我们通常使用$ python3 -m venv myvenv创建一个新的virtualenv(此处myvenv是我们的virtualenv的名称).

We usually use $ python3 -m venv myvenv to create a new virtualenv (Here myvenv is the name of our virtualenv).

类似于我的情况，如果您的系统上同时有python3.5和python3.6，那么您可能会遇到一些错误.

Similar to my case, if you have both python3.5 as well as python3.6 on your system, then you might get some errors.

注意::在某些版本的Debian/Ubuntu中，您可能会收到以下错误消息:

NOTE: On some versions of Debian/Ubuntu you may receive the following error:

 The virtual environment was not created successfully because ensure pip is not available.  On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.
      apt-get installpython3-venv  
 You may need to use sudo with that command.  After installing the python3-venv package, recreate your virtual environment. 

在这种情况下，请按照上述说明安装python3-venv软件包:

In this case, follow the instructions above and install the python3-venv package:

$ sudo apt-get install python3-venv

注意::在某些版本的Debian/Ubuntu上启动这样的虚拟环境当前会产生以下错误:

NOTE: On some versions of Debian/Ubuntu initiating the virtual environment like this currently gives the following error:

Error Command: ['/home/wgetdj/WorkPlace/Programming/Python/myvenv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']

要解决此问题，请改用virtualenv命令.

To get around this, use the virtualenv command instead.

$ sudo apt-get install python-virtualenv
$ virtualenv --python=python3.6 myvenv

注意::如果出现类似错误

E:无法找到软件包python3-venv

E: Unable to locate package python3-venv

然后运行:

sudo apt install python3.6-venv
