This path may not be valid in some cases. For example, on the environment using "virtualenv" python package, both "python.exe" and "hg.bat" are placed in the same directory. In this case, "python.exe" should be found on PATH, because virtualenv activation script puts "python.exe" on the PATH. This patch uses explicit path to "python.exe" only if it exists, and expects that "python.exe" can be found on PATH otherwise. diff --git a/contrib/win32/hg.bat b/contrib/win32/hg.bat --- a/contrib/win32/hg.bat +++ b/contrib/win32/hg.bat @@ -4,9 +4,14 @@ setlocal set HG=%~f0 -rem Use a full path to Python (relative to this script) as the standard Python -rem install does not put python.exe on the PATH... +rem Use a full path to Python (relative to this script) if it exists, +rem as the standard Python install does not put python.exe on the PATH... +rem Otherwise, expect that python.exe can be found on the PATH. rem %~dp0 is the directory of this script -"%~dp0..\python" "%~dp0hg" %* +if exist "%~dp0..\python.exe" ( + "%~dp0..\python" "%~dp0hg" %* +) else ( + python "%~dp0hg" %* +) endlocal
