快遞3文件上傳：找不到模塊“可讀流”

Question

我正在按照本教程上傳文件。 我有一個帶有某些配置的Express 3服務器。 express.multipart給我一個Error: Cannot find module 'readable-stream'當我啟動所有內容時， Error: Cannot find module 'readable-stream'

服務器配置：

app.use(express.static(path.join(__dirname, 'public')));
app.use(express.logger('dev'));
app.use(express.methodOverride());
app.use(express.multipart({ uploadDir: __dirname + '/uploads', limit: '50mb' }))

路線：

app.post('/upload', function(req, res){
   console.log(req.files.file.name + ' has been uploaded')
   res.send(200)
})

html標記：

<form action='/upload' method='POST' enctype='multipart/form-data'>
    <input type='file' name='file'>
    <input type='submit' class='btn btn-default' value='Upload'>
</form>

我正在使用node v0.10.29和npm 1.4.14 。 處理文件上傳的最低Express配置是多少？ 還是我的環境有問題？

Answer 1

修復。

表達配置：

app.use(express.static(path.join(__dirname, 'public')));
app.use(express.logger('dev'));
app.use(express.methodOverride());
app.use(express.bodyParser({ uploadDir: path.join(__dirname + '/uploads'), keepExtensions: true }))

路線：

app.post('/upload', function(req, res){
    var fileName = req.files.fileName.name,
        filePath = req.files.fileName.path;

    console.log(fileName + ' added to uploads')

    // Do something with file here:
    // - save metadata to database
    // - upload file to S3 bucket

    // remove file from our server
    fs.unlink(filePath, function(err){
        console.log(fileName + ' has been deleted!')
    })
    res.redirect('/')
}
