Bundling data files with PyInstaller (--onefile)
Newer versions of PyInstaller do not set the env
variable anymore, so Shish's excellent answer will not work. Now the path gets set as sys._MEIPASS
:
def resource_path(relative_path):
""" Get absolute path to resource, works for dev and for PyInstaller """
try:
# PyInstaller creates a temp folder and stores path in _MEIPASS
base_path = sys._MEIPASS
except Exception:
base_path = os.path.abspath(".")
return os.path.join(base_path, relative_path)
pyinstaller unpacks your data into a temporary folder, and stores this directory path in the _MEIPASS2
environment variable. To get the _MEIPASS2
dir in packed-mode and use the local directory in unpacked (development) mode, I use this:
def resource_path(relative):
return os.path.join(
os.environ.get(
"_MEIPASS2",
os.path.abspath(".")
),
relative
)
Output:
# in development
>>> resource_path("app_icon.ico")
"/home/shish/src/my_app/app_icon.ico"
# in production
>>> resource_path("app_icon.ico")
"/tmp/_MEI34121/app_icon.ico"
