The conditions for this problem occur are:

Install NPM on Linux in the Bitcore official form, with an error:

The various NPM sources have since been replaced and cannot be resolved. We all know the Chinese wall is very high, so fq, but the method of VPN with Linux is more complicated, so I installed the ccproxy on my own VPN computer, as a Linux agent, then set up NPM proxy under Linux:

NPM Config set proxy http://server:portnpm config set https-proxy http://server:port after Setup can be used: NPM config ls to view the NPM source and proxy set is not what you want. After setting up, you can see the connection information in Ccproxy, but still can't download it. Further discovery was the fault in the downloading bitcoin:https://github.com/bitpay/bitcoin/releases/download/v0.12.1-bitcore-4/, This download is generally used in the way of curl, so setting up the NPM agent does not solve the problem of curl. Then I set the global proxy, at the end of the ~.BASHRC add the following command: Export http_proxy=http://server:port "Export https_proxy=" Http://server:port " export ftp_proxy= "Http://server:port"Then run the source ~/.BASHRC let the configuration take effect, it should be OK, but the result is still no. What's the problem? Because I run the source ~/.BASHRC command is wrong, it is said that this command is only valid for the current seesion, so you have to install the Bitcore interface to use, it turns out that this is really the problem. However, there is a problem: when I installed the Bitcore, and then installed the BWS and insight, the results found that BWS and insight between the communication between the wrong, but the BWS and insight alone to test, can be. Later found to be a proxy problem, because I set the proxy before, so the data are sent to my other computer. So after using the proxy, remember to reset: unset http_proxyAnd the other two, the blood and tears of the lesson AH.
