为什么我不能将pipenv更新到最新版本？

Question

如果我检查我的pipenv版本，它总是显示5.3.5，但我知道有更新的11.0.2版本。如何使用pip更新它？

C:\hello_world>pip search pipenv
dh-pipenv (0.1.1)                  - Shim between dh-virtualenv and pipenv
pipenv-package-requirements (0.2)  - Pipenv tools for requirements.txt
pipenv-tools (0.0.1)               - The missing tools for pipenv.
tox-pipenv (1.3.0)                 - A pipenv plugin for tox
pipenv-to-requirements (0.3.1)     - Generate requirements[-dev].txt from
                                     Pipfile using pipenv
pipenv (11.0.2)                    - Python Development Workflow for Humans.
  INSTALLED: 5.3.5
  LATEST:    11.0.2

安装时，我得到的全部信息是：

这个问题很简单，但主要是为了向你们展示我所看到的。因此，这基本上是填充文本，这样StackOverflow就不会标记出问题主要是代码。请帮帮忙。

升级的正确方式是升级：

pip install --upgrade pipenv
