 nova 客户端时遇到了同样的问题。

spencers-macbook-pro:python-novaclient root# python  setup.py install    
running install
/usr/bin/python: No module named pip
error: /usr/bin/python -m pip.__init__ install   'pbr>=0.5.21,<1.0' 'iso8601>=0.1.4' 'PrettyTable>=0.6,<0.8' 'requests>=1.1' 'simplejson>=2.0.9' 'six' 'Babel>=0.9.6' returned 1

I use homebrew so I worked around the issue with sudo easy_install pip

我使用自制软件，所以我解决了这个问题 sudo easy_install pip

spencers-macbook-pro:python-novaclient root# brew search pip
aespipe     brew-pip    lesspipe    pipebench   pipemeter   spiped  pipeviewer

If you meant "pip" precisely:

Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can:
    sudo easy_install pip
spencers-macbook-pro:python-novaclient root# sudo easy_install pip

The commands should be similar if you use macports.

如果您使用 macports，命令应该类似。

I downloaded pipbinaries from hereand it resolved the issue.

我pip从这里下载了二进制文件，它解决了这个问题。

In terminal try this:

在终端试试这个：

ls -lA /usr/local/bin | grep pip

in my case i get:

就我而言，我得到：

-rwxr-xr-x 1 root  root      284 Сен 13 16:20 pip
-rwxr-xr-x 1 root  root      204 Окт 27 16:37 pip2
-rwxr-xr-x 1 root  root      204 Окт 27 16:37 pip2.7
-rwxr-xr-x 1 root  root      292 Сен 13 16:20 pip-3.4

So pip2 || pip2.7 in my case works, and pip

所以 pip2 || pip2.7 在我的情况下工作，和 pip

After installing ez_setup, you should have easy_installavailable. To install pipjust do:

安装ez_setup 后，您应该可以easy_install使用了。要安装pip只需执行以下操作：

easy_install pip

I think none of these answers above can fix your problem.

我认为以上这些答案都不能解决您的问题。

I was also confused by this problem once. You should manually install pipfollowing the official guide pip installation(which currently involves running a single get-pip.pyPython script)

我也有一次被这个问题搞糊涂了。您应该pip按照官方指南pip 安装手动安装（目前涉及运行单个get-pip.pyPython 脚本）

after that, just sudo pip install Django. The error will be gone.

在那之后，只是sudo pip install Django。错误将消失。

I had the same problem. My solution:

我有同样的问题。我的解决方案：

For Python 3

对于 Python 3

sudo apt-get install python3-pip

For Python 2

对于 Python 2

I know this thread is old, but I just solved the problem for myself on OS X differently than described here.

我知道这个线程很旧，但我只是在 OS X 上为自己解决了与这里描述的不同的问题。

Basically I reinstalled Python 2.7 through brew, and it comes with pip.

基本上我通过 brew 重新安装了 Python 2.7，它带有 pip。

Install Xcode if not already:

如果还没有安装 Xcode：

xcode-select –install

Install Brew as described here:

按照此处所述安装 Brew ：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then install Python through Brew:

然后通过 Brew 安装 Python：

brew install python

And you're done. In my case I just needed to install pyserial.

你已经完成了。就我而言，我只需要安装 pyserial。

pip install pyserial

On Mac using brewis a better option as apt-getis not available. Command:

在 Mac 上使用brew是更好的选择，因为apt-get不可用。命令：

In case you have both python2 & python3 installed on machine

如果您在机器上安装了 python2 和 python3

python2.7 -m ensurepip --default-pip

simply should solve the issue.

应该可以解决问题。

If instead you are missing pip from python 3 then simply change python2.7to python3in the command above.

相反，如果您缺少 python 3 中的 pip，那么只需在上面的命令中更改python2.7为python3。

I solved a similar error on Linux by setting PYTHONPATH to the site-packages location. This was after running python get-pip.py --prefix /home/chet/pip.

我通过将 PYTHONPATH 设置为站点包位置解决了 Linux 上的类似错误。这是运行后python get-pip.py --prefix /home/chet/pip。

[chet@rhel1 ~]$ ~/pip/bin/pip -V
Traceback (most recent call last):
  File "/home/chet/pip/bin/pip", line 7, in <module>
    from pip import main
ImportError: No module named pip

[chet@rhel1 ~]$ export PYTHONPATH=/home/chet/pip/lib/python2.6/site-packages

[chet@rhel1 ~]$ ~/pip/bin/pip -V
pip 9.0.1 from /home/chet/pip/lib/python2.6/site-packages (python 2.6)
