OS X Mavericks上的pip install失败并出现错误：/ usr / local / bin / pip：没有这样的文件或目录

Question

I am running the Python 2.7.5 version that came standard with OSX.

I have tried to install pip using sudo easy_install pip AND python get-pip.py

When I try to install pip I get the following error with easy_install:

Processing pip
Running setup.py -q bdist_egg --dist-dir /Users/XXXX/pip/egg-dist-tmp-VtRwku
warning: no files found matching 'pip/cacert.pem'
warning: no files found matching '*.html' under directory 'docs'
warning: no previously-included files matching '*.rst' found under directory 'docs/_build'
no previously-included directories found matching 'docs/_build/_sources'
no previously-included directories found matching 'tasks'
pip 1.6.dev1 is already the active version in easy-install.pth
Installing pip script to /usr/local/bin
error: /usr/local/bin/pip: No such file or directory

When I try to install pip with get-pip.py

Requirement already up-to-date: pip in /Library/Python/2.7/site-packages/pip-1.6.dev1-py2.7.egg

• Nothing shows when I type pip help

Answer 1

@ mirra.p the problem is probably you have two versions of python 2 installed on your PC in different locations and pip of one of the copies of python got removed somehow. so when you try to install the pip for a copy, system says that there is a pip already installed in another location and also the /usr/local/bin folde is also missing the pip file used to installed pip.

already installed pip file's location is this:

Library/Python/2.7/site-packages/pip-1.6.dev1-py2.7.egg

i just solved this issue so i will try to explain it in a way so that beginners also understand it properly

copy the already installed pip file to the location where it is missing instead of installing it through commands as command will detect the already installed pip.

the solution is very simple:

run these commands in a terminal (command prompt) in Ubuntu

to get the location of the pip file already installed

which pip

cp <location provided by which pip> <location where to copy pip file>

cp /Library/Python/2.7/site-packages/pip /usr/local/bin

i used the locations for mirra.p problem.

hope it helps.

The error message and especially the additional diagnostics in comments mentioning Cellar indicate that you have installed another Python version using Homebrew.

Probably simply renaming /usr/local/bin/pip to something else will fix the immediate problem. I'll advise against removing it entirely, at least until you understand what precisely is wrong.

In more detail; to use the system Python, you have to undo whatever Homebrew did when it installed a second Python. For a start, you need to unset all the variables which brew installed (or made you install) in your .bashrc and other locations previously.

If you have orphaned symbolic links in /usr/local/bin which point to locations where no command is installed any longer, you'll want to simply remove those (needs root access). This is a sign of a dirty uninstall; next time, follow the Homebrew instructions for how to remove it and the packages you installed with it.

In more detail, Howebrew will have done something like

ln -s /usr/local/Cellar/something/something/python-2.7.3 /usr/local/bin/python

and if /usr/local/Cellar/something/something now no longer exists, attempting to write something there through the symlink will obviously fail. This seems to be exactly what the pip installer is attempting to do at the very end of the installation.

If you have removed Homebrew permanently, you can edit .bashrc and revert whatever changes Homebrew required there. Some settings may remain active in your already-running shell instances until the next reboot; if you want to fix those, read on.

To temporarily override settings, you can unset your PYTHONPATH to get back the system default behavior. If you have commands in /usr/local/bin shadowing the system default ones, you can temporarily set your PATH to prefer /usr/bin by simply prepending it (this is a temporary hack only);

PATH=/usr/bin:$PATH

The shell commands are suitable for Bash; if you use another shell, adapt accordingly.

If you are getting error: /usr/local/bin/pip: No such file or directory and pip already is installed, do following things to solve this problem:

1. Run which pip . It will give answer like : /usr/local/bin
2. just copy pip file in desired location

here,

cp /usr/local/bin /usr/local/bin/pip

This solved my problem.
