When using node-gyp you might see an error like this when attempting to compile/install a node.js native addon:

$ npm install bcrypt

The main error here is:

Error: "pre" versions of node cannot be installed, use the --nodedir flag instead

This error is caused when you attempt to compile a native addon using a version of node.js with -pre at the end of the version number:

$ node -v
v0.10.4-pre

How to avoid (the short answer)

To avoid this error completely just use a stable release of node.js. i.e. v0.10.4, and not v0.10.4-pre.

How to fix (the long answer)

This error happens because node-gyp does not know what header files were used to compile your "pre" version of node, and therefore it needs you to specify the node source code directory path using the --nodedir flag.

For example, if I compiled my development ("pre") version of node.js using the source code in /Users/nrajlich/node, then I could invoke node-gyp like:

$ node-gyp rebuild --nodedir=/Users/nrajlich/node

Or install an native addon through npm like:

$ npm install bcrypt --nodedir=/Users/nrajlich/node

Always use --nodedir

Note: This is for advanced users who use -pre versions of node more often than tagged releases.

If you're invoking node-gyp through npm, then you can leverage npm's configuration system and not have to specify the --nodedir flag all the time:

$ npm config set nodedir /Users/nrajlich/node
