创建虚拟环境是指在计算机上创建一个独立的运行环境,其中包含了特定版本的Python解释器和所需的库和依赖项。这样可以避免不同项目之间的冲突,并且可以更好地管理项目的依赖关系。创建虚拟环境可以使用Python自带的venv模块或第三方工具如virtualenv。

Creating a virtual environment at C:\Users\Administrator\.platformio\penv Updating Python package manager (PIP) in a virtual environment
To create a virtual environment at `C:\Users\Administrator\.platformio\penv`, you can use the following command in the command prompt or terminal:
```shell
python -m venv C:\Users\Administrator\.platformio\penv
```
This will create a new virtual environment in the specified directory.
To update the Python package manager (PIP) inside the virtual environment, follow these steps:
1. Activate the virtual environment by running the activation script. In this case, it would be:
```shell
C:\Users\Administrator\.platformio\penv\Scripts\activate
```
2. Once inside the virtual environment, you can upgrade PIP using the following command:
```shell
python -m pip install --upgrade pip
```
This will update PIP to the latest version within the virtual environment.
Remember to activate the virtual environment before working with it and installing or upgrading packages.
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning. 用什么命令关闭这段警告,请给出示例
你可以使用以下命令关闭这段警告:
```
export PIPENV_VERBOSITY=-1
```
这个命令会将环境变量 `PIPENV_VERBOSITY` 的值设置为 `-1`,从而禁用 Pipenv 的警告信息。如果你想永久禁用这个警告,可以将这个命令添加到你的 shell 配置文件中(比如 `~/.bashrc` 或 `~/.zshrc`)。
另外,如果你想在某个特定的命令中禁用这个警告,可以在命令前添加 `PIPENV_VERBOSITY=-1` 前缀,例如:
```
PIPENV_VERBOSITY=-1 pipenv install
```
这个命令会在安装依赖时禁用 Pipenv 的警告信息。
