FS.Transform.createWriteStream變換函數失敗，錯誤

我想上傳使用流星CollectionFSFS.Transform.createWriteStream變換函數失敗，錯誤

Simlpe圖片上傳已成功上傳的圖片。

但現在我儘量保留圖像的縮略圖。

，但它給了以下錯誤：

W20151211-14:38:38.240(5)? (STDERR) FS.Transform.createWriteStream transform function failed, Error:

這裏是我的代碼：

var createThumb = function(fileObj, readStream, writeStream) { 
    // Transform the image into a 10x10px thumbnail 
    gm(readStream, fileObj.name()).resize('10', '10').stream().pipe(writeStream); 
}; 

Images = new FS.Collection("images", { 
    stores: [ 
    new FS.Store.FileSystem("thumbs", { transformWrite: createThumb }, {path: "~/uploads/thumbs"}), 
    new FS.Store.FileSystem("images", {path: "~/uploads"}), 
    ], 
    filter: { 
    allow: { 
     contentTypes: ['image/*'] //allow only images in this FS.Collection 
    } 
    } 
});

我還增加了以下packege：

meteor add cfs:graphicsmagick

那麼究竟是什麼我在這裏失蹤？

安裝圖形magick。該軟件包只是gm的包裝，您必須安裝它。

我不記得確切的界面，但我認爲Fs的收集只接受一個對象，以便改變：

new FS.Store.FileSystem("thumbs", { transformWrite: createThumb }, {path: "~/uploads/thumbs"})

在：

new FS.Store.FileSystem("thumbs", { transformWrite: createThumb , path: "~/uploads/thumbs"})

我並安裝它。現在沒有任何警告。圖片上傳但縮略圖沒有調整大小。它存儲原始圖像 – StormTrooper
