即使在我自己的PC上运行正常，Node Canvas仍未安装在Heroku构建中。我正在使用nodejs版本12.16.3。我在任何地方都找不到解决方案。
画布是必须的，在Heroku之前，我从未见过此错误。这是Heroku的问题还是我的软件包/软件包锁定文件的问题？

Perhaps you should add the directory containing `pangocairo.pc'
to the PKG_CONFIG_PATH environment variable

预建软件包似乎存在一些问题。它可以根据Node.js版本工作，适用于我的最新版本是14.14.0，因此请尝试在您的package.json

在最新版本https://nodejs.org/en/blog/release/v15.0.1/之后，我的构建从Node v14.14.0切换到v15.0.1之后，我遇到了类似的问题
