运行AWS报错：No module named awscli.clidriver

Windows环境安装了AWSCLI，python3暗转了awscli

但是powershell运行aws help 报错：

No module named awscli.clidriver

打开报错源头：

@echo OFF
REM="""
setlocal
set PythonExe=""
set PythonExeFlags=

for %%i in (cmd bat exe) do (
    for %%j in (python.%%i) do (
        call :SetPythonExe "%%~$PATH:j"
    )
)
for /f "tokens=2 delims==" %%i in ('assoc .py') do (
    for /f "tokens=2 delims==" %%j in ('ftype %%i') do (
        for /f "tokens=1" %%k in ("%%j") do (
            call :SetPythonExe %%k
        )
    )
)
%PythonExe% -x %PythonExeFlags% "%~f0" %*
exit /B %ERRORLEVEL%
goto :EOF

这里执行了一段python代码，所以是python执行出错，可以确定的是我安装了awscli，所以是检索包出了错，考虑到我电脑里安装了python2，在系统变量里添加了python2的路径，所以想到会不会aws执行脚本用错了解释器，把本该由python3执行的脚本用python2执行了，删掉系统变量里的python2路径，再执行，好了！！！！！没错，好了。
