安装tqsdk没有任何问题，但安装tqsdk2却出现了怪异的现象，导致无法安装tqsdk2

1、使用带 -i 参数的安装命令：

pip install tqsdk2 -i https://pypi.tuna.tsinghua.edu.cn/simple some-package -trusted-host=pypi.tuna.tsinghua.edu.cn

Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple
ERROR: Could not find a version that satisfies the requirement tqsdk2 (from versions: none)
ERROR: No matching distribution found for tqsdk2

2、使用不带 -i 参数的安装命令：

pip install tqsdk2 https://pypi.tuna.tsinghua.edu.cn/simple some-package -trusted-host=pypi.tuna.tsinghua.edu.cn

换了还几个不同的国内镜像源，都出现了相同的错误提示，导致tqsdk2始终无法安装！
