我正在尝试使用pip [参考：https://github.com/pipermerriam/eth-testrpc]通过MobaXterm终端在我的Windows机器上为以太坊安装TestRPC，如下所示：
pip install eth-testrpc
但是我收到以下错误： 使用缓存secp256k1-0.13.2.tar.gz 从命令python setup.py egg_info完成输出： 安装此软件包需要'pkg-config'。有关详细信息，请参阅自述文件。
无法解决。它说“pkg-config是必需的。它是否意味着包：pkgconfig。这个已安装：
[manindra.singh] ➤ pip install pkgconfig
Requirement already satisfied (use --upgrade to upgrade): pkgconfig in /usr/lib/python2.7/site-packages
完整的命令执行：
[manindra.singh] ➤ pip install eth-testrpc
