I successfully installed version 4.0.1

1. npm install secp256k1
2. npm install bitcoinjs-lib

but ,there are anthor question , current of version ,it not dependent on bigi , Does the api change anything?

[dcousens]

@fanatid how did installing secp256k1 resolve his issue?
@silence-may are you confident that they were the commands you used?

but ,there are anthor question , current of version ,it not dependent on bigi , Does the api change anything?

Yes, the API has changed completely.
Please read the CHANGELOG.

We use Buffer objects instead of bigi instances for cross compatibility.

[fanatid]

@silence-may did you installed something between first attempt of installing bitcoinjs-lib and installing secp256k1? like windows-build-tools?

[boris-kolar]

The build fails on my machine too. It fails when compiling native module. The steps required to make installation succeed are a bit advanced for (it involves installing build tools and python 2.7). Another workaround is installing with "--ignore-scripts" npm option. @dcousens: can you make building native dependencies optional, so the package will install on all systems? Native modules shouldn't be required for those looking to use the library in the browser.

[silence-may]

@fanatid I only installed these two plugins.

[silence-may]

@boris-kolar, with "--ignore-scripts" npm option can success? Is the method I installed wrong? But I also installed it successfully.

[boris-kolar]

@silence-may yes, with --ignore-scripts it installs (this works for me: npm i --ignore-scripts bitcoinjs-lib).

[prahaladbelavadi]

node-gyp rebuild failed while installing secp256k1 and other crypto dependant libraries because it required python 2.7 as @boris-kolar mentioned.
I ended up creating a virtualenv using anaconda with python 2.7 and installing secp256k1 after.

[dcousens]

I don't think this is a problem so much as a requirement that maybe could be better documented?

Python 2.7 is required to build the native code at this time.

[boris-kolar]

The problem is: bitcoinjs-lib installation fails if npm can't build native code, which is not required for all projects. A warning instead of failure would be more appropriate (see https://docs.npmjs.com/all#best-practices). Workarounds like --ignore-scripts are cumbersome when bitcoinjs-lib is just a dependency). What about somthing like:

node-gyp rebuild || node -e 'console.log("WARNING: failed to build native code")'

[dcousens]

@boris-kolar understandable, but I think in this case explicit is better than the implicit 'opt-in' nature of a warning...
