从 pip 安装时找不到文件

我一直在尝试解决在 Lubuntu 17.04 中安装 python 包时发现的一个问题。

该软件包适用于 python 3.5 64 位。它被称为 RawPy，依赖于 LibRaw 库。我已经安装了 LibRaw 库，但在尝试安装 RawPy 时，无法找到 LibRaw 安装的一些文件：

我已检查，发现 usr/local/lib/libraw 中存在缺失文件。尝试使用 ldconfig 添加该路由，但没有成功。

LibRaw 似乎已安装。当我写入时ldconfig -p，我得到：

libraw1394.so.11 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libraw1394.so.11
libraw_r.so.16 (libc6,x86-64) => /usr/local/lib/libraw_r.so.16
libraw_r.so.16 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libraw_r.so.16
libraw_r.so (libc6,x86-64) => /usr/local/lib/libraw_r.so
libraw.so.16 (libc6,x86-64) => /usr/local/lib/libraw.so.16
libraw.so.16 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libraw.so.16
libraw.so (libc6,x86-64) => /usr/local/lib/libraw.so

确实如此：

lubuntu@lubuntu:~$ sudo apt install libraw-dev

lubuntu@lubuntu:~$

该文件的位置如下：

lubuntu@lubuntu:~$ sudo find / -name libraw_version.h
/usr/include/libraw/libraw_version.h
/usr/local/include/libraw/libraw_version.h
/home/lubuntu/libraw/libraw/libraw_version.h
find: ‘/run/user/999/gvfs’: Permission denied
lubuntu@lubuntu:~$

第三个位置是来自 GitHub 的源代码下载文件夹。我也编译了最后一个版本的代码，但没有成功

有没有办法明确告诉 pip 在特定路径中查找依赖项？我甚至想过更改源代码以明确说明路径，但我不认为这是正确的解决方法。

有人有什么想法吗？

答案1

免责声明：我是 rawpy 的开发者。

我不确定您遇到的具体问题，但我最近发布了一个新版本，它为 Linux（除了 Windows 和 macOS）提供了二进制包（wheels），因此不再需要编译或手动安装 libraw。只需重新安装 rawpy，它就可以立即使用。

答案2

尝试 echo "/usr/local/lib" | sudo tee /etc/ld.so.conf.d/99local.conf

其次是sudo ldconfig。

这是从 rawpy 的安装说明。
