我正在尝试为节点安装opencv。我认为这与opencv没有直接关系，而是与node-gyp有关。我成功地在我的 Mac 上安装了 opencv，但是当我尝试在 Ubuntu 服务器上执行完全相同的操作时，在执行“npm install opnecv”后出现以下错误：

npm http GET https://registry.npmjs.org/opencv
npm http 304 https://registry.npmjs.org/opencv

> opencv@0.0.7 preinstall /home/demo/node_modules/opencv
> node-gyp rebuild

我还尝试下载源代码并执行“node-gyp rebuild”，结果相似：

demo@camera:~/src/node$ node-gyp rebuild
gyp info it worked if it ends with ok

以前有人遇到过这个问题吗？

我还可以通过将我的节点版本升级到稳定版本（例如，不是“预”版本 - 你的版本是0.8.13-pre）来解决这个问题：

sudo npm install -g n # install node version manager "n"
sudo n stable # install the latest stable version of node

使用npm install --nodedir=/path/to/node opencv, where/path/to/node是当前 nodejs 源代码的路径。

发生这种情况是因为 node-gyp 无法找到您的自定义构建的源代码，这里是关于它的讨论：https ://github.com/TooTallNate/node-gyp/issues/86

如果您具有超级用户权限，通常可以通过创建符号链接来解决此问题。

chmod a+r /path/to/node -R
cd /usr/lib
sudo ln -s /path/to/node node

再说npm install一遍，它很可能会找到它。如果 /usr/lib/node 已经存在，不要这样做，因为其他软件可能依赖它。
