Windows 10下Python3.10安装scons后命令无法识别问题

在全新Windows 10电脑上安装Python 3.10.7后，执行pip install scons安装Scons，但终端输入scons时持续报错：

C:\Users\tempm>scons
'scons' is not recognized as an internal or external command,
operable program or batch file. 

已将以下路径添加至PATH环境变量，但问题仍未解决：

• C:\Users\tempm\AppData\Local\Programs\Python\Python310\Scripts
• C:\Users\tempm\AppData\Local\Programs\Python\Python310
• C:\Users\tempm\AppData\Local\Programs\Python\Python310\Lib\site-packages\SCons\Script及其所有子目录

查看Python Scripts目录，未找到scons.exe：

Directory of C:\Users\tempm\AppData\Local\Programs\Python\Python310\Scripts

16/09/2022  02:23 PM    <DIR>          .
16/09/2022  02:23 PM    <DIR>          ..
16/09/2022  02:23 PM           107,912 pip.exe
16/09/2022  02:23 PM           107,912 pip3.10.exe
16/09/2022  02:23 PM           107,912 pip3.exe
               3 File(s)        323,736 bytes
               2 Dir(s)  83,683,979,264 bytes free

再次执行pip install scons，提示已安装：

Requirement already satisfied: scons in c:\users\tempm\appdata\local\programs\python\python310\lib\site-packages (4.4.0)
Requirement already satisfied: setuptools in c:\users\tempm\appdata\local\programs\python\python310\lib\site-packages (from scons) (63.2.0)

解决方案 #

通过Python 3.10的pip安装Scons未生成scons.exe，安装Python 3.8并使用其pip安装Scons后，scons.exe成功出现在对应Scripts目录，问题解决。推测可能是Python 3.10存在兼容性问题。

安装Python注意事项 #

安装Python时务必勾选添加至环境变量选项，全新机器更需注意，避免后续配置麻烦。
