<p><strong>安装pyenv</strong>:</p>
<p>为了安装pyenv方便，作者开发了另一个项目：pyenv-installer来帮助广大劳苦大众安装pyenv；</p>
<p>pyenv：<a href="https://github.com/yyuu/pyenv/" target="_blank">https://github.com/yyuu/pyenv/</a></p>
<p>pyenv-installer：<a href="https://github.com/yyuu/pyenv-installer" target="_blank">https://github.com/yyuu/pyenv-installer</a></p>
<p>使用pyenv-installer安装pyenv：</p>
<pre><code class="lang-bash">$ curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash
</code></pre>
<p>修改环境变量：</p>
<pre><code class="lang-bash">[sslinux@localhost ~]$ vim ~/.bash_profile <span class="hljs-comment"># 仅对当前用户有效；</span>
<span class="hljs-built_in">export</span> PATH=<span class="hljs-string">"/home/sslinux/.pyenv/bin:<span class="hljs-variable">$PATH</span>"</span>

</code></pre>
<p>更新pyenv：</p>
<pre><code class="lang-bash">pyenv update

<p><strong>卸载pyenv</strong>
pyenv 默认安装在环境变量$PYENV_ROOT所指定的目录下(默认为:~/.pyenv)</p>
<pre><code class="lang-bash">$ rm -rf ~/.pyenv

</code></pre>
<p><strong>local命令:</strong> </p>
<p>local命令切换当前目录及子目录的Python版本，可以通过删除'.python-version'恢复默认Python版本；</p>
<p><strong>global命令:</strong></p>
<p>global切换全局默认Python版本，不建议这么使用；</p>
