编译ta-lib出错。 error LNK2001，感觉是VS2022版本太高，这个选择什么版本比较好？

[richardhuo]

我觉得应该要降VS版本试试

VS 降版本到2019 community也是同样错误

https://github.com/mrjbq7/ta-lib/issues/241 应该是这个问题，可以参考一下哈

的确，重新 nmake 了一下就link 完成了。

非常感谢！

Thanks for the above discussion. I'm facing the same problem and tried running nmake but ta-lib still can't be installed through pip method. So is there anything else I need to do?

[mmk909]

looks like the ta-lib binding is basing on vs2015, so higher version may cause this problem, after using the .obj files build by old version, it was fixed. 看起来 TA-Lib 绑定是基于 VS2015 的，所以更高版本可能会引起这个问题，使用由旧版本构建的 .obj 文件后，问题得以解决。

talib installation instruction for linux:

1. download talib source file, someting like ta-lib.x.x.tar.gz
2. unzip the file: tar -xzf ta-lib.x.xtar.gz
3. go to the unzip folder: cd ta-lib- ./configure make sudo make install

python setup.py install
