- 为安装poppler gem包，使用PDF渲染库，但是遇到以下错误：
Building native extensions. This could take a while... ERROR: Error installing poppler: ERROR: Failed to build gem native extension.
- 查询提示信息原来是，无法调用brew install poppler，单独运行此命令又出现如下错误：

- 按照提示提示，运行brew install python，同样遇到make错误。
- 经过两天不断思考，google结果未果情况下，尝试将brew下载的包进行手动编译：
# 将安装包解压 cd /Library/Caches/Homebrew/Python-2.7.8 # 需要和brew安装是运行命令一直，可在上面的信息中得到 ./configure --prefix=/usr/local/Cellar/python/2.7.8_2 --enable-ipv6 --datarootdir=/usr/local/Cellar/python/2 make install # 运行doctor可查看到手动编译会造成未链接警告 brew doctor # 链接所有python路径 brew link python # 又提示，某些文件没有权限，直接按照提示使用强制写入 brew link --overwrite --dry-run python # 现在python以安装完好，运行一下命令可以查看到 brew list # 现在开始重新安装poppler brew install poppler gem install poppler
