The problem arises because you haven't the module in your environment, you can install it using <code>pip install PySide2</code>

You used all lower-case letters in your <code>PySide2</code> import statement.

The error message shows that your code imports using lowercase letters instead of mixed case:

<pre><code>NO module named "pyside2"
</code></pre>

You probably installed PySide2 using all lowercase letters, <code>pip install pyside2</code>, but your code must import from: <code>PySide2</code>.

I solved this issue by: 


1. Repairing my Python installation 
2. Deleting the virtual environment 
3. Creating a new virtual environment 
4. Running <code>pip install PySide2</code> in the new virtual environment

I had the same problem and solved it with the following way.
Reference from <a href="https://doc.qt.io/qtforpython/deployment-pyinstaller.html" rel="nofollow noreferrer">Qt for Python &amp; PyInstaller</a>
<blockquote>
Since it has a UI, you use the –windowed option.
The command line to proceed looks like this:
</blockquote>
<pre><code>pyinstaller --name=&quot;MyApplication&quot; --windowed hello.py
</code></pre>
<blockquote>
This process creates two directories: dist/ and build/. The
application executable and the required shared libraries are placed in
dist/MyApplication.
To run the application, go to dist/MyApplication and run the program:
</blockquote>
<pre><code>cd dist/MyApplication/
./MyApplication
</code></pre>

Well there might be one of these two problems:
<ol>
<li>You have not installed PySide2, In that case you can install it using command pip install PySide2</li>
<li>The second is you have installed the Pyside2 but in one installation and trying to use it from another installation, to tackle with this, Create a virtual environment for your project and install all modules in that virtual environment.</li>
</ol>
It's always a good idea to create virtual environment for project it will avoid breaking the base env. It avoid such kind of issues

I am trying to run python file on my terminal and I get the error of &quot;no module named pyside2&quot;
I tried the to run the code which was already answered on similar type of question. But no changes on my side.
ERROR message:
<pre><code>Traceback (most recent call last)
File &quot;xxx-qt.py&quot;, line 31, in &lt;module&gt;
from pyside2 import qtcore
Modulenotfounderror: NO module named &quot;pyside2&quot;
</code></pre>

How do I solve error "no module found named pyside2"?

我试图在我的终端上运行python文件，并得到了错误的“没有模块名为pyside2”的。我试着运行代码，它已经在类似类型的问题上得到了回答。但我这边没有变化。错误信息：Traceback (most recent call last)File "xxx-qt.py", line 31, in <module>from pyside2 import qtcoreModulenotfounderror
