运行时错误：找不到Freetype库

Question

我在python 3.7.2和Windows 10上运行Glumpy。即使通过pip安装，我仍然会收到此错误。

Traceback (most recent call last):
  File "C:\Users\algeb\Downloads\Animoji-Animate-master\animate.py", line 3, in <module>
    from glumpy import app, gloo, gl

    raise RuntimeError('Freetype library not found')
RuntimeError: Freetype library not found

Answer 1

根据上面的评论中的讨论，问题似乎是Glumpy需要freetype包，这需要安装FreeType库。您可以下载FreeType的Windows二进制文件，例如here。确保下载.dll以获得正确的平台（在您的情况下，现在看起来似乎是64-Bit）。下载完成后，将.dll放在计算机上的某个位置，并将路径添加到PATH环境变量所在的目录中。然后freetype包应该能够找到它。更详细的安装说明可以在freetype包Readme中找到。
