使用Grunt替换文件中的文本 [英] Using Grunt to Replace Text in a File

问题描述

我正在尝试让Grunt替换路径引用，但是我不确定自己做错了什么.这看起来应该可以工作.本质上，我是将Bootstrap文件复制到目录中并更改@import路径，因此我只是尝试用新的目标路径"MY/NEW/DEST/PATH/bootstrap"替换"bootstrap/".我不想像这样直接使用模块，这似乎是不必要的.除了替换之外，一切都正常.

I'm trying to get Grunt to replace a path reference and I'm not sure what I'm doing wrong. This looks like it should work. Essentially, I'm copying a Bootstrap file up a directory and changing the @import paths, so I'm just trying to replace 'bootstrap/' with the new destination path 'MY/NEW/DEST/PATH/bootstrap'. I don't want to use a module for something as straight forward as this, seems needless. Everything works but the replace.

var destFilePath = path.join(basePath, file);

// Does the file already exist?
if (!grunt.file.exists(destFilePath)) {

    // Copy Bootstrap source @import file to destination
    grunt.file.copy(

        // Node API join to keep this cross-platform
        path.join(basePath, 'bootstrap/_bootstrap.scss'),
        destFilePath
    );

    // Require node filesystem module, since not a global
    var fs = require('fs');

    // Replace @import paths to be relative to new destination                                
    fs.readFile(destFilePath, 'utf8', function(err, data) {

        // Check for any errs during read
        if (err) {
            return grunt.log.write(err);
        }

        var result = data.replace('/bootstrap\//g', 'bootstrap/bootstrap/');

        fs.writeFile(destFilePath, result, 'utf8', function(err) {
            return grunt.log.write(err);
        });
    });
}

推荐答案

您将正则表达式用引号引起来-不要这样做，它应该可以正常工作:

You wrapped your regex in quotes - don't do that and it should work fine:

var result = data.replace(/bootstrap\//g, 'bootstrap/bootstrap/');
