解决方法

导入ssl

修改 emsdk.py

引入ssl库

import ssl

修改文件内容

def download_with_urllib(url, file_name):
  u = urlopen(url)

改为如下

def download_with_urllib(url, file_name):
  # 创建不验证SSL证书的上下文
  unverified_context = ssl._create_unverified_context()
  # 将上下文注入urlopen
  u = urlopen(url, context=unverified_context)  # <-- 关键修改

修改upate_node.py

引入ssl库

import ssl

修改文件内容

    print('Downloading: ' + download_url)
    urllib.request.urlretrieve(download_url, filename)

修改成如下

	import ssl

    # 创建未经验证的SSL上下文
    unverified_context = ssl._create_unverified_context()
    print('Downloading: ' + download_url)
    urllib.request.urlretrieve(
        download_url, 
        filename=filename,
        context=unverified_context  # 注入未验证上下文
    )
