无效的数字参数'/Wsign-compare'：无法在Windows上安装pip包或构建相应的库

Question

我已经在 Linux 上使用 python 模块

apriltag

（在此处 https://pypi.org/project/apriltag/）有一段时间了，需要将我的系统转移到 Windows。在我的 Windows 机器上，我尝试在 python3.6 上安装 apriltag pip 包：

python -m pip install apriltag

但是轮子无法建造，给了我一个很长的错误列表，我相信其中的关键行是

构建自定义规则 C:/Users/xxxx/apriltag_3b8f424df9f543459d5bd3db09137d9f/core/CMakeLists.txt cl : 命令行错误 D8021: 无效的数字参数 '/Wsign-compare'```

担心 PyPI 包可能无法在 Windows 上运行（？）我查看了它所基于的项目，在此处找到 https://github.com/swatbotics/apriltag。克隆到它并使用 Visual Studio 构建它，第一个构建失败并显示

错误 D8021 无效的数字参数 '/Wsign-compare'

我在这里查看了

/Wsign-compare

，但没有发现任何人遇到该错误的例子，更不用说解决它了。让我知道是否有解决办法，或者这个存储库是否永远不会在 Windows 上构建。

谢谢:)

编辑：添加了上下文的整个Python构建日志

python -m pip install apriltag

Answer 1

我在 PyPI

apriltag

库中遇到了同样的错误。

简短回答：不要使用这个维护不善的库。请改用

pupil-apriltags

，这也适用于 Windows。

更多详情

我们正在尝试通过
```
apriltag
```
安装的 PyPI 包
```
pip install apriltag
```
[https://pypi.org/project/apriltag/#description] 显然是一个名为 Bernd Winkler 的人的“非官方包”，最后更新于 2018 年 12 月 7 日。
由 Matt Zucker 创建的实际 Python 包装器模块 [https://github.com/mzucker] 最后更新于 GitHub 2018 年 7 月 18 日在https://github.com/swatbotics/apriltag。
仅供参考，Matt 的包装器是由密歇根大学 April Lab 编写的 C 代码，该实验室的负责人为 Edwin Olson，他于 2010 年 5 月发明了 AprilTags。[https://github.com/AprilRobotics/apriltag]。

马特说：

“请注意：我不是 https://pypi.org/project/apriltag/ 中列出的 pypi 包的维护者 – 此处提交的报告该包问题的 GitHub 问题将被立即关闭。抱歉，我不'没时间支持别人的非官方包。”

因此，更好的安装过程将从 Matt 在他的 GitHub 存储库中所说的开始：

cd /path/to/apriltag
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j4
如果您想将库和重要的二进制文件安装到系统目录中，则可以输入
sudo make install

注意：

apriltag

似乎不适用于 Windows：

对我来说，在 Windows 上，“make”命令不可用，所以我遵循了this：

在 https://chocolatey.org/install
奔跑
```
choco install make
```

即便如此，make 命令也没有执行任何操作。

但是，在 Windows 上运行后：

import cv2
import apriltag

img = cv2.imread('test.jpg', cv2.IMREAD_GRAYSCALE)
detector = apriltag.Detector()
result = detector.detect(img)

print(result)

给出错误：

AttributeError: module 'os' has no attribute 'uname'

，该错误仅在 UNIX 上可用。

在搜索中，我发现了其他维护得更好的用于 AprilTag C 绑定的 Python 库。特别是这个：瞳孔_apriltags。它可以在 Windows 上运行。
