At a glance it looks like you need admin permissions to install packages on your system. Try starting pip as admin or your OS equivalent.
乍一看，您似乎需要管理员权限才能在系统上安装软件包。尝试以管理员或您的操作系统等效身份启动 pip。

Your account does not have write access to this directory?.
您的帐户没有此目录的写权限？。
If the installation directory is a system-owned directory, you may need to sign in as the administrator or "root" account.
sudo pip install virtualenvIf you do not have administrative access to this machine, you may wish to choose a different installation directory, preferably one that is listed in your
PYTHON_PATHenvironment variable.easier way: change that dir permission:
chmod +a 'user:YOUR_USER_NAME allow add_subdirectory,add_file,delete_child,directory_inherit' /Library/Python/2.7/site-packages
如果安装目录是系统拥有的目录，您可能需要以管理员或“root”帐户登录。
sudo pip install virtualenv如果您没有对这台机器的管理访问权限，您可能希望选择不同的安装目录，最好是在您的
PYTHON_PATH环境变量中列出的目录。更简单的方法：更改该目录权限：
chmod +a 'user:YOUR_USER_NAME allow add_subdirectory,add_file,delete_child,directory_inherit' /Library/Python/2.7/site-packages

You don't have permission to edit the system-wide version of this library. Try using sudo:
您无权编辑此库的系统范围版本。尝试使用sudo：
sudo pip install --upgrade virtualenv
