Question

我正在尝试安装TA-Lib，但我尝试的一切都不起作用。我不知道什么是包裹轮子，为什么错误参考numpy，但我希望有人能帮助我。

我正在使用的：

• Python 3.9.2
• 第21.1.1点

TA-Lib是一个C库。您正试图为它安装一个python包装器，但在安装过程中找不到C库。包装器打印：
setup.py:71: UserWarning: Cannot find ta-lib library, installation may fail.
因此，首先安装C库二进制文件，然后安装python包装器。签出上的"依赖项"部分https://mrjbq7.github.io/ta-lib/install.html
