使用 tqsdk 已经可以稳定盈利了，但 tqsdk2 还是始终安装不上

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

3、使用带 -U -i 参数的安装命令：

pip install tqsdk2 -U -i https://pypi.tuna.tsinghua.edu.cn/simple –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

换了好几个不同的国内镜像源，都出现了相同的错误提示，导致tqsdk2 还是始终无法安装。不知是什么原因？

望能尽快解决 tqsdk2 的安装问题。
