无法正确加载isparta模块，因此无法运行测试用例

Question

我的测试过去运行非常好的，但是突然间我在运行测试时得到了下面的错误。请帮帮忙。我被困在上面两天了。

这是一个反应项目。我在用网络包和babel。使用isparta进行代码覆盖。

};

随着事情的发展发生了变化，它起了作用。1)从业力配置插件列表中删除“isparta”。2)我没有使用karma start，而是进行了./node_modules/karma/bin/karma启动。

这个错误是因为如果你只做karma start，你实际上是指全球安装的业力，默认情况下，你会搜索全局空间中的插件模块。这种业力，以及全球安装的插件模块都过时了，这与较新的isparta模块不起作用。
