virtualenvwrapperをEl Capitanにインストールするには？

Question

私はすでにMacにpipとvirtualenvをインストールしましたが、virtualenvwrapperをインストールしようとすると問題に遭遇しました。私はそれを再インストールしようとすると、それは言う：

The directory '/Users/mhcadmin/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.

しかし、私はmkvirtualenv実行したときに、私は次のようなメッセージ

mhcadmin$ mkvirtualenv 

-bash: mkvirtualenv: command not found 

を取得し、私も Installing virtualenv virtualenvwrapper with pip on osx 10.11.1 この記事に従うが、それはうまくいきませんでしたを試してみました。

これは私のbash_profileには次のようになります。

# Python's virtualenvwrapper-RELATED 

export WORKON_HOME=/Users/mhcadmin/.virtualenvs 

source /usr/local/bin/virtualenvwrapper.sh 

と、これは私のbashrcには、次のようになります。

export WORKON_HOME=~/.virtualenvs 

source /usr/local/bin/virtualenvwrapper.sh

私は

which virtualenvwrapper.sh 

その後、私はちょうどコピーを使用してvirtualenvwrapper.shを見つけた後

open -a Finder /usr/local/bin 

を入力して、USR/local/binにアクセスできることが分かっvirtualenvwrapper.shをusr/local/binにコピー
