Javascript 未能加载c++；bson扩展，使用monk访问Mongodb时使用纯JS版本

当我想使用monk作为访问mongodb的中间件时，它会提示

无法加载C++ BSON扩展，使用纯JS版本 我的运行evn如下所示：

约塞米蒂

节点v0.10.32

npm 1.4.28

Mongodb 2.6.5

蒙克0.9.1 你们有谁知道如何解决这个问题吗

答案是肯定的

转到monk index.js文件（

yourProjectDirectory/node\u modules/monk/node\u modules/mongodb/node\u modules/bson/ext/index.js

）

应该是这样的

try {
    // Load the precompiled win32 binary
    if(process.platform == "win32" && process.arch == "x64") {
      bson = require('./win32/x64/bson');  
    } else if(process.platform == "win32" && process.arch == "ia32") {
      bson = require('./win32/ia32/bson');  
    } else {
      bson = require('../build/Release/bson');  
    }   
} catch(err) {
    // Attempt to load the release bson version
    try {
        bson = require('../build/Release/bson');
    } catch (err) {
        console.dir(err)
        console.error("js-bson: Failed to load c++ bson extension, using pure JS version");
        bson = require('../lib/bson/bson');
    }
}

将挡块更改为

try {
...
} catch(err) {
    // Attempt to load the release bson version
    try {
        bson = require('../browser_build/bson');
    } catch (err) {
        console.dir(err)
        console.error("js-bson: Failed to load c++ bson extension, using pure JS version");
        bson = require('../lib/bson/bson');
    }
}

希望这有帮助

是不是有些东西实际上不起作用了，或者您只是担心这条消息？可能是因为安装时make工具不可用。请尝试查看中的解决方案，这是不是有些东西实际上不起作用，或者您只是担心这条消息？可能是因为安装时make工具不可用。请尝试查看中的解决方案，这是不是有些东西实际上不起作用，或者您只是担心这条消息？可能是因为安装时make工具不可用。请尝试查看中的解决方案，这是不是有些东西实际上不起作用，或者您只是担心这条消息？可能是因为安装时make工具不可用。试着看一下中的解决方案
