How to fix fs re-evaluating native module sources is not supported - graceful-fs

Question

Recently I ve made a switch to Node v 6  and It started creating more and more problems with running normal builds grunt gulp webpack  For example     gulp  14 02 20  Local gulp not found in    Other angular-2-ts angular2-seed  14 02 20  Try running  npm install gulp   while gulp and all other plugins and modules are installed  and even re-installed via rm -rf node modules  in  node modules folder   Most of those errors have line like   node 42  fs  re-evaluating native module sources is not supported   If you are using the graceful-fs module   please update it to a more recent version    with 42 as arbitrary number  Like in that issue I ve submitted - in angular2-seed repo https   github com mgechev angular2-seed issues 902  What I ve tried to do is downgrade to Node v 5 via n  https   www npmjs com package n  - it worked  Then remove all node modules folders  then do   npm info graceful-fs -v 3 3 6   ok  lets upgrade or remove and install new   npm i graceful-fs latest npm i graceful-fs 4 1 4 sudo npm i graceful-fs 4 1 4 -g   all results in   npm info graceful-fs -v 3 3 6   So now I am currenlty stuck with graceful-fs 3 3 6 or even worse in some modules dependances  like    angular2-seed   npm install    other lines   npm WARN deprecated graceful-fs 1 2 3  graceful-fs v3 0 0 and before  will fail on node releases  gt   v7 0  Please update to graceful-fs  4 0 0  as soon as possible  Use  npm ls graceful-fs  to find it in the tree    What could be the strategy here    Manually patch all the deps that contain graceful-fs  lt  4 0 0  There s some global switch to use specific package version  Reinstall everything

The report says   a file is missing in     vendor win32-x64-48 binding node  I looked for the binding node file and I find it in     https   github com sass node-sass-binaries  Copy the correct file with the name binding node and it works

Type npm list graceful-fs and you will see which versions of graceful-fs are currently installed   In my case I got   npm list graceful-fs   request promise-core 0 0 1  projects request promise-core  -- gulp 3 9 1    -- vinyl-fs 0 3 14      -- glob-watcher 0 0 6        -- gaze 0 5 2          -- globule 0 1 0            -- glob 3 1 21              -- graceful-fs 1 2 3         lt               -- graceful-fs 3 0 8   -- publish-please 2 1 3    -- nsp 2 4 0      -- nodesecurity-npm-utils 4 0 1        -- silent-npm-registry-client 2 0 0          -- npm-registry-client 7 1 0            -- graceful-fs 4 1 3     -- read-pkg 1 1 0      -- load-json-file 1 1 0        -- graceful-fs 4 1 4   As you can see gulp deep down depends on a very old version  Unfortunately  I can t update that myself using npm update graceful-fs  gulp would need to update their dependencies  So if you have a case like this you are out of luck  But you may open an issue for the project with the old dependency - i e  gulp

As described here  you can also attempt the command  npm cache clean   That fixed it for me  after the other steps had not fully yielded results  other than updating everything

Or try to update node   brew upgrade node   If it is installed with brew  like in my case   sudo npm update -g npm did not solve the  same  problem for me

Just to point out that cordova brings in it s own npm with the graceful-fs dependency  so if you use Cordova make sure that it is the latest so you get the latest graceful-fs from that as well
