I am using ubuntu16.04 created by virtual box in win7 system, and I encountered the following error when using npm install bcrypt to install the bcrypt plug-in:

I used the ubuntu system directly before, using the same method, and the above error did not occur. Please help me solve it. Thank you very much! !

Answer 1

The main message of the error message is that the package you installed depends on a native module built with c++/c. This module needs to download the release file compiled for linux and build it through node-gyp. However, the pull failed due to network problems, so an error was reported.

One way is to check your network configuration, such as curl or wget to confirm that the network in the virtual machine terminal can pull this dependency.

Another way is to set up the domestic image source npm warehouse and reinstall it:

npm set registry https://registry.npm.taobao.org
npm install
