python3开发环境安装

1.在linux上使用rpm/yum方式安装

 

2.在linux上使用源码编译安装

安装python3.6

#yum install wget
#yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel

#cd /usr/local/src
#wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
#tar -zxf /usr/local/src/Python-3.6.0.tgz && cd Python-3.6.0

#mkdir /usr/local/python3
# ./configure --prefix=/usr/local/python3.6 --enable-optimizations
make && make altinstall

For example, if you want to install Python 2.7, 3.6, and 3.7 with 3.7 being the
primary version, you would execute ``make install`` in your 3.7 build directory
and ``make altinstall`` in the others.

编译安装python3.7.7 有报错？？？

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_lzma                 _ssl                  _uuid              
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
_abc                  atexit                pwd                
time                                                           


Failed to build these modules:
_ctypes               _xxtestfuzz                              


Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381

编译安装好

 

 

 

# 关键一步，建立链接 
#ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3          # 可直接使用 "python3"
#ln -s /usr/local/python3/bin/pip3.6  /usr/bin/pip3               # 可直接使用 "pip3"

# 最后测试下 
#python3
#pip3

安装ipython模块，提供tab键补全功能

# ln -sv  /usr/local/python3.6/bin/pip3 /usr/bin/
# pip3 install traitlets pygments pexpect pickleshare prompt_toolkit simplegeneric
# /usr/local/python3.6/bin/python3.6 setup.py  build
# /usr/local/python3.6/bin/python3.6 setup.py  install
#ln  -sv  /usr/local/python3.6/bin/python3.6  /usr/bin/python36
#ln  -sv  /usr/local/python3.6/bin/ipython    /usr/bin

 

 

3.在aix上通过二进制方式安装

 

AIX binary packages for Python3 and Python2 are provided by AIXTOOLS for no-charge. The packages are supplied in installp format (not RPM format). There are no pre-requisites other than a recent version of openssl.base.

python在aix平台上的安装包是以installp方式提供的，除了对系统的openssl版本要求新一点以为，没有其的依赖关系.

See the AIXTOOLS wiki for additional details.

The download page for Python 3 is at http://www.aixtools.net/index.php/python3 and the download page for Python 2 is at http://www.aixtools.net/index.php/python2

安装命令

# installp -d aixtools.python3.3.6.5.0.64bit.I -a all
