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。我在Mac上成功安装了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 gyp ERR! configure error gyp ERR! stack Error: "pre" versions of node cannot be installed, use the --nodedir flag instead gyp ERR! stack at install (/usr/local/lib/node_modules/node-gyp/lib/install.js:69:16) gyp ERR! stack at Object.commands.forEach.self.commands.(anonymous function) [as install] (/usr/local/lib/node_modules/node-gyp/lib/node-gyp.js:56:37) gyp ERR! stack at getNodeDir (/usr/local/lib/node_modules/node-gyp/lib/configure.js:181:20) gyp ERR! stack at /usr/local/lib/node_modules/node-gyp/lib/configure.js:101:9 gyp ERR! stack at ChildProcess.exithandler (child_process.js:538:7) gyp ERR! stack at ChildProcess.EventEmitter.emit (events.js:96:17) gyp ERR! stack at maybeClose (child_process.js:638:16) gyp ERR! stack at Process._handle.onexit (child_process.js:680:5) gyp ERR!

我还尝试下载源代码并执行“ node-gyp rebuild”,结果类似:
demo@camera:~/src/node$ node-gyp rebuild gyp info it worked if it ends with ok gyp info using node-gyp@0.7.1 gyp info using node@0.8.13-pre | linux | x64 gyp ERR! configure error gyp ERR! stack Error: "pre" versions of node cannot be installed, use the --nodedir flag instead gyp ERR! stack at install (/usr/local/lib/node_modules/node-gyp/lib/install.js:69:16) gyp ERR! stack at Object.commands.forEach.self.commands.(anonymous function) [as install] (/usr/local/lib/node_modules/node-gyp/lib/node-gyp.js:56:37) gyp ERR! stack at getNodeDir (/usr/local/lib/node_modules/node-gyp/lib/configure.js:181:20) gyp ERR! stack at /usr/local/lib/node_modules/node-gyp/lib/configure.js:101:9 gyp ERR! stack at ChildProcess.exithandler (child_process.js:538:7) gyp ERR! stack at ChildProcess.EventEmitter.emit (events.js:96:17) gyp ERR! stack at maybeClose (child_process.js:638:16) gyp ERR! stack at Process._handle.onexit (child_process.js:680:5) gyp ERR!

有人遇到过这个问题吗?
使用npm install --nodedir=/path/to/node opencv,其中/path/to/node是当前nodejs源代码的路径。
npm install --nodedir=/path/to/node opencv
/path/to/node
发生这种情况是因为node- gyp找不到您的自定义版本的源,下面是有关它的讨论: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
然后npm install,它很可能会找到它。如果/ usr / lib / node已经存在,请不要执行此操作,因为其他软件可能依赖于此。
npm install
