Linux下安装或升级Python 2.7的操作方法
<p><strong>1.准备编译环境gcc</strong></p>
<p>
<strong>2.去官网下载要安装的对应版本的python的源代码</strong></p>
<p>
下载地址：https://www.python.org/downloads/source/</p>
<p>
你可以选择你要下载的版本，用wget指令来下载相应的源代码</p>
<p>
<strong>3.解压下载的代码包</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_193041">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">tar -zxvf Python-x.x.x.tgz</code>
</div>
<div class="line number2 index1 alt1">
<code class="xhtml plain">cd Python-x.x.x</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
<strong>4.配置</strong></p>
<p>
1)查找configure文件</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_933621">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">find . -name configure</code>
</div>
<div class="line number2 index1 alt1">
<code class="xhtml plain">cd 搜索结果（一般就在Python文件根目录下）</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
2)进行配置</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_165441">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">./configure</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
<strong>5.编译</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_52755">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">make</code>
</div>
<div class="line number2 index1 alt1">
<code class="xhtml plain">make install</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
（如果没有其他特殊需求，安装就到此结束了，输入pythonx.x即可以进入你刚刚安装的python开发环境）</p>
<p>
<strong>6.替换以前的python默认版本（创建新的软连接）</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_193909">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">cd /usr/bin/</code>
</div>
<div class="line number2 index1 alt1">
<code class="xhtml plain">rm -rf python</code>
</div>
<div class="line number3 index2 alt2">
<code class="xhtml plain">ln -s /usr/local/Python-x.x.x/bin/python ./python</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
