brew install pkg-config
注意到： pkg-config: command not found
这个报错，是说操作系统上少了这个命令。参考 Can't install rmagick, pkg-config: command not found
这篇文章。（对于macos系统来说）,主要是执行一下命令：
brew uninstall pkg-config brew install pkg-config brew unlink pkg-config && brew link pkg-config 复制代码
详细执行过程记录：

记得把pkg-config的路径添加到.bash_profile到path中：
export PKG_CONFIG_PATH = /usr/local/Cellar/pkg-config/0.29.2/ export PATH=$PKG_CONFIG_PATH/bin:$PATH 复制代码
再尝试 npm i canvas 报错信息

brew install cairo
参考这篇文章 npm install canvas简明指南
注意到： to the PKG_CONFIG_PATH environment variable No package 'cairo' found
这个报错，cairo可以通过homebrew安装,详细记录如下：

再次安装canvas，成功了。
注意
值得注意的是：我这里并没有按照 npm install canvas简明指南
所说的去安装 XQuartz
,因为在这之前我通过brew安装了pkg-config。
