<p>上节课我们安装好了虚拟环境，这节课我们来教会大家基本的使用，关于其他使用命令，日常不常用的，我就不讲解了，讲多了大家也记不住。</p>
|
||
<p>接着上节课我们打开了一个cmd窗口对吧，目前还是没有任何虚拟环境的。</p>
|
||
<h3 id="创建虚拟环境"><a name="创建虚拟环境" class="anchor-navigation-ex-anchor" href="#创建虚拟环境"><i class="fa fa-link" aria-hidden="true"></i></a>创建虚拟环境</h3>
|
||
<pre class="language-"><code class="lang-powershell">mkvirtualenv test
|
||
</code></pre>
|
||
<p>回车，就创建好了，你可以使用<code>workon</code>查看到生成了一个名为<code>test</code>的虚拟环境，并且直接激活进入了该虚拟环境。</p>
|
||
<a href="assets/6-10-1.jpg" data-lightbox="ac0856dc-2419-4e65-a17d-2a7dcbf2c291" data-title="图6-10-1 创建test虚拟环境"><figure id="fig1.8.10.1"><img src="assets/6-10-1.jpg" alt="图6-10-1 创建test虚拟环境"><figcaption>图6-10-1 创建test虚拟环境</figcaption></figure></a>
|
||
<p>这里<code>mkvirtualenv</code>就是创建新的虚拟环境的命令，你记住<code>mk</code>即可，应该是英文单词<code>make</code>制造。后面跟随的是空格和虚拟环境的名字，它会在之前的<code>WORKON_HOME</code>路径下创建一个以这个名字命名的文件夹，所以你的名字也别太花哨了，文件夹名不支持的字符不要作为名字哦~比如我们这里就是名字为<code>test</code>，到资源管理器中查看该路径，确实该文件夹已经创立。</p>
|
||
<p>这种命令的写法默认会使用你<code>当前的系统python的版本</code>创建一个虚拟环境。</p>
|
||
<p>像这种创建方法你可以直接进入到新虚拟环境中，大家可以看到在上图中命令提示符最后一行的最左侧多了<code>(test)</code>这样的标识，这就是已进入虚拟环境的标志。在虚拟环境进入后，我们可以输入<code>python</code>进入当前虚拟环境版本的<code>python shell</code>，也可以使用<code>python py文件名</code>或<code>pip</code>命令来使用虚拟环境。这时你若使用<code>pip install 包名</code>命令，安装的包只会存在于虚拟环境，不会安装到系统的python环境，这就能让项目的三方包环境非常整洁干净，未来你需要看一下这个项目用了哪几个三方包，版本号是多少的时候就会极其方便。</p>

|
||
<p>[!note]</p>
|
||
<p>如果你感兴趣，可以到虚拟环境的存放目录，看一下虚拟环境跟普通已安装好的python有什么区别。</p>
|
||
<p>可以发现，其实就是将已安装的python进行虚拟化，复制一份，文件夹也做了一些优化，让它可以作为独立环境运行。</p>

|

<pre class="language-"><code class="lang-powershell">deactivate

|
||
<p><code>activate</code>是激活的意思，加上否定前缀就是不激活咯，就是退出虚拟环境了，而<code>activate</code>也是一个激活的命令，后面我们会讲到。</p>

|

<p>如图，命令提示符最后一行的最左侧恢复了正常。</p>

<h3 id="激活或切换虚拟环境"><a name="激活或切换虚拟环境" class="anchor-navigation-ex-anchor" href="#激活或切换虚拟环境"><i class="fa fa-link" aria-hidden="true"></i></a>激活或切换虚拟环境</h3>
|
||
<p>如上面的截图例子所示，我们的当前目录在<code>C:\Users\xueshanlinghu</code>这个路径下，我们可以切换当前工作目录到你要激活的那个虚拟环境目录下的<code>Scripts</code>文件夹下，如<code>E:\ProgramFiles\virtualpython\test\Scripts</code>，在这里我们可以运行</p>
|
||
<pre class="language-"><code class="lang-powershell">activate
|
||
</code></pre>
|
||
<p>即可激活虚拟环境。</p>
|
||
<p>但我一般很少这样操作。还记得我们上节课学习过的可以通过<code>workon</code>命令查看当前有多少个虚拟环境吗，它会把所有虚拟环境的名字罗列出来。你如果知道你要进入哪个虚拟环境的名字，可以在任意工作目录下输入命令：</p>
|
||
<pre class="language-"><code class="lang-powershell">workon test
|
||
</code></pre>
|
||
<a href="assets/6-10-3.jpg" data-lightbox="3c220604-7643-491f-84cd-5ef363d3b9e6" data-title="图6-10-3 workon激活虚拟环境test"><figure id="fig1.8.10.3"><img src="assets/6-10-3.jpg" alt="图6-10-3 workon激活虚拟环境test"><figcaption>图6-10-3 workon激活虚拟环境test</figcaption></figure></a>
|
||
<p>这样我们可以更轻松进行虚拟环境的激活了，<code>test</code>这个虚拟环境名你可以换成你的。通常推荐大家这样用。</p>
|
||
<p>顺便，我们来看一下<code>pip list</code>和<code>pip --version</code>的运行效果：</p>
|

<p>[!question]</p>

</blockquote>
|
||
<p>那就删除呗。</p>
|
||
<p>你可以到虚拟环境的文件夹将该虚拟环境文件夹直接删除即可。</p>
|
||
<p>我个人一般会用命令删除：</p>
|
||
<pre class="language-"><code class="lang-powershell">rmvirtualenv test
|
||
</code></pre>
|
||
<p>这样就可以把<code>test</code>这个虚拟环境删除了。其实就是前面加了<code>rm</code>，应为<code>remove移除</code>的意思，很好理解和记忆。</p>

|
||
<p>这里我们的系统环境python是3.8.2版本，我们拿安装python2.7.18和python3.6.6版本的虚拟环境为例跟大家做讲解，其他的可以举一反三。</p>
|
||
<p>安装包下载（我也会在课程中提供给大家，这里均为64位的安装包为例）：</p>
|
||
<ul>
|
||
<li>python3.6.6：<a href="https://www.python.org/ftp/python/3.6.6/python-3.6.6-amd64.exe" target="_blank">https://www.python.org/ftp/python/3.6.6/python-3.6.6-amd64.exe</a></li>
|
||
<li>python2.7.18：<a href="https://www.python.org/ftp/python/2.7.18/python-2.7.18.amd64.msi" target="_blank">https://www.python.org/ftp/python/2.7.18/python-2.7.18.amd64.msi</a></li>
|
||
</ul>
|

<h4 id="python366虚拟环境创建"><a name="python366虚拟环境创建" class="anchor-navigation-ex-anchor" href="#python366虚拟环境创建"><i class="fa fa-link" aria-hidden="true"></i></a>python3.6.6虚拟环境创建</h4>
|
||
<p>安装很简单，跟之前学习的差不多，需要注意的是，不要选择添加到环境变量就可以了。</p>
|
||
<a href="assets/6-10-6.jpg" data-lightbox="38563aab-59e3-4296-ae43-cad262fa156a" data-title="图6-10-6 python3.6.6安装"><figure id="fig1.8.10.6"><img src="assets/6-10-6.jpg" alt="图6-10-6 python3.6.6安装"><figcaption>图6-10-6 python3.6.6安装</figcaption></figure></a>
|
||
<p>这里比如我安装在<code>E:\ProgramFiles\virtualpython\purepython\python3.6.6</code>目录下。</p>
|
||
<p>安装完成后复制一份该文件夹到当前目录下。复制后，就可以到系统程序与功能-卸载或更改程序那里，将python3.6.6版本卸载掉了，这样可以让系统不那么乱，更绿色。卸载后，将刚才备份的文件夹重命名跟复制前<code>python3.6.6</code>一样。</p>
|
||
<p>完成后即可在cmd输入命令创建了，例如：</p>
|
||
<pre class="language-"><code class="lang-powershell">mkvirtualenv <span class="token operator">-</span>p <span class="token string">"E:\ProgramFiles\virtualpython\purepython\python3.6.6\python.exe"</span> py36
|
||
mkvirtualenv <span class="token operator">--</span>python <span class="token string">"E:\ProgramFiles\virtualpython\purepython\python3.6.6\python.exe"</span> py36
|
||
</code></pre>
|
||
<blockquote>
|
||
<p>[!tip]</p>
|
||
<p>上面两种方法均可以创建，任选一种即可，我个人喜欢第一种。-p参数后面跟上你安装的其他版本python的python.exe解释器的绝对路径，如果路径中没有空格可以不加引号，如果有需要加上引号，我建议你都加上就好了。写完后再写上需要创建的虚拟环境名称即可。</p>

|
||
<p>由于安装包是msi的后缀，所以稍微跟python3的有一点点小区别。</p>
|
||
<p>安装时注意点我就不多说了，参考我们之前安装python的时候，需要注意的是不要选择添加到环境变量，默认就是不选的，按默认的就行：</p>
|
||
<a href="assets/6-10-8.jpg" data-lightbox="3a1eccfd-ba90-47a9-ae54-310f9f586730" data-title="图6-10-8 python2.7.18安装"><figure id="fig1.8.10.8"><img src="assets/6-10-8.jpg" alt="图6-10-8 python2.7.18安装"><figcaption>图6-10-8 python2.7.18安装</figcaption></figure></a>
|
||
<p>这里我安装到了<code>E:\ProgramFiles\virtualpython\purepython\python2.7.18</code>这个文件夹下。复制一下这个文件夹。</p>
|
||
<p>接下来这一步很重要，你需要到<code>C:\Windows\System32</code>这个目录，搜索<code>python27.dll</code>这个文件并拷贝到另一个地方备份。</p>
|
||
<p>然后到系统程序与功能-卸载或更改程序那里将python2.7.18版本卸载了，卸载完成后，将刚才复制备份的文件夹修改回<code>python2.7.18</code>这个文件夹名。</p>
|
||
<p>将<code>python27.dll</code>这个文件还原到<code>C:\Windows\System32</code>这个目录。</p>
|
||
<p>这样，绿色版的python2.7.18就制作好了。</p>
|
||
<p>你可以输入命令来创建一个python2.7的虚拟环境了：</p>
|
||
<pre class="language-"><code class="lang-powershell">mkvirtualenv <span class="token operator">-</span>p <span class="token string">"E:\ProgramFiles\virtualpython\purepython\python2.7.18\python.exe"</span> py27
|
||
</code></pre>

|
||
<p>可以看到，确实使用了python2.7.18的版本。</p>
