Suite à la mise à jours … impossible de faire du SVN.

$ svn cleanup
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

La solution :

$ xcode-select --install
xcode-select: note: install requested for command line developer tools

Cela ouvre une fenêtre :

Misère.

La version :

$ svn --version

Première étape, voir les partitions :

$ diskutil list

En lecture seule :

$ brew install ext4fuse
$ sudo mkdir /Volumes/ext4
$ sudo ext4fuse /dev/disk2s7 /Volumes/ext4 -o allow_other

En lecture écriture :
– Ceci ne marche pas ..

$ brew cask install osxfuse
$ sudo mkdir /Volumes/ext4
$ sudo mount -t fuse-ext2 /dev/disk2s7  /Volumes/ext4/
mount: exec /Library/Filesystems/fuse-ext2.fs/Contents/Resources/mount_fuse-ext2 for /Volumes/ext4: No such file or directory

– Ceci marche :

$ sudo dscl . append /Groups/operator GroupMembership $(whoami)
$ sudo dscl . append /Groups/wheel GroupMembership $(whoami)
$ sudo mkdir /Volumes/ext4 $ sudo ext4fuse /dev/disk2s7 /Volumes/ext4

Enfin le mieux est quand même le « sudo su », car le Groupe ne fonctionne pas correctement.
