Question

我在尝试排除文件（like so in Browserify）时遇到问题。

使用此命令：

int Student::readRecord(fstream & in, Student s[])

{

int j = 0;

if (!in)

{
    cout << "cannot open the file or file does not exists\n";
    exit(0);
}

else

{
    char name[30];
    int g[5];
    char ch;
    while (in)

    {
        in >> name;
        for (int i = 0; i<5; i++)
        {
            in >> g[i];
            if (i != 4)
                in >> ch; 
        }

        s[j].setName(name);
        s[j].setGrade(g);
        j++;

    }
}

return j - 1;

}

它首先编译好，但在对观察文件进行任何更新时会出错。这是完整的输出：

watchify scripts/main.js -o scripts/main.bundle.js -t strictify -v -x scripts/libs.js

这是任何变通办法的已知问题吗？现在，我可以编辑1036 bytes written to scripts/main.bundle.js (0.04 seconds) fs.js:430 binding.open(pathModule._makeLong(path), ^ TypeError: path must be a string at Object.fs.open (fs.js:430:11) at OpenReq.process (/usr/lib/node_modules/watchify/node_modules/chokidar/node_modules/readdirp/node_modules/graceful-fs/graceful-fs.js:55:16) at OpenReq.Req (/usr/lib/node_modules/watchify/node_modules/chokidar/node_modules/readdirp/node_modules/graceful-fs/graceful-fs.js:126:8) at new OpenReq (/usr/lib/node_modules/watchify/node_modules/chokidar/node_modules/readdirp/node_modules/graceful-fs/graceful-fs.js:49:7) at Object.open (/usr/lib/node_modules/watchify/node_modules/chokidar/node_modules/readdirp/node_modules/graceful-fs/graceful-fs.js:41:3) at ReadStream.open (fs.js:1509:6) at new ReadStream (fs.js:1496:10) at Object.fs.createReadStream (fs.js:1450:10) at Deps.readFile (/usr/lib/node_modules/watchify/node_modules/browserify/node_modules/module-deps/index.js:190:17) at /usr/lib/node_modules/watchify/node_modules/browserify/node_modules/module-deps/index.js:365:14并为生产做一个常规的Browserify构建（以排除文件），但是对于开发来说，这会使Watchify任务稍微变慢。

感谢您的帮助！

一种解决方法是完全跳过Watchify并使用nodemon来处理观看。这是用于开发和生产构建的完整package.json：

{
    "private": true,
    "devDependencies": {
        "node-sass": "latest",
        "autoprefixer": "latest",
        "browserify": "latest",
        "strictify": "latest",
        "uglify-js": "latest",
        "nodemon": "latest"
    },
    "scripts": {
        "build:main:bundle": "browserify scripts/main.js -o scripts/main.bundle.js -x ./scripts/libs.js -t strictify",
        "build:main:uglify": "uglifyjs scripts/main.bundle.js -c -o scripts/main.bundle.js",
        "build:main": "npm run build:main:bundle && npm run build:main:uglify",
        "build:libs:bundle": "browserify -r ./scripts/libs.js -o scripts/libs.bundle.js -t strictify",
        "build:libs:uglify": "uglifyjs scripts/libs.bundle.js -c -o scripts/libs.bundle.js",
        "build:libs": "npm run build:libs:bundle && npm run build:libs:uglify",
        "build:styles": "node-sass --stdout --output-style compressed styles/styles.scss | autoprefixer -o styles/styles.css",
        "build": "npm run build:main && npm run build:libs && npm run build:styles",
        "watch:main": "nodemon -e js -w scripts -i scripts/main.bundle.js -x 'npm run build:main:bundle'",
        "watch:styles": "nodemon -e scss -w styles -x 'npm run build:styles'",
        "watch": "npm run watch:main & npm run watch:styles"
    }
}

这允许使用这两个命令进行开发（使用watch）和生产（使用build）：

npm run watch
npm run build

唯一需要注意的是做手册

npm run build:libs

无论何时更新scripts / libs.js文件（其中包含jQuery / Backbone / TweenLite等文件，因此您不必经常更新）。有关完整示例，请参阅：Weblate。
