We tried the above but they didn't work in our case because we had two versions of python3 on the systems. One via a normal install a few months back and one via brew (on a Mac). When we discovered that, we downloaded and installed the latest version from python.org and as a result the pip was updated too. Once the pip was installed the sudo pip3 install virturaenv command worked fine.
我们尝试了上述方法，但它们在我们的案例中不起作用，因为我们在系统上有两个版本的 python3。一个通过几个月前的正常安装，一个通过 brew（在 Mac 上）。当我们发现时，我们从 python.org 下载并安装了最新版本，结果 pip 也更新了。安装 pip 后， sudo pip3 install virturaenv 命令工作正常。

If you are using Windows, you have to run cmd as admin.
如果您使用的是 Windows，则必须以管理员身份运行 cmd。
