I'm trying to install TA-Lib in VS Code without conda.
In a new terminal VSC and venv I execute:
(trading) D:\CWD>python -m pip install TA-Lib
and getting the output:

Remarks: 1) It's not a problem to install talib with conda. 2) I downloaded required MS C++ package as required. It's seen in Control panel. But probably some settings required for VSC in order to see it. Looks like it's the key point of the problem.

问题的根本在于已安装的visual-cpp-build-tools。
我进行了许多实验和调查，包括msbuild。我几乎达到了目标。

然后我发现了一个带有预编译wheels的网站。 =&gt; 
[&quot;https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib&quot;][1]

来自文章：
[&quot;https://blog.quantinsti.com/install-ta-lib-python/&quot;][2]

所以，从在VS Code中激活的venv中，最终解决方案的语法：

    pip install TA_Lib-0.4.24-cp310-cp310-win_amd64.whl

请注意，文件名与上述网站中提到的Python和操作系统版本相对应。

它有效！

The root of the problem is in the installed visual-cpp-build-tools.
I’ve made a lot of experiments and investigations, including msbuild. I almost reached the goal.

Then I discovered the site with precompiled wheels. =&gt; 
[&quot;https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib&quot;][1]

from the article:
[&quot;https://blog.quantinsti.com/install-ta-lib-python/&quot;][2]

So, from activated venv in VS Code,the syntax of final solution:

    pip install TA_Lib-0.4.24-cp310-cp310-win_amd64.whl

Notice that the file name corresponds to your python and OS versions from the mentioned above site.

It works!
