TypeError: Request path contains unescaped characters

[Tobbe]

This is the output I get when I try to install a package that needs node-gyp (node-sass in this case):

The error message at the core of it all seems to be "TypeError: Request path contains unescaped characters". Which is very confusing, because google seems to suggest it's something wrong with my proxy settings. But I don't know what it could be.

Some relevant information about my system setup:

$ npm config list | grep 'proxy\|ssl\|registry'
https-proxy = "http://proxy.company.com:8080/"
proxy = "http://proxy.company.com:8080/"
registry = "http://nexus.company.com/nexus/path/to/npm-modules/"
strict-ssl = false

$ git config --list | grep 'proxy\|sslverify'
http.proxy=http://proxy.company.com:8080
http.sslverify=false

$ env | grep -i 'node_tls\|proxy'
NODE_TLS_REJECT_UNAUTHORIZED=0
HTTP_PROXY=http://proxy.company.com:8080

What is wrong/missing in my setup?

You can sort of figure most of it out from the error message above, but just to be clear: This is on Windows 7 with node v5.9. I've also tried 5.12, 6.4 and 6.5

[Tobbe]

I can manually download the header files and specify the path to them with --tarball, but then I get stuck on issue #1002 And even if that would have worked it wouldn't have been a good solution in the long run :)

[bnoordhuis]

That 'Request path contains unescaped characters' means there is a space in the request path (because that's all node.js core checks for.)

I don't know exactly what goes wrong but apparently something somewhere is letting a blank slip through.

[Tobbe]

Any idea how to debug this further?

[bnoordhuis]

Not really. Maybe add a few console.log statements to tunnel-agent/index.js? env NODE_DEBUG="http tunnel" node-gyp <cmd> (adjust for windows shell syntax) might help too.

[Tobbe]

If I manually run npm install node-sass before npm install everything works. I will investigate further.
