最近我使用pip安装了virtualenvwrapper，现在每次启动终端（我使用Ubuntu16.04）时它都会显示我：
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/premkproject
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/postmkproject
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/initialize
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/premkvirtualenv
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/postmkvirtualenv
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/prermvirtualenv
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/postrmvirtualenv
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/predeactivate
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/postdeactivate
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/preactivate
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/postactivate
virtualenvwrapper.user_scripts creating /home/jorge/.virtualenvs/get_env_details
我怎样才能阻止这些讯息？
