I recently needed to install pywin32 because of nbconvert. However, when importing win32api, it produces an exception (unable to find some DLL). To fix it, the following path <python>Lib/site-packages/pywin32_system32 must be added to environment variable PATH. But I did not want to do that but I'm using several Python version at the same time so I needed to fix it while running my script which I did below.
def import_pywin32(): """ For the module ``pywin32``, this function tries to add the path to the DLL to ``PATH`` before throwing the exception: ``DLL load failed: The specified module could not be found``. """ try: import win32com except ImportError as e : if "DLL load failed:" in str(e): import os,sys path = os.path.join(os.path.split(sys.executable), "Lib","site-packages","pywin32_system32") os.environ["PATH"] = os.environ["PATH"] + ";" + path try: import win32com except ImportError as ee : dll = os.listdir(path) dll = [os.path.join(path,_) for _ in dll if "dll" in _] raise ImportError("some DLL must be copied:\n" + "\n".join(dll)) from e else : raise e
I hope I'll remember I foudn a way to fix it next time I run into the same exception.
