When running my build for notarization on Travis CI I get the following error:
xcrun: error: unable to find utility “altool”, not a developer tool or in PATH
You can find complete build output here: https://travis-ci.org/github/trufflesuite/ganache/jobs/663747601#L3825
Complete Travis config here: https://travis-ci.org/github/trufflesuite/ganache/jobs/663747601/config
I've tried running sudo xcode-select -r and sudo xcode-select -s /Applications/Xcode.app per tips found on github and stack overflow (https://stackoverflow.com/a/56617634/160173, https://stackoverflow.com/a/53204124/160173), to no avail.
What am I missing?
My issue was that my Travis config wasn't actually using the root-level osx_image directive of "xcode11.3"; this directive was being ignored due to my use of Travis' include matrix. The correct way to specify the osx_image when using an include matrix is as follows:
matrix:
include:
- os: osx
osx_image: "xcode11.3"
- os: linux
dist: bionic
Once I made this change I didn't need to try the xcode-select solutions linked in my question above.
