Question

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opencv但是当我尝试在Ubuntu服务器上做同样的事情时，我在做'npm install opnecv'后得到以下错误：

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

我也尝试下载源代码并执行'node-gyp rebuild'，结果类似：

demo@camera:~/src/node$ node-gyp rebuild

以前是否有人遇到此问题？

Answer 1

我还能够通过以下方式将我的节点版本升级到稳定版本（例如，不是“前”版本 - 您的版本为0.8.13-pre）来解决此问题：

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

Answer 2

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

之所以发生这种情况是因为node-gyp找不到自定义构建的源代码，以下是对它的讨论：https://github.com/TooTallNate/node-gyp/issues/86

如果您拥有超级用户权限，则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

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

错误：无法安装节点的“预”版本，请改用--nodedir标志
