pipx

在隔离环境中安装和运行Python应用程序

cy解释：pipx可以将应用程序安装在虚拟环境中，但是又不用像conda那样切换虚拟环境，就可以在全局命令行中使用。 比如poetry使用pipx安装后，就可以在命令行中直接使用poetry命令

Install and execute apps from Python packages.

Binaries can either be installed globally into isolated Virtual Environments
or run directly in a temporary Virtual Environment.

Virtual Environment location is C:\Users\cheng\pipx\venvs.
Symlinks to apps are placed in C:\Users\cheng\.local\bin.
Symlinks to manual pages are placed in C:\Users\cheng\.local\share\man.

optional environment variables:
  PIPX_HOME             Overrides default pipx location. Virtual Environments will be installed to $PIPX_HOME/venvs.
  PIPX_BIN_DIR          Overrides location of app installations. Apps are symlinked or copied here.
  PIPX_MAN_DIR          Overrides location of manual pages installations. Manual pages are symlinked or copied here.
  PIPX_DEFAULT_PYTHON   Overrides default python used for commands.
  USE_EMOJI             Overrides emoji behavior. Default value varies based on platform.

options:
  -h, --help            show this help message and exit
  --quiet, -q           Give less output. May be used multiple times corresponding to the ERROR and CRITICAL logging
