点击子命令问题:测试子命令失败

Question

嗨：我是新来点击的，下面是我测试子命令失败的例子：出于某些原因，我需要保持我的python环境干净，我创建了一个虚拟环境来安装click-in"；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，以便创建一个快捷方式来激活我的虚拟环境。

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

结果是：

> 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，我被困在了群组命令中

> 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脚本没有传递"用户"；python脚本的参数。

# 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
