remove the compression plugin for webpack compression-webpack-plugin and install again

What impact it will be having on the functionality?

you need to remove the compression-webpack-plugin from prod as well. the impact is that the files won't be compressed

We solved it by installing Python x86 version between 2.5 and 3.0 on windows

FYI, for node-gyp related error, please make sure it met the requirements as mentioned in

https://github.com/nodejs/node-gyp

node-gyp on Windows is a nightmare :)
Most of the time, just running npm install --no-optional avoids the issue entirely as node-gyp is often requested through optional dependencies

I removed the compression-webpack-plugin to avoid errors in osx and windows

me helped: apt-get install build-essential
p.s. linux

I am getting the same errors in Windows. I tried several suggestions from above, but still no success

I see notes that you should "you need to remove the compression-webpack-plugin from prod as well. the impact is that the files won't be compressed"
How do you do this?

Could some one tell how to remove the compression-webpack-plugin?

Personal note to document this in the wiki for future Windows users.

I have latest version of Mac OS X together with latest version of Xcode and the same issue:

node-pre-gyp ERR! Tried to download(404): https://github.com/kelektiv/node.bcrypt.js/releases/download/v1.0.2/bcrypt_lib-v1.0.2-node-v46-darwin-x64.tar.gz

@michelgokan

I had the same issue @michelgokan but following @srinivasdamam post solved the issue for me. Hopefully it works for you

@dsebastien

@dsebastien thanks

try using LTS version of Nodejs instead of current version.

We had the same issue. To solve it, we upgraded the version of Node.

@srinivasdamam

@srinivasdamam solution worked for me

Same error:
node-pre-gyp ERR! Tried to download(404): https://node-inspector.s3.amazonaws.com/debug/v0.7.7/node-v51-linux-x64.tar.gz
node-pre-gyp ERR! Pre-built binaries not found for v8-debug@0.7.7 and node@7.3.0 (node-v51 ABI) (falling back to source compile with node-gyp)

I try and OK:
npm install -g node-inspector@0.7.5

Solution on macOS:
rm -rf /Users/LOGINNAME/.npm/
npm install -g PACKAGE

npm install --no-optional
it work for me

Works for me..

if you cannot solve with npm, use another package manager
brew install yarn
yarn add PACKAGE

@CaliforniaSoil

@CaliforniaSoil yarn didn't help either

@CaliforniaSoil

@CaliforniaSoil Even though I saw @ani-naslyan and his comment saying Yarn didn't work just as a last resort I tried it anyway.

Delete node_modules directory
using nvm for windows, I changed to version 6.11.4 of node
I installed the latest Yarn
I ran yarn in the root of my project
