Question

我的操作系统是mac 10.9.2，ruby是2.0。

我已经使用brew install qrencode，但是当我运行gem install qrencoder时，它仍然有错误。

我列出了我的术语输出。

ZhouQi:git zhouqi$ gem install qrencoder
Building native extensions.  This could take a while...
ERROR:  Error installing qrencoder:

Answer 1

我使用此命令安装成功。

gem install qrencoder -- --with-qrencoder-include=/usr/local/Cellar/qrencode/3.4.2/include --with-qrencoder-lib=/usr/local/Cellar/qrencode/3.4.2/lib

我遇到了同样的错误，但确实如此：

MacBook-Pro: develop$ cd /
MacBook-Pro:/$ cd usr/local/Cellar/qrencode/3.4.3_1/
COPYING               INSTALL_RECEIPT.json  README                bin/                   lib/

MacBook-Pro:/$ cd usr/local/Cellar/qrencode/3.4.3_1/

MacBook-Pro:/$ z bitspark
MacBook-Pro:$ cd bitspark
MacBook-Pro:$ sudo gem install qrencoder -- --  with-qrencoder-include=/usr/local/Cellar/qrencode/3.4.3_1/include --with-qrencoder-lib=/usr/local/Cellar/qrencode/3.4.3_1/lib

在运行gem install qrencoder之前，您应该将qrencode版本替换为已安装的版本。

希望这有帮助！
