错误：无法安装节点的“pre”版本，请改用–nodedir标志
我正在尝试为节点安装opencv 。 我不认为这与opencv直接有什么关系，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服务器上完全相同时，在执行'npm install opnecv'后出现以下错误：

有没有人有过这个问题？
使用npm install --nodedir=/path/to/node opencv ，其中/path/to/node是当前nodejs源代码的path。
发生这种情况是因为node-gyp无法find自定义构build的源代码，下面是关于它的讨论： 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build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再次npm install ，它可能会find它。 如果/ usr / lib /节点已经存在，不要这样做，因为其他软件可能依赖它。
我也可以通过将我的节点版本升级到一个稳定的版本（例如不是“pre”版本 – 你的版本是0.8.13-pre ）来解决这个问题。
sudo npm install -gn # install node version manager "n" sudo n stable # install the latest stable version of node
