Question

我正在尝试安装 TA-Lib，但我尝试的一切都不起作用。我不知道包 wheel 是什么以及为什么错误引用 numpy 但我希望有人能帮助我。

我在用什么：

Python 3.9.2
点 21.1.1

PS C:\Users\ebben> pip install TA-Lib

Using legacy 'setup.py install' for TA-Lib, since package 'wheel' is not installed.

Answer 1

TA-Lib 是一个 C 语言库。您正在尝试为其安装 python 包装器，但在安装过程中找不到 C 库。包装打印：
setup.py:71: UserWarning: Cannot find ta-lib library, installation may fail.
所以，首先，安装 C 库二进制文件，然后安装 python 包装器。在 https://mrjbq7.github.io/ta-lib/install.html
