Therefore, I switched the active developer path to latest Xcode App installed using: sudo xcode-select -switch /Applications/Xcode.appĪnd everything worked like a charm automatically.At last year's Worlwide Developer's Conference (WWDC), Apple announced to Mac app developers that macOS High Sierra 'will be the last macOS release to support 32-bit apps without compromise.' Now, in the macOS High Sierra 10.13.4 beta, Apple is notifying users of the impending change, too. xcrun: error: active developer path ('/Applications/Xcode-beta.app/Contents/Developer') does not exist Active Developer path was still pointing to Old version of Xcode that I had already deleted. Then I tried to check the version of Clang using: clang -versionĪnd the response lead me to the real problem i.e. Therefore, when I tried installing CLion for C++ development and configuring it, CMake gave me error And Updating Command Line Tool didnt work for me: softwareupdate -i 'Command Line Tools (macOS Mojave version 10.14.3) for Xcode-10.3'Īnd showed me this response in terminal Software Update ToolĬommand Line Tools (macOS Mojave version 10.14.3) for Xcode-10.3: No such update The real problem was, when I installed the Xcode 10.3, I deleted the ' Xcode-beta.app' first and then installed the new version.

I faced similar problem on MacOS Mojave version 10.14.3 with Xcode 10.3 installed. It seems that the problem was that the new version of the tools are installed to a different directory, and xcode-select -r is not clever enough to find the latest version. Now, sudo xcode-select -p returns /Library/Developer/CommandLineTools/. But xcode-select -install said the command line tools were already installed. sudo rm -rf /Applications/Xcode.appĭeleted version 8 of the tools.

Xcode-select -p returned /Applications/Xcode.app/Contents/Developer, and clang -version reported an installation directory under there. xcode-select -r and rebooting didn't solve this issue. But clang -version still gave 8.0.0 as the version number. The App Store didn't suggest this upgrade, and neither did softwareupdate -list. I wanted to upgrade the command line tools from version 8 to 9. Hopefully it'll help someone (and it'll surely help me next time I run into the same issue).

I'm going to answer a slightly different question here, because this question came up when I searched for a solution to my problem.

High sierra xcode version
