title: ERROR: virtualenvwrapper could not create a temporary file name
body: <p>I installed virtualenvwrapper in the following way:</p>
  
  <pre><code>$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  
  $ brew install python
  $ brew install pip
  $ pip install virtualenvwrapper
  
  $  nano ~/.bashrc 
  # Set architecture flags
  export ARCHFLAGS="-arch x86_64"
  # Ensure user-installed binaries take precedence
  export PATH=/usr/local/bin:$PATH
  export PATH=/usr/local/share/python:$PATH
  export WORKON_HOME=~/.virtualenvs
  source /usr/local/bin/virtualenvwrapper.sh
  # Load .bashrc if it exists
  test -f ~/.bashrc &amp;&amp; source ~/.bashrc
  </code></pre>
  
  <p>I got the following error after I executed <code>source .bashrc</code></p>
  
  <pre><code>touch: : No such file or directory
  ERROR: virtualenvwrapper could not create a temporary file name.
  touch: : No such file or directory
