Python 可执行文件在 Windows 上无法识别 10

Question

I recently installed Python 3.6.3 on my device. When I type python in my cmd window, it gives me this error. I do have the PATH in the environment variables. Path Lists . This should normally fix it, but python is still not recognized.

Answer 1

Make sure the path is in your System PATH variable and not in a User PATH variable. After adding the path to the PATH variable, make sure you close and re-open any command prompts so they use the updated PATH.

You should also confirm the path by checking python directly from the folder.

The example below is for the OP's path.

Make sure you use the path specific to your installation:

1. %USERPROFILE%\\AppData\\Local\\Programs\\Python\\Python36

2. %USERPROFILE%\\AppData\\Local\\Programs\\Python\\Python36\\Scripts for access to tools such as PIP

3. %USERPROFILE%\\AppData\\Local\\Programs\\Python\\Launcher

   cd c:\\Python\\Python36-32

   python --version

or using CMD or Powershell on Windows: \\>Python --version should print Python 3.xx where x = version specific numbers.

Answer 2

I had the same problem, due to a stupid decision from Microsoft.

I had another line in my system path variable: C:\\Users\\MyUserName\\AppData\\Local\\Microsoft\\WindowsApps

And windows 10 put there a python.exe file that only redirected me to the python page of the Microsoft Store:

Since this line was above my true python path, typing python in the cmd prompt opened the Microsoft Store... This... is... 100% a stupid decision.

Solution:

Type App execution aliases in the windows 10 search bar, then uncheck the aliases for python.exe and python3.exe . More information here

Answer 3

If still not working, as mentioned above in the answers, then simply move up the path, as shown in the screenshot.

Answer 4

All the answers on StackOverflow about it were obsolete so decided to add this. The path variable that needs to be added is,

C:\Users\Username\AppData\Local\Programs\Python\Python36-32

Note that everyone may have a different Username.

Answer 5

you get this error because the python.exe path has not been added to the System environment variable to do that simply

1. go to the path C:\\Users\\%Username%\\AppData\\Local\\Programs\\Python\\Python37-32 which contains python.exe

2. copy the path and open system environment variables and in the variable section look for variable called Path if not create new variable with Variable Name as Path and value as the copied path

3. once you do that close the window and simply open cmd and type python you should get something like this

Answer 6

If you are working with command prompt and if you are facing the issue even after adding python path to system variable PATH.

Remember to restart the command prompt (cmde.exe).

Answer 7

If you are trying to install new python version python-3.9.6 then click the checkbox of Add Python 3.9 to PATH

Answer 8

For Python 3.6 there are actually 2 path entries. Also it's best to use the %USERPROFILE% rather then hard coding it.

%USERPROFILE%\\AppData\\Local\\Programs\\Python\\Python36 %USERPROFILE%\\AppData\\Local\\Programs\\Python\\Python36\\Scripts

Answer 9

Just Set The Path Variable Correctly As Follows- Go To The Properties Of ThisPc Click Advanced System Settings Click Environment Variables... In System Variables Edit The Path Variable To

C:\\Users\\Username\\AppData\\Local\\Programs\\Python\\Python36-32

Note That, Everyone May have Different UserName.

Answer 10

I too was struggling with this issue, and everything was configured correctly. I installed and setup my system path variables as one would. And everything was fine. Then upon reboot windows would not recognize 'python' as a command as if it were unaware of the path variable. Double checked to confirm everything was still setup correctly (it was).

It only started to work again after I manually browsed to the directory in which python.exe existed, and ran 'python'. After that windows seemed to recognize my path variable and I could call 'python' from where ever need be. Very odd. Figured I'd share in case someone else runs into this.

Answer 11

This happens because the path doesn't exist in environment variables. To fix this :

1. Re-run the installer
2. Choose Modify
3. In optional feature click "Next"
4. In advanced option tick the "Add Python to environment variables"
5. Install
