I get the error "Assertion failed (wrap->ssl_) != (nullptr), file src\tls_wrap.cc, line 320" trying to install any module by npm via proxy, for example, request or cheerio:

npm config set proxy http://username:password@proxy.company.com:8080
npm config set https-proxy https://username:password@proxy.company.com:8080

npm install cheerio

//

Thus, request module is not installed at all, and cheerio module is installed without dependencies.

//

npm --version
2.14.3

node --version
v4.1.0
