问题：python 使用pip命令安装第三方包，报错：Fatal error in launcher: Unable to create process using '"d:\worksoft\pyhon\python.exe" "D:\worksoft\python\Scripts\pip.exe" install request': ???????????
解决办法：
1、电脑桌面--Win+R 打开运行，录入：cmd，进入命令界面，录入命令：python -m pip install --upgrade pip
此时命令安装第三方包，即可成功，例如：pip install request (若未成功，报错：ERROR: Could not find a version that satisfies the requirement request
