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.

pip是python的一个工具，用来安装python包特别方便。

Linux系统是是内置python程序，因为许多Linux内置文件都是使用python来编写的，比如说yum。

1.脚本安装

通过脚本的方式可以保证都能够安装到最新版本的pip，同时 *** 作简单。

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

python get-pip.py

2.源码包安装

下载地址：https://pypi.org/search/?q=pip

wget --no-check-certific ate https://pypi.python.org/packages/source/p/pip/pip-10.0.1.tar.gz >>/dev/null

tar -zvxf pip-10.0.1.tar.gz >>/dev/null

cd pip.10.0.1

python3 setup.py build

python3 setup.py install

注意，这里是安装到python3中，默认是安装到python所链接的具体版本中。

3.python安装

这种方式，直接通过python安装，与脚本安装类似，但是这个安装的是当前python版本所以依赖的pip，可能版本较低，因为内置python版本并不高。

yum upgrade python-setuptools

yum install python-pip
