Question

我正在尝试使用Mocha（和Chai）来测试我的Node.js TypeScript代码。

当我使用WebStorm的Mocha运行配置时，它运行以下命令并引发错误

/usr/local/bin/node /Users/george.pai/Workspace/fd/fd-lambdas/node_modules/mocha/bin/_mocha --require ts-node/register --ui bdd --reporter "/Users/george.pai/Library/Application Support/JetBrains/Toolbox/apps/WebStorm/ch-0/173.3727.108/WebStorm.app/Contents/plugins/NodeJS/js/mocha-intellij/lib/mochaIntellijReporter.js" /Users/george.pai/Workspace/fd/fd-lambdas/src/test/slack.handler.spec.ts --grep "slack\.handler "

但是，如果我从命令行运行完全相同的命令，它可以正常工作。

这是我的运行配置（一些目录名称为隐私而混淆）

我的package.json依赖项

原来混淆可能阻碍了找到解决方案。 Mocha运行配置/Users/george.pai/Workspace/fd的工作目录是项目的根目录，但不是我的节点项目的根/Users/george.pai/Workspace/fd/fd-lambdas

将工作目录更改为正确的目录解决了这个问题。我的终端已经在正确的目录/Users/george.pai/Workspace/fd/fd-lambdas中，所以这就是它工作的原因。

WebStorm Mocha运行配置抛出错误，命令行没有
