Hi @kylefelipe, so far we haven't added support for fish shell to the install/export scripts. These scripts are tested with bash only at the moment. If you are familiar with this shell and if you can send a PR to make the script compatible with fish, we will merge it. Otherwise we will treat this issue as a feature request for fish support.

I used bass so source export.sh.
Install bass using fisherman, then run
$ bass source export.sh

How should I call bass if I installed with env IDF_TOOLS_PATH=/opt/espresiff ./install.sh?

UPDATE: I am upgrading from fish 3.0.2 to fish 3.1 which supports FOO=bar syntax for passing variables to individual commands. See https://github.com/fish-shell/fish-shell/pull/6287
