通过bat设置环境变量的方式运行pythonocc程序

一直以来，我们都是先通过anaconda安装pythonocc,然后在通过运行pycharm设置开发环境的方式来运行pythonocc的程序。但是我最近发现了pycharm也是通过设置环境变量以使得pythonocc程序得以运行。后来我观察出来他们是设置以下几个环境变量，于是我把他们写成了bat，通过此方法来运行pythonocc,结果肯定是成功的下面我将把过程和内容告诉大家。
需要设置的环境变量如下所示

C:\Users\Administrator\Anaconda3\envs\3Dsource;
C:\Users\Administrator\Anaconda3\envs\3Dsource\Library\mingw-w64\bin;
C:\Users\Administrator\Anaconda3\envs\3Dsource\Library\usr\bin;
C:\Users\Administrator\Anaconda3\envs\3Dsource\Library\bin;
C:\Users\Administrator\Anaconda3\envs\3Dsource\Scripts;
C:\Users\Administrator\Anaconda3\envs\3Dsource\bin;
C:\Users\Administrator\Anaconda3\condabin;

运行过程如下所述：

1.新建一个记事本取名为init.bat 里面内容如下

@echo off
cd /d %~dp0
rem 你自己安装anaconda目录来写
set path=C:\Users\Administrator\Anaconda3\envs
rem 你的pythonocc安装环境的名称
set parameter0=3Dsourceset parameter1=\Library\mingw-w64\bin
set parameter2=\Library\usr\bin
set parameter3=\Library\bin
set parameter4=\Scripts
set parameter5=\bin
set parameter6=\Lib\site-packages\PyQt5\Qt5\plugins\platformsset path0=%path%%parameter0%
set path1=%path0%%parameter1%
set path2=%path0%%parameter2%
set path3=%path0%%parameter3%
set path4=%path0%%parameter4%
set path5=%path0%%parameter5%
set path6=%path0%%parameter6%set PATH=%PATH%;%path0%
set PATH=%PATH%;%path1%
set PATH=%PATH%;%path2%
set PATH=%PATH%;%path3%
set PATH=%PATH%;%path4%
set PATH=%PATH%;%path5%
set QT_QPA_PLATFORM_PLUGIN_PATH=%path6%echo %PATH%python core_classic_occ_bottle.py

2.新建一个记事本取名为start.bat 里面内容如下

start init.bat

3.start.bat所在文件夹下新建一个名字为core_classic_occ_bottle.py的python文件其内容如下
