Deepin下搭建pyqt5开发环境——基于vscode
<p>1.安装pyqt5</p><div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">sudo</span> apt-get <span style="color: rgba(0, 0, 255, 1)">install</span> pyqt5*</pre>
</div>
<p>2.安装QT5开发工具，里面包含了Qt Designer等工具</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">sudo</span> apt-get <span style="color: rgba(0, 0, 255, 1)">install</span> qttools5-dev-tools</pre>
</div>
<p>3.打开vscode，搜索pyqt，安装PYQT Integration插件</p>

<p> </p>
<p>4.点击小齿轮-->扩展设置，对PYQT Integration插件进行设置</p>

<p> </p>
<p>5.在Pyqt-integration › Qtdesigner: Path中，增加QT designer的路径</p>
<div class="cnblogs_code">
<pre>/usr/lib/x86_64-linux-gnu/qt5/bin/designer</pre>
</div>
<p> <img src="https://img2020.cnblogs.com/blog/1183108/202104/1183108-20210430140410751-2037010104.png"></p>
<p>这样完成了对Deepin下pyqt5开发环境的搭建</p>
<p> </p>
<p>可能出现的错误提示：</p>
<p>错误提示1</p>

</div>
<p>错误提示1是使用PYQT Integration插件对.ui文件进行预览时提示的。</p>
<p>错误提示2时python程序导入了pyqt5，运行程序时提示的</p>
<p><strong>这2个错误的原因在于你装了多个pyqt5</strong></p>
<p>一个可能是使用 pip 安装了一个</p>
<div class="cnblogs_code">
<pre>pip3 <span style="color: rgba(0, 0, 255, 1)">install</span> pyqt5</pre>
</div>
<p>另一个可能是使用我上面的命令安装了一个</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">sudo</span> apt-get <span style="color: rgba(0, 0, 255, 1)">install</span> pyqt5*</pre>
</div>
<p>导致不知道用那个xcb</p>
<p><strong>解决方法是将使用pip安装的pyqt5卸载掉</strong></p>
<div class="cnblogs_code">
<pre>pip3 uninstall pyqt5</pre>
</div>
