 | Caveats:
 | \
 |  | krew is now installed! To start using kubectl plugins, you need to add
 |  | krew's installation directory to your PATH:
 |  |
 |  |   * macOS/Linux:
 |  |     - Add the following to your ~/.bashrc or ~/.zshrc:
 |  |         export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"
 |  |     - Restart your shell.
 |  |
 |  |   * Windows: Add %USERPROFILE%\.krew\bin to your PATH environment variable
 |  |
 |  | To list krew commands and to get help, run:
 |  |   $ kubectl krew
 |  | For a full list of available plugins, run:
 |  |   $ kubectl krew search
 |  |
 |  | You can find documentation at

3.根据命令执行结果，配置环境变量

vim ~/.bashrc

# 在末尾新增如下这行
export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"

4.退出当前shell重新打开,然后执行如下命令进行校验

# kubectl krew
