應該是一個簡單的修復，但顯然不是。我正在嘗試在我的 Ubuntu 18.04 機器上運行 PyQt5。我已經安裝了（或者至少我認為我已經安裝了）Qt 和 PyQt5。我什至能夠成功執行pyuic5 main_window.ui -o MainWindow.py而沒有任何問題。
但是當我運行我的代碼時，我收到以下錯誤：
Traceback (most recent call last):
File "MainWindow.py", line 79, in <module>
from qwt_text_label import QwtTextLabel
ModuleNotFoundError: No module named 'qwt_text_label'
我錯過了什么包裹？我該如何安裝它？是鏈接錯誤還是路徑變數？任何幫助，將不勝感激。
我運行的安裝命令：
python3.8 -m pip install pyqt5
sudo apt-get install qt5-default
這是我的 main_window.ui：

from qwt_text_label import QwtTextLabel
uj5u.com熱心網友回復：
你試過這樣做嗎？
from qwt.text import QwtTextLabel
需要 python QWT。
