Could not install packages due to an EnvironmentError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\LENOVO\\AppData\\Local\\Temp\\pip-req-tracker-hwub07hg\\29e06807d5aed8dd372ea37c64d1e88dc172ee212d473a412d5e638c'
Consider using the `--user` option or check the permissions.

I have run the command through administrator but it didnt workout.

Try to upgrade as Jonny suggested.Restart your computer,Upgrade pip and try installing pandas with Unofficial Windows Binaries for Python Extension Packages or pip install --user <package_name>. Also take a look at PermissionError: [WinError 32] The process cannot access the file because it is being used by another process. Hope it was helpful.
