在 node-gyp 构建期间找不到供应商文件答案

【问题标题】：Vendor File not found during node-gyp build在 node-gyp 构建期间找不到供应商文件

【问题描述】：

我愿意在heroku 上安装libvips 和sharp 的自定义版本。我使用运行没有错误的buildpacks，但是当涉及到node-gyp 编译时，它失败了here，说它无法访问/app/vendor/vips/lib/libvips-cpp.so。当我在不安装sharp的情况下运行构建然后连接heroku run bash，我可以看到文件在这个位置。

为什么 node-gyp 找不到呢？

我的构建包

=== my-site Buildpack URLs
1. heroku-community/apt
2. https://github.com/lechinoix/heroku-buildpack-vips
3. heroku/nodejs

非常感谢您的帮助！

【解决方案1】：

最后发现 heroku 正在一个目录/tmp/build_1f4c5c03 中创建整个/app 文件夹，该目录还包含新安装的供应商。在我的.pc 文件中，该包位于/app，因此无法找到。我使用heroku-prebuild npm 脚本来sed 放置路径：

TMP_DIR=$(pwd)

for file in $(grep -rl /app/vendor ${TMP_DIR}/vendor/vips/lib/pkgconfig)
do
  sed -i "s+/app/vendor+${TMP_DIR}/vendor+g" $file
done

不完全确定这是最好的方法......
