Linux下怎么安装ipython

一、通过压缩包安装ipython

1、下载IPython安装包

$ wget https://files.pythonhosted.org/packages/82/0a/146b0f0f1ddf13ab8682aed5c5a42250cddf1082e193ec95b50b03b9f791/ipython-7.3.0.tar.gz

2、安装IPython

[root@localhost ~]# tar xf ipython-7.3.0.tar.gz[root@localhost ~]# cd ipython-7.3.0[root@localhost ipython-7.3.0]# pwd/root/ipython-7.3.0[root@localhost ipython-7.3.0]# python3 setup.py install

#前提已安装python3， #Linux系统安装Python3 见 : http://www.cnblogs.com/chengd/p/7078498.html

3、通过pip安装ipython所有缺失模块，直至ipython运行成功

[root@localhost ipython]# ipythonTraceback (most recent call last): File "/usr/local/bin/ipython", line 4, in    from IPython import start_ipython File "/usr/local/lib/python3.7/site-packages/IPython/__init__.py", line 54, in    from .core.application import Application File "/usr/local/lib/python3.7/site-packages/IPython/core/application.py", line 23, in    from traitlets.config.application import Application, catch_config_errorModuleNotFoundError: No module named 'traitlets'

#运行ipython是提示缺少’traitlets’模块； #安装提示一步步通过pip安装缺失模块

[root@localhost ipython]# pip install 'traitlets'Collecting traitlets Downloading https://files.pythonhosted.org/packages/93/d6/abcb22de61d78e2fc3959c964628a5771e47e7cc60d53e9342e21ed6cc9a/traitlets-4.3.2-py2.py3-none-any.whl (74kB)   100% |████████████████████████████████| 81kB 100kB/sRequirement already satisfied (use --upgrade to upgrade): enum34; python_version == "2.7" in /usr/lib/python2.7/site-packages (from traitlets)Requirement already satisfied (use --upgrade to upgrade): six in /usr/lib/python2.7/site-packages (from traitlets)Collecting ipython-genutils (from traitlets) Downloading https://files.pythonhosted.org/packages/fa/bc/9bd3b5c2b4774d5f33b2d544f1460be9df7df2fe42f352135381c347c69a/ipython_genutils-0.2.0-py2.py3-none-any.whlRequirement already satisfied (use --upgrade to upgrade): decorator in /usr/lib/python2.7/site-packages (from traitlets)Installing collected packages: ipython-genutils, traitletsSuccessfully installed ipython-genutils-0.2.0 traitlets-4.3.2You are using pip version 8.1.2, however version 19.0.3 is available.You should consider upgrading via the 'pip install --upgrade pip' command.

升级pip

[root@localhost ipython]# pip install --upgrade pipCollecting pip Downloading https://files.pythonhosted.org/packages/d8/f3/413bab4ff08e1fc4828dfc59996d721917df8e8583ea85385d51125dceff/pip-19.0.3-py2.py3-none-any.whl (1.4MB)   68% |█████████████████████▉          | 921kB 8.5kB/s eta 0:00:51   100% |████████████████████████████████| 1.4MB 73kB/sInstalling collected packages: pip Found existing installation: pip 8.1.2   Uninstalling pip-8.1.2:     Successfully uninstalled pip-8.1.2Successfully installed pip-19.0.3

二、直接通过pip安装ipython
