title: ModuleNotFoundError: No module named 'tkinter' / PyCharm
body: <p>I am trying to run this code in pycharm:</p>
  
  <pre><code>import tkinter as tk
  
  root = tk.Tk()
  
  w = tk.Label(root, text="Hello, world!")
  w.pack()
  
  root.mainloop()
  </code></pre>
  
  <p>However it always gives me the following errror: </p>
  
  <pre><code>Traceback (most recent call last):
    File "/home/nils/PycharmProjects/rfid/first_test.py", line 1, in &lt;module&gt;
      import tkinter as tk
  ModuleNotFoundError: No module named 'tkinter'
  </code></pre>
  
  <p>If I use the same exact code in IDLE, it works perfectly. I just can not figure out how to install/import tkitner (through the project interpreter didnt work). I am using python 3.7 and the newest Linux Mint.</p>
  
  <p>If you could provide me some hints or a solution, it would be very much appreciated :D</p>
  
  <p>Thanks!</p>
  
  <p>Edit: Typing in " import tkinter " in the IDLE shell works fine, however typing in the same in the PyCharm console produces the error above...</p>
  
  <p>Edit2: I solved the problem by completly uninstalling pycharm and installing it again.</p>
