關於Python安裝PyQT5相關庫PyQT5-tools安裝失敗版本不適配的問題

編輯：Python

最近想要用Python做界面程序的開發，研究了下，主流是使用PyQT5相關庫來開發，於是就開始了PyQT5相關庫的安裝。本以為安裝一個庫而已，這不是Python開發者手到擒來的事嗎，so easy啦！

但是，結果卻是，一直報錯安裝不了！！！

在PyCharm集成環境安裝報錯如下：

ERROR: Could not find a version that satisfies the requirement pyqt5-tools (from versions: none)

在終端執行命令執行報錯如下：

一直都是版本不適配的問題。

OK！那就安裝低版本的Python解釋器！

我依次降低了Python解釋器的版本。重復以上操作，還是依舊報錯。。。。

算了吧！

放棄吧！

還是用Java開發用C語言開發吧

。。。

。。。。

。。。。。

還是再努力一下吧，我覺得我悟了

我翻看了很多博客，看到了這樣一個解決方案

我嘗試了一下。我用Python3.6版本的解釋器。我先安裝了 wheel

然後再安裝PyQT5-tools

然後竟然成功安裝了哦！！！

然後開始配置 Qt Designer

配置 PyUIC

配置PyRCC

OK！
測試一下

打開了。

就是這麼完美。

寫個Hello World 試試。

創建一個測試項目

打開新窗口

右鍵代開 Designer

然後創建一個 weidge 窗口。

拖入一個lable顯示標簽

標簽寫 Hello World

保存命名為 HelloWorld.iu

用PyUIC打開保存的文件

生成一個 HelloWorld.py的文件

修改一下mian.py 調用HelloWorld.py

import sys
import HelloWorld
from PyQt5.QtWidgets import QApplication, QMainWindow
if __name__ == '__main__':
app = QApplication(sys.argv)
MainWindow = QMainWindow()
ui = HelloWorld.Ui_Form()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())

執行一下

哦吼。報錯了。
