Errore: il passaggio “brew link” non è stato completato correttamente

Sto cercando di installare node.js tramite Homebrew. Sfortunatamente, ottengo questo errore:

➜ ~ brew install node ==> Downloading http://nodejs.org/dist/v0.8.10/node-v0.8.10.tar.gz ######################################################################## 100.0% ==> ./configure --prefix=/usr/local/Cellar/node/0.8.10 ==> make install ==> Caveats Homebrew installed npm. We recommend prepending the following path to your PATH environment variable to have npm-installed binaries picked up: /usr/local/share/npm/bin Warning: Could not link node. Unlinking... Error: The `brew link` step did not complete successfully The formula built, but is not symlinked into /usr/local You can try again using `brew link node' ==> Summary /usr/local/Cellar/node/0.8.10: 856 files, 13M, built in 103 seconds 

Allora provo a colbind il nodo manualmente …

 ➜ ~ brew link node Linking /usr/local/Cellar/node/0.8.10... Warning: Could not link node. Unlinking... Error: Could not symlink file: /usr/local/Cellar/node/0.8.10/lib/node_modules/npm/scripts/relocate.sh Target /usr/local/lib/node_modules/npm/scripts/relocate.sh already exists. You may need to delete it. To force the link and delete this file, do: brew link -f formula_name To list all files that would be deleted: brew link -n formula_name 

Non ho fortuna, quindi provo forzatamente a colbind il nodo …

 ➜ ~ brew link -f node Linking /usr/local/Cellar/node/0.8.10... Warning: Could not link node. Unlinking... Error: Permission denied - /usr/local/lib/dtrace/node.d 

Non ho dimestichezza con dtrace in ogni senso e ho paura di incasinare le autorizzazioni, quindi ho provato a sudo ..

 ➜ ~ git:(master) sudo brew link -f node Password: Error: Cowardly refusing to `sudo brew link' You can use brew with sudo, but only if the brew executable is owned by root. However, this is both not recommended and completely unsupported so do so at your own risk. 

Ho provato a disinstallare il nodo tramite brew uninstall node e riprovare l’installazione senza fortuna.
