小编Gre*_* R.的帖子

I'm trying to keep my electron app from being able to start more than one window at a time. I've already tried this, but it makes the first window opened close itself instead of the second window opened, and it completely stops working for the third window:

app.requestSingleInstanceLock();
app.on('second-instance', () => {
    app.quit();
});

The older app.makeSingleInstance also throws an error since it's deprecated. What should I do instead?

我最近打开 vscode，当我突出显示缩进时看到这个箭头出现。
我认为这与我使用的字体有关。我该如何隐藏它？
