Could not find a version that satisfies the requirement json (from versions: none)

根据提供的引用内容，当出现"Could not find a version that satisfies the requirement"的报错时，可以尝试将pip源切换到国内的源以解决该问题。这可以通过使用以下命令在终端中执行来完成：pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/

如果切换源后仍然出现新的报错"Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘SSLError(SSLEOFError(8, ‘EOF occurred in violation of protocol (_ssl.c:852)’),)’: /simple/six/ Could not fetch URL https://pypi.org/simple/six/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host=‘pypi.org’, port=443): Max retries exceeded with url: /simple/six/ (Caused by SSLError(SSLEOFError(8, ‘EOF occurred in violation of protocol (_ssl.c:852)’),)) - skipping Could not find a version that satisfies the requirement"，则可能需要升级pip。可以使用以下命令在终端中执行升级pip：python.exe -m pip install --upgrade pip

至于您提到的"Could not find a version that satisfies the requirement json (from versions: none)"的问题，可能是因为您正在尝试安装的json包没有与当前Python环境兼容的版本。建议您尝试使用具体的版本号来安装json包，例如：pip install json==2.0.9，其中2.0.9是一个示例版本号，您可以根据实际情况进行更改。
