1.安装pythom（略）

2.安装pycharm（略）

3.安装pyqt5

3.1首先是安装pyqt5

pip install PyQt5

出现错误:

ERROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.
    PyQt5 from https://files.pythonhosted.org/packages/1f/0e/d0390f7ac55c3d4ac041cbdb13fa2b03225a7f8856d52f712e7e398b2208/PyQt5-5.13.2-5.13.2-cp35.cp36.cp37.cp38-none-win32.whl#sha256=14737bb4673868d15fa91dad79fe293d7a93d76c56d01b3757b350b8dcb32b2d:

WARNING: You are using pip version 19.2.3, however version 19.3.1 is available.
You should consider upgrading via the ‘python -m pip install --upgrade pip‘ command.

 输入

python -m pip install --upgrade pip

再输入

pip install PyQt5

安装成功！

3.2 安装Qt工具

pip install PyQt5-tools

出现下面错误

ERROR: Could not find a version that satisfies the requirement PyQt5-tools (from versions: none)
ERROR: No matching distribution found for PyQt5-tools

解决方法如下：

https://pan.baidu.com/s/1GVhquhTe5bgrjGRvUVRloQ 提取码:ain0 
下载后得到一个.whl文件
将上面文件放在‘C:WindowsSysWOW64 目录下

WIN+R输入cmd，回车打开命令提示符:
输入：pip install wheel
然后：pip install PyQt5_Tools-5.7.dev1-py3-none-any.whl
至此就成功安装了pyqt5-tools

安装完成之后先确认一下安装位置，因为之后用的上，正常的话，会在你的python的安装目录下的

pythonx.xLibsite-packages目录下，如图：

3.3 安装安装QtDesigner

然后进入pycharm的File下的settings->Tools->External Tools 点加号，

Name：QtDesigner　　
Program：之前PyQt5-tools目录下的designer.exe文件 如我的E:Python38Libsite-packagesPyQt5-toolsdesignerdesigner.exe
Working directory:$FileDir$

3.4安装PyUIC

进入pycharm的File下的settings->Tools->External Tools 点加号，

Name：PyUIC　　
Program：python目录下的Script下的pyuic5.exe的目录

Argument：
-m
PyQt5.uic.pyuic
$FileName$
-o
$FileNameWithoutExtension$.py

Working directory:$FileDir$

3.5安装PyRCC

进入pycharm的File下的settings->Tools->External Tools 点加号，

Name：PyRCC　　
Program：python目录下的Script下的pyrcc5.exe的目录

Argument：
$FileName$
-o
$FileNameWithoutAllExtensions$.py

Working directory:$FileDir$

over,over,over!
