安装错误

pip install -r requirements.txt
有下面的错误
ERROR: Could not find a version that satisfies the requirement gm (from -r requirements.txt (line 8)) (from versions: none)
ERROR: No matching distribution found for gm (from -r requirements.txt (line 8))

我先后安装了
brew install imagemagick
brew install graphicsmagick
brew install node
npm install gm
还是不行
