发生了什么，我该如何解决？谢谢 ！！！它困扰了我很久......

Answer 1

我遇到了类似的问题。 解决方案是改变主题！

尝试以下操作：

1. 打开 JMeter -> 选项 -> 外观 -> 选择 Darcula 以外的任何其他主题。
2. 重启 JMeter。

Answer 2

我面临同样的问题（macOS Big Sur，版本 - 11.2.3 和 Jmeter 版本 5.4.1）。我正在按照这一步“打开 JMeter -> 选项 -> 外观 -> 选择系统”及其作品

Answer 3

通常情况下，如果不存在Dependent jar，或者如果存在具有不同实现的冲突jar，则会发生这种情况。

Answer 4

我面临同样的问题（即没有一个选项像保存、合并等那样有效）。解决方案是改变主题。

尝试以下操作：

**打开 JMeter -> 选项 -> 外观 -> 选择 Darcula 以外的任何其他主题。

重启 JMeter。**
