错误:"pre"无法安装版本的节点，请改用--nodedir标志 [英] Error: "pre" versions of node cannot be installed, use the --nodedir flag instead

问题描述

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:

I'm trying to install opencv for node. I don't think this has anything to do with opencv directly, rather it has to do with node-gyp. I had success in installing opencv on my mac but when I try to do the exact same on Ubuntu server I get the following error after doing 'npm install opnecv':

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

我还尝试下载源代码并执行"node-gyp rebuild"，结果类似:

I also tried downloading the source code and doing 'node-gyp rebuild' with similar results:

以前有人遇到过这个问题吗?

Has anyone had this issue before?

推荐答案

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

Use npm install --nodedir=/path/to/node opencv, where /path/to/node is a path to current nodejs source code.

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

It happens because node-gyp can't find source to your custom build, and here is the discussion about it: 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.

You can commonly fix this by creating a symbolic link if you have super user permissions.

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

然后再次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，因为其他软件可能会依赖它.

Then npm install again, and it will likely find it. Don't do this if /usr/lib/node already exists, as other software may depend on it.
