我有一个方法如下，它已经正常运行了很长时间：

private String loadFromFile(){

    RandomAccessFile inFile = null;
    FileChannel inChannel = null;
    StringBuilder sb = new StringBuilder();
    try {

        inFile = new RandomAccessFile(this.latestImageFile, "r");
        inChannel = inFile.getChannel();

        ByteBuffer bb = ByteBuffer.allocate(2046);
        while( inChannel.read(bb) != -1){
            bb.flip();

            while(bb.hasRemaining()){
                char c = (char) bb.get();   // read character at current position and set the pointer to current position + 1
                sb.append(c);
            }

            bb.clear();
        }

    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (inChannel != null) try {inChannel.close(); } catch (IOException e){} …

我正在尝试使用 npm 为我的 React Native 应用程序安装 Realm。但是，我没能成功。

我的环境/设置是：

• 视窗 10
• Node.js v12.13.0
• npm v6.13.0

我一直在尝试使用这个命令：
npm install --save realm

或指定版本号：
npm install --save realm@3.6.0

但根本没有运气。以下错误消息总是提示没有明确提示给我：

> realm@3.6.0 install C:\Projects\<ProjectFolder>\node_modules\realm
