点击子命令问题：测试子命令失败

Question

嗨：我是新来单击的，这是我如何未能测试子命令的示例： 由于某些原因，我需要保持 python 环境干净，我创建了一个虚拟环境来安装单击“venv/lib/”

main.py
import click


@click.group()
def cli():
    """This is group command."""
    pass


@click.command()
@click.option('--user', required=True, prompt='your name', help='input your name')
def user(user):
    """This is sub-group command."""
    print(f'Do something here.{user}!')

cli.add_command(user)

if __name__ == '__main__':
    cli()

 

我还创建了一个 shell 脚本来激活虚拟环境。

run_tool.sh
        
# export PYTHONPATH=$PYTHONPATH:'/Volumes/di/Temp/weixintong/wxt_DI_Learn/click_test/venv/lib'
source /Volumes/di/Temp/weixintong/wxt_DI_Learn/click_test/venv/bin/activate
# I tried both activate virtual env and export PYTHONPATH. none of them worked.
cd /Volumes/di/Temp/weixintong/wxt_DI_Learn/click_test
# python3 main.py

然后我在 ~/.zshrc 中创建了一个别名，以便创建激活我的虚拟环境的快捷方式。

nano ~/.zshrc
alias aa=/Volumes/di/Temp/weixintong/wxt_DI_Learn/click_test/run_tool.sh
source ~/.zshrc

结果如下：

> aa                                                                                 at 11:59:04
Usage: main.py [OPTIONS] COMMAND [ARGS]...

  This is group command.

Options:
  --help  Show this message and exit.

Commands:
  user  This is sub-group command.

当我测试子命令时，我被困在组命令中

> aa user                                                                            at 11:59:06
Usage: main.py [OPTIONS] COMMAND [ARGS]...

  This is group command.

Options:
  --help  Show this message and exit.

Commands:
  user  This is sub-group command.

您的 bash 脚本没有将“user”参数传递给 python 脚本。

# Get the first argument after the script name, and use it as command
command="$1"
PYTHONPATH=$PYTHONPATH:'/Volumes/di/Temp/weixintong/wxt_DI_Learn/click_test/venv/lib'
source /Volumes/di/Temp/weixintong/wxt_DI_Learn/click_test/venv/bin/activate
cd /Volumes/di/Temp/weixintong/wxt_DI_Learn/click_test
python3 main.py $command
