我正在尝试zbar在我的Windows x64机器上安装:

任何人都知道如何解决这个问题？

Answer 1

您正在尝试安装zbar包pip.执行此操作时,请pip下载源并尝试编译此项目的C/C++源代码.

要做这样的事情,你需要一个C/C++编译器并拥有所有依赖项.pip编译这个包可能很复杂.

另一种解决方案是下载嵌入所有二进制文件的二进制轮.zbar开发人员建议从他们的GitHub网页下载二进制轮

您可以下载这个二进制轮,它针对Windows Python 2.7 64位安装.

你所要做的就是:

• 用Windows+R里面的内部运行打开Windows clicmd
• 转到您已下载whl文件的目录,并附带cd说明
• 跑 pip install zbar-0.10-cp27-none-win_amd64.whl

例如,命令可以是

pip install zbar-0.10-cp27-none-win_amd64.whl

如果您有多个Python安装,请确保使用正确的pip程序.

您可以为任何包含一些必须编译的代码的包执行此操作
