解决Windows系统下Python不能使⽤export指令的困扰export是linux系统下的指令，在window系统下不能使⽤，很不⽅便，本⽂复现了⼀下export的功能。
问题描述：
'export' 不是内部或外部命令
新建exporttest.py，代码如下：
import argpar
import sys
from pathlib import Path
parr = argpar.ArgumentParr()

parr.add_argument("--path", type=str, default="")
parr.add_argument("--deletepath", type=str, default="")
args = parr.par_args()
# sys.path.append(r'newlib_path')
if __name__ == '__main__':
exportpath = eval(repr(args.path).replace('\\', '\\\\'))
exportpathlist=exportpath.split('AND')
# print(pathlist)

deletepath = eval(repr(args.deletepath).replace('\\', '\\\\'))
deletepathlist = deletepath.split('AND')
filepath=sys.prefix+'\Lib\site-packages\myExportPath.pth'
file = Path(filepath)
if ists():
# print("File doesn't exist, this code will first create one and then add the paths")

print("warning: the path "+path+" already exists")
print("warning: the path "+path+" already exists")

print("The export paths are: \n" + existingPaths)
# print(sys.path)
使⽤⽅法如下：
1、添加⼀条path
指令：
python exporttest.py --path XXXX #XXXX为你需要export的路径
⽰例：他作文
2、 添加多条path，path中间⽤AND连接
指令：
python exporttest.py --path XXXXANDXXXX #XXXX为你需要export的路径⽰例：
3、查看已经添加的path
指令：
python exporttest.py
⽰例：
4、删除⼀条path
指令：
python exporttest.py --deletepath XXXX #XXXX为你需要删除的路径⽰例：
5、删除多条path，同2，中间⽤AND连接
