python安装ta-lib遇到的问题

安装Ta-Lib报错，反馈需要c++库，感觉很麻烦

报错如下：

  note: This error originates from a subprocess, and is likely not a problem with pip.

分析了一通，
说需要以下步骤
以下是解决该问题的一般步骤：

1. 安装C版本的TA-Lib：

1.1 对于Windows用户，可以从非官方的二进制发布页面下载预编译的TA-Lib DLL：https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib

1.2 选择与你Python版本相匹配的.whl文件（比如如果你使用的是Python 3.12的64位版本，则需要下载相应版本的TA_Lib.whl）。

1.3 使用pip安装下载的.whl文件，例如：pip install TA_Lib‑0.4.24‑cp312‑cp312‑win_amd64.whl（请根据实际文件名调整命令）。

2. 设置环境变量（如果需要的话）：

2.1 如果安装了C版本的TA-Lib但仍然遇到问题，可能需要将TA-Lib的bin目录添加到系统的PATH环境变量中，以便Python能够在运行时找到它。

3. 重新尝试安装Python包：

3.1 在确保C版本的TA-Lib已正确安装后，再次尝试通过pip安装TA-Lib Python包。

4. 检查Python和pip是否为最新版本：

4.1 确保你使用的Python和pip是最新的，因为旧版本可能会导致兼容性问题。

5. 确保Visual C++ Build Tools已安装：

5.1 如果你打算从源码编译TA-Lib或任何其他Python扩展，那么你需要安装Visual C++ Build Tools，这是用来编译C/C++代码的工具集。

解决方案

找了下地址 https://github.com/cgohlke/talib-build/
直接下载.whl包

选择python版本对应的版本

执行命令

python.exe -m pip install \xxx\xxxx\ta_lib-0.6.0-cp312-cp312-win_amd64.whl

这样就解决了
