在Linux SUSE或RedHat上，如何加载Python 2.7

Question

有人可以提供在SUSE和RedHat上安装python 2.7版所需的步骤吗？ 它上面的版本就像2.4，我需要至少2.6才能使我的脚本工作。 所以在安装之后，我可以在xTerm中键入Python并获得Python 2.7命令行界面。

Answer 1

下载源代码和安装说明：

https://www.python.org/download/

注意：您应该检查python 2.7.x的最新版本，因为它经常更新。 目前（2017年10月），最新版本为2.7.14，虽然此评论将变得陈旧，新版本可能会每6个月左右发布一次。

wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz # Download
tar xvfz Python-2.7.14.tgz # unzip
cd Python-2.7.14 # go into directory
./configure
make # build
su # or 'sudo su' if there is no root user
make altinstall

（编辑：make install - >根据Ignacio的评论制作altinstall）。

Answer 2

RHEL 6.2使用（有Python 2.6，我需要Python 2.7.3 ）所以：

$ sudo sh -c 'wget -qO- http://people.redhat.com/bkabrda/scl_python27.repo >> /etc/yum.repos.d/scl.repo'

$ yum search python27

Answer 3

jimbob博士（使用make altinstall ）接受的答案让我大部分都在那里，在/usr/local/bin使用python2.7 ，但我还需要安装一些第三方模块。 好的是easy_install从你运行的Python版本获取其安装位置，但我发现我仍然需要为Python 2.7安装easy_install，否则我会得到ImportError: No module named pkg_resources 。 所以我这样做了：

wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg
sudo -i
export PATH=$PATH:/usr/local/bin
sh setuptools-0.6c11-py2.7.egg
exit

现在我在/ usr / local / bin中有easy_install和easy_install-2.7 ，而前者覆盖了系统的2.6版easy_install，所以我删除了它：

sudo rm /usr/local/bin/easy_install

现在我可以像这样为2.7版本的Python安装库：

sudo /usr/local/bin/easy_install-2.7 numpy

Answer 4

要安装Python 2.7.2，请使用此脚本 - https://github.com/bngsudheer/bangadmin/blob/master/linux/centos/6/x86_64/build-python-27.sh

它还确保您获得sqlite和readline支持。

Answer 5

执行以下命令使yum工作以及python2.7

yum groupinstall -y development
yum groupinstall -y 'development tools'
yum install -y zlib-dev openssl-devel wget sqlite-devel bzip2-devel
yum -y install gcc gcc-c++ numpy python-devel scipy git boost*
yum install -y *lapack*
yum install -y gcc gcc-c++ make bison flex autoconf libtool memcached libevent libevent-devel uuidd libuuid-devel  boost boost-devel libcurl-dev libcurl curl gperf mysql-devel

cd
mkdir srk
cd srk 
wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz
yum install xz-libs
xz -d Python-2.7.6.tar.xz
tar -xvf Python-2.7.6.tar
cd Python-2.7.6
./configure --prefix=/usr/local
make
make altinstall



echo "export PATH="/usr/local/bin:$PATH"" >> /etc/profile
source /etc/profile
mv /usr/bin/python /usr/bin/python.bak
update-alternatives --install /usr/bin/python python /usr/bin/python2.6 1
update-alternatives --install /usr/bin/python python /usr/local/bin/python2.7 2
update-alternatives --config python
sed -i "s/python/python2.6/g" /usr/bin/yum

Answer 6

你必须在RHEL / Centos上安装Python 2.4; 否则，工具开始破碎。 但是你可以进行双重安装; 我在这里谈到这个：

http://thebuild.com/blog/2009/10/17/wordpress-to-djangopostgresql-part-3-installing-apache-python-2-6-psycopg2-and-mod_wsgi/

该职位约为2​​.6，但同样适用于2.7。

Answer 7

关于linux的好处，您仍然可以下载源代码，并且在大多数系统上都有自己编译版本的所有工具。

为了通过键入python从xterm获取python cli，python bin目录必须位于系统路径变量中（ Red Hat示例 ， Suse示例 ）

Answer 8

如果你可以使用2.6， EPEL在python26包中使用RHEL 5，虽然你需要使用python2.6来调用它，因为系统仍然需要python为2.4才能运行。

Answer 9

如果你需要pip和setup工具，请在制作python2.7之前安装openssl和opessl-devl

 yum install openssl-devel

然后按照https://stackoverflow.com/a/4149444/429476进行操作

然后https://pypi.python.org/pypi/setuptools

wget https://bootstrap.pypa.io/ez_setup.py
python2.7 ez_setup.py

然后安装点子

wget https://bootstrap.pypa.io/get-pip.py
python2.7 get-pip.py

然后安装其他软件包pip2.7 install package_name

如果要在Oracle Linux上安装Python 2.7，可以按以下步骤操作：

在/etc/yum.repos.d/public-yum-ol6.repo中启用软件集合。

vim /etc/yum.repos.d/public-yum-ol6.repo

[public_ol6_software_collections] 
name=Software Collection Library release 1.2 packages for Oracle Linux 6 
(x86_64) 
baseurl=[http://yum.oracle.com/repo/OracleLinux/OL6/SoftwareCollections12/x86_64/][1] 
    gpgkey=file:[///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle][2] 
    gpgcheck=1 
    enabled=1 <==============change from 0 to 1

在对yum存储库进行此更改后，您只需运行yum命令即可安装Python：

yum install gcc libffi libffi-devel python27 python27-python-devel openssl-devel python27-MySQL-python

使用跟随变量编辑bash_profile：

vim ~/.bash_profile
PATH=$PATH:$HOME/bin:/opt/rh/python27/root/usr/bin export PATH
LD_LIBRARY_PATH=/opt/rh/python27/root/usr/lib64 export LD_LIBRARY_PATH
PKG_CONFIG_PATH=/opt/rh/python27/root/usr/lib64/pkgconfig export PKG_CONFIG_PATH

现在你可以使用python2.7和pip来安装Python模块：

/opt/rh/python27/root/usr/bin/pip install pynacl
/opt/rh/python27/root/usr/bin/python2.7 --version

Answer 11

如果在./configure阶段出现错误

configure：error：在`/home//Downloads/Python-2.7.14'中：configure：错误：在$ PATH中找不到可接受的C编译器

然后尝试这个。

安装python时在$ PATH中找不到可接受的C编译器
