+
+Let me guess, you ran 
+```
+python -m venv .venv
+```
+and then 
+```
+source .venv/bin/activate
+```
+to use your newly created enviroment and got this:
+
+```bash
+.venv/bin/activate (line 48): Unsupported use of '='. In fish, please use 'set _OLD_VIRTUAL_PATH "$PATH"'.
+_OLD_VIRTUAL_PATH="$PATH"
+^~~~~~~~~~~~~~~~~~~~~~~~^
+from sourcing file .venv/bin/activate
+source: Error while reading file '.venv/bin/activate'
+```
+
+Well there's a pretty easy solution for that! Thing is, there's multiple activate scripts within the _/bin/_ folder on your virtual enviroment.
+
+```bash
+ls .venv/bin/
+Activate.ps1   activate.csh   pip*           pip3.12*       python3@
+activate       activate.fish  pip3*          python@        python3.12@
+```
+
+There it is! An activate script wrriten in fish. So while in fish just use that.
+
+```bash
+source .venv/bin/activate.fish
+```
+
+However, there is even a better way we can activate the virtual enviroment. By adding an _alias_.
+
+```bash
+alias -s myvenv="source $HOME/.venv/venvname/bin/activate.fish"
+```
