Windows10 在安装sqlite3@3.1.3时，一直卡在这里

node-pre-gyp install --fallback-to-build

半天半天不动，上网找了很久也没有解决。中间以为是官方库太慢，换了个仓库地址也没用。于是就开始自己折腾了，先是在Github上找到了node-pre-gyp这个项目看了一下README.md，https://github.com/mapbox/node-pre-gyp，看了一下帮助：

install - Install pre-built binary for module
...
--fallback-to-build: fallback to building from source if pre-built binary is not available

于是就知道了 node-pre-gyp install --fallback-to-build是用来先检测是不是已经安装好了二进制库，没有的话就安装。

然后又打开node_modules/sqlite3/看了看sqlite3的package.json，找到了这行语句的所在：

"scripts": {
    "prepublish": "npm ls",
    "install": "node-pre-gyp install --fallback-to-build",
    "pretest": "node test/support/createdb.js",
    "test": "mocha -R spec --timeout 480000"
  },

接着就在这个目录下打开一个控制台，直接运行node-pre-gyp install --fallback-to-build，出现下面的信息：

node-pre-gyp info it worked if it ends with ok
node-pre-gyp info using node-pre-gyp@0.6.32
node-pre-gyp info using node@4.4.4 | win32 | x64
node-pre-gyp info check checked for "E:\MyProjects\MyGhost\node_modules\sqlite3\lib\binding\node-v46-win32-x64\node_sqlite3.node" (not found)
node-pre-gyp http GET https://mapbox-node-binary.s3.amazonaws.com/sqlite3/v3.1.3/node-v46-win32-x64.tar.gz

然后半天半天不动。。。于是就明白问题出在哪了。。。竟然就是因为**被！墙！了！**因为不关镜像地址的事，所以换个国内的镜像没用。

开了个VPN，再次运行node-pre-gyp install --fallback-to-build，出现了下面的内容：

node-pre-gyp info it worked if it ends with ok
node-pre-gyp info using node-pre-gyp@0.6.32
node-pre-gyp info using node@4.4.4 | win32 | x64

[sqlite3] Success: "E:\MyProjects\MyGhost\node_modules\sqlite3\lib\binding\node-v46-win32-x64\node_sqlite3.node" is installed via remote
node-pre-gyp info ok

这样就安装成功了。
