linux服务器怎么安装pip

1、先说一下什么是pip

pip 是“A tool for installing and managing Python packages.”，也就是说pip是python的软件安装工具

2、下面介绍怎么在linux下安装pip

下载pip到/usr/local/src

# cd /usr/local/src

# wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate

如果提示：-bash: wget: command not found

那么安装wget，执行如下：

# yum -y install wget

解夺安装pip

# tar -xzvf pip-1.5.4.tar.gz

# cd pip-1.5.4

# python setup.py install

如果安装报下面的错：

Traceback (most recent call last):

File "setup.py", line 6, in <module>

from setuptools import setup, find_packages

ImportError: No module named setuptools

那么就要先安装setuptools包

(1)下载setuptools包

# wget http://pypi.python.org/packages/source/s/setuptools/setuptools-2.0.tar.gz

(2)解压setuptools包

# tar zxvf setuptools-2.0.tar.gz

# cd setuptools-2.0

(3)编译setuptools

# python setup.py build

(4)开始执行setuptools安装

# python setup.py install

安装完成setuptools包后，在重新执行：

# cd /usr/local/src/pip-1.5.4

# python setup.py install

至此pip安装完成

3、linux下pip使用参数

# pip --help

Usage:

pip <command>[options]

Commands:

install Install packages.

uninstall Uninstall packages.

freeze Output installed packages in requirements format.

listList installed packages.

showShow information about installed packages.

search Search PyPI for packages.

wheel Build wheels from your requirements.

zip DEPRECATED. Zip individual packages.

unzip DEPRECATED. Unzip individual packages.

bundle DEPRECATED. Create pybundles.

helpShow help for commands.

General Options:

-h, --help Show help.

-v, --verbose Give more output. Option is additive, and can be used up to 3 times.

-V, --version Show version and exit.

-q, --quiet Give less output.

--log-file <path> Path to a verbose non-appending log, that only logs failures. This log is active by default at /root/.pip/pip.log.

--log <path> Path to a verbose appending log. This log is inactive by default.

--proxy <proxy>Specify a proxy in the form [user:passwd@]proxy.server:port.

--timeout <sec>Set the socket timeout (default 15 seconds).

--exists-action <action> Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup.

--cert <path> Path to alternate CA bundle.

咳咳，实际上pip默认路径是/usr/local/lib/python2.7/dist-packages

但是注意，

root用户用pip的时候一定要是

这个时候才装到/usr/local/lib/python2.7/dist-packages 下

如果root用户的命令是

此时装到了/home/那个root用户/.local/lib/python2.7/site-packages 下

只要保证非root用户的环境变量PATH里有/usr/local/bin 就没问题啦！
