For installing virtualenv, you'll have to either install it using pip as mentioned in the answer by woozyking or you'll have to do something like this:
要安装 virtualenv，您必须使用 woozyking 的答案中提到的 pip 安装它，或者您必须执行以下操作：
$ curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.9.1.tar.gz
$ tar xvfz virtualenv-1.9.1.tar.gz
$ cd virtualenv-1.9.1
$ [sudo] python setup.py install
The command which you have used can be used to create a virtualenv. I would recommend you go through these small videos on virtualenv and virtualenvwrapper to get a better understanding:

There is an other way to install Python packages.
1: download the package, you want
2: open commander (press the win start-button and search for cmd)
3: cd into the folder where you downloaded your package
4: type: "python setup.py install"
还有另一种安装 Python 包的方法。

Since I got the same error as mentioned in the question inspite of installing with:
由于我在安装时遇到了与问题中提到的相同的错误：
pip install virtualenv
I would like to add a few points, that might also help someone else solve the error in a similar way as me. Don't know if that's the best way, but for me nothing else helped.
我想补充几点，这也可能帮助其他人以与我类似的方式解决错误。不知道这是否是最好的方法，但对我来说没有其他帮助。
