signed certificate in certificate chain & --cafile not working

so i have all the prerequisites from https://github.com/nodejs/node-gyp for a windows PC. I have latest version of node and npm and my .npmrc file is as such

registry=http://registry.npmjs.org/
NODE_TLS_REJECT_UNAUTHORIZED=0
strict-ssl=false
ca=
python=C:\Python27\python.exe
msvs_version=2015
maxsockets=20

the output is always the same, a self cert error . i've tried lots of different options. The issue is because i'm behind a company proxy that puts its own cert on so i can't get around the cert option using cafile option and they are not about to allow the cert to the exceptions. Ideally it be good if you could set the registry location same way you can for npm as then i could point it at an azure cloud VM that I use to host a private npm (using sinopia) that allow me to bypass the proxy. is there wa way to set the registry or even host a copy of it and use that instead?

i only want to compile sass buy as node-sass requires node-gyp seesm im stuck with trying to resolve this issue. We been able to work around it but using an older version of node and npm but should be able to use the latest version without all these issues

The ca property in your .npmrc is empty, it needs to point to a file containing your CA's public key in PEM format.

Hi,

thanks for replying :) , i tried changing the config to the below to use the cert that websesnse uses as a pem file, but i still get the same error :(

registry=http://registry.npmjs.org/
NODE_TLS_REJECT_UNAUTHORIZED=0
strict-ssl=false
ca=c:\test.pem
python=C:\Python27\python.exe
msvs_version=2015
maxsockets=20

but i still get

I'm not sure I understand. Your proxy connection is over unsecured HTTP so what do you need a custom CA for? If your proxy does MitM, the only way around that is by setting NODE_TLS_REJECT_UNAUTHORIZED=1 in the environment.

the proxy may be over http but nodejs.org/download is https. As the company proxy adds its own cert this causes the cert error (or so i believe). I didn't want to use the cert option but all google searches on this issue suggested setting the http and https proxy in .npmrc file (and even in your environmental variables); to the one your corporation uses is the only way to get npm to work over a proxy. I tried using just NODE_TLS_REJECT_UNAUTHORIZED=1 but still the same issue. Is there any way i can specify the repository that node-gyp uses so i could point it at a locally hosted copy of nodejs.org/download/ (this is how i got around hte issue with node/npm using local node repository though sinopia) im total blocked by the cert error. When i google this it seems its not an uncommon issue when working in a company behind a proxy, so you would hope there be more options available to work around the issue ;( Id do a pull request and compile my own version to achieve this if i wanted to learn how to write python (which i don’t) and if i wasn’t requiring this down from npm it self as part of the node-sass dependences

the proxy may be over http but nodejs.org/download is https. As the company proxy adds its own cert this causes the cert error (or so i believe).

That doesn't sound right. --cafile is for when your proxy or private registry serves a certificate that is signed by an internal CA. The certificate for nodejs.org is signed by a CA that's in the built-in root certificates list, you don't need extra certificates for that.

I think you may have to talk to your network administrators and have them help you troubleshoot this issue.

I tried using just NODE_TLS_REJECT_UNAUTHORIZED=1 but still the same issue.

How exactly did you set it? It completely disables certificate verification so it sounds unlikely that you still get the same error afterwards.

the proxy may be over http but nodejs.org/download is https. As the company proxy adds its own cert this causes the cert error (or so i believe).

Reading this again, do you mean your proxy does MitM? I.e., it decrypts the traffic, then re-encrypts it again using an internal cert/key before sending it on to you?

--cafile in theory works for that but such proxy servers seem to be misconfigured more often than not. You should check if you can connect through curl.

hi,

i set "NODE_TLS_REJECT_UNAUTHORIZED=1" within .npmrc and via the command line as an admin. I believe yes it dose decrypts the traffic, then re-encrypts it again using an internal cert/key before sending it on, i dont have to use the --cafile option but not using it seems to not work either. I was following http://stackoverflow.com/questions/13913941/how-to-fix-ssl-certificate-error-when-running-npm-on-windows but none of these seem to help

i use the curlt and that showed i can tunnel to the site , seems

Ah, you're using powershell. It has a builtin 'curl' alias and presumably it's picking up your global proxy settings but I was referring to the real curl, i.e., https://curl.haxx.se/. I'm curious if curl.exe --cacert yourca.pem https://nodejs.org/ works.

i couldn't get the curl.exe to work via command line

C:\Program Files\cURL\bin>curl.exe --cacert test.pem --capath c:\ https://nodejs
.org/
curl: (77) error setting certificate verify locations:
  CAfile: test.pem
  CApath: c:\
C:\Program Files\cURL\bin>curl.exe --capath c:\test.pem https://nodejs.org/
curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

so i thought i would use powershell to call install seeing as you said powershell is picking up the global proxy, and i got the following

so looked at fixing the "Error: %1 is not a valid Win32 application". which still comes from node-gyp comes from "Building: C:\Node\node.exe C:\node_modules\node-gyp\bin\node-gyp.js rebuild --verbose --libsass_ext= --libsass_cflags= --libsass_ldflags= --libsass_library="

i tried all the suggestions on slack , seem i may have to just power shell the .node-gyp files to the user folder manually as thats the only way it seems to work as cant compile node-gpy manually

I see two issues:

node-sass (not node-gyp) tries to download a precompiled binary from github that apparently doesn't match your architecture. Not a big deal because it falls back to building from source.
Executing C:\\Python27\python.exe fails. If you have a working python executable, pass it to node-gyp with --python <executable>.

yer python is defined in my system environmental variables and set in .npmrc but i tried passing it in the install call but still fails with self signed certificate in certificate chain, node-sass uses node-gyp to compile the scss files, i think unless there is an option to tell node-gyp to pull from a local repository or tell node-sass to use the c++ compiler instead (which i had hoped setting the ms version would have done, but seems to still try and use node-gyp first before falling back on the c++ compiler) ; or if .node-gyp complied files were part of the node-gpy module and came as part of it when you required it and could run from the module location instead of the users folder....in any case im stuck with having to powershell the .node-gpy folder from a VM to a local pc

you can see it find python and gets the version but still then falls over with the self signed certificate in certificate chain error

verb check python version
 `C:\\Python27\python.exe -c "import platform; print(platform.python_version());"` returned: "2.7.11\r\n"
gyp

ok i worked it out ,

my .npmrc file was uisng "ca=" but thats for when you want to set the cert file like so

ca="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"

but to use a cert file then you need to set cafile

cafile=/path/to/cert.pem

see https://docs.npmjs.com/misc/config#cafile

it seems setting cafile via node-gyp didn't work but having it set in .npmrc file dose. I suspect because im calling node-sass that node-gyp inherits the config !? any way...

registry=http://my-private-npm-repo/
strict-ssl=false
python=C:\Python27\python.exe
msvs_version=2015
NODE_TLS_REJECT_UNAUTHORIZED=0
proxy=http://websense-wcg.lan:8080
https-proxy=http://websense-wcg.lan:8080
cafile=C:\Forcepoint.pem

i still think its bad that node-gyp has hard coded paths to git and nodejs repository and that you cant configure it you use your own local repository. Been able to use a local repository instead of the one on the web allows developers in corporate environments behind firewalls and proxys a work around. So if you could allow a set registry option to it so one could use their own repository that would be really handy

thank you for all your help all the same 👍

i still think its bad that node-gyp has hard coded paths to git and nodejs repository and that you cant configure it you use your own local repository.

You can: --dist-url=<url>, or --nodedir <dir> if you have a local checkout.
