pip3: command not found

I want to install TensorFlow following these instructions: https://web.archive.org/web/20170627102751/https://www.tensorflow.org/versions/r0.12/get_started/os_setup#pip_installation But when I try this code on terminal, it returns an error. $ sudo pip3 install --upgrade $TF_BINARY_URL sudo: pip3: command not found So I installed Homebrew and tried to uninstall and reinstall python3-pip, but didn't work. MakotonoMacBook-ea:~ makotomiyazaki$ brew uninstall python3-pip Error: No such keg: /usr/local/Cellar/python3-pip MakotonoMacBook-ea:~ makotomiyazaki$ brew install python3-pip Error: No available formula with the name "python3-pip" ==> Searching for a previously deleted formula... Warning: homebrew/core is shallow clone. To get complete history run: git -C "$(brew --repo homebrew/core)" fetch --unshallow What should I do for getting pip3? My OS is macOS High Sierra, and I have Python 3.6.2 already installed. EDIT: I tried python3 -m pip and what's returned was this: The directory '/Users/makotomiyazaki/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag. The directory '/Users/makotomiyazaki/Library/Caches/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag. You must give at least one requirement to install (see "pip help install") I also tried which pip3, but just I don't know if it worked... MakotonoMacBook-ea:~ makotomiyazaki$ sudo which pip3 install --upgrade $TF_BINARY_URL /usr/bin/install
You would need to install pip3. On Linux, run first sudo apt update. Then the command would be: sudo apt install python3-pip On Mac, using brew, first brew install python3 Then brew postinstall python3 Try calling pip3 -V to see if it worked.
