我已按照以下步骤操作，但仍无法创建本机应用程序

对于MacOS

安装自制软件

/ usr / bin / ruby -e“ $（curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install）” 安装节点

酿造安装节点

安装值班员

酿造守望者

最后安装React Native CLI

npm install -g react-native-cli

使用正在使用

from bs4 import BeautifulSoup
import requests

url = "https://www.webtoons.com/en/comedy/bluechair/ep-366-husk/viewer?title_no=199&episode_no=538"
headers={
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36',
        'Referer' : url
    }

r = requests.get(url, headers = headers)
soup=BeautifulSoup(r.content,'lxml')
imgs=[link['data-url'] for link in soup.select('#_imageList img')]

counter = 0
for img in imgs:
    counter = counter + 1
    filename = 'image' + str(counter) + '.jpg'
    with open(filename, 'wb') as handle:
        response = requests.get(img, stream=True, headers = headers)

        if not response.ok:
            print(response)

        for block in response.iter_content(1024):
            if not block:
                break
            handle.write(block)

创建项目，对吧？

否则，请确保它在您的PATH中。请参阅以下内容：

-bash: react-native: command not found

-bash：react-native：找不到命令mac
