看目录结构好像不是veighna的软件，是在https://github.com/vnpy/vnpy 这里下载的么

dlopen报错是dll读取问题，我估计你使用的是arm芯片的mac，然后通过brew安装的talib和你python的版本不一致。

arm芯片mac默认使用的是arm版本的brew，但anaconda3的arm版本出的比较晚，我估计你的anaconda3应该是x86版本的，所以python也是x86版本的，就会导致不兼容。解决办法可以试试使用x86版本的brew来安装talib试试。

你好，我重新clone了上文网址，安装了x86 brew，并且再装了ta-lib之后，仍然显示
