尝试运行 jest 的 jest 版本不正确

Question

我在我的角度项目中有玩笑测试。

\n\n

我有一个 package.json 文件，指定我想用来运行测试的 jest 版本。该文件包括：

\n\n

"@types/jest": "^24.0.18",\n"jest": "^24.9.0",\n"jest-preset-angular": "^7.1.1",\n

\n\n

jest 配置还包括：

\n\n

"setupFilesAfterEnv": [\n  "<rootDir>/setup-jest.ts"\n],\n

\n\n

这就是问题发生的地方。当尝试跑步时jest，我收到以下消息：

\n\n

\xe2\x97\x8f Validation Warning:\n\nUnknown option "setupFilesAfterEnv" with value ["<rootDir>/setup-jest.ts"] was found.\nThis is probably a typing mistake. Fixing it will remove this message.\n\nConfiguration Documentation:\nhttps://jestjs.io/docs/configuration.html\n

\n\n

我看了一下jest -h，发现了一个标志，它为我提供了笑话环境的设置。

\n\n

jest --showConfig\n

\n\n

然而，这表明我正在版本上运行笑话

\n\n

"version": "23.6.0"\n

\n\n

所以我的问题就在这里。为什么在我做了之后npm i，尝试运行测试的笑话版本是不同的/旧的。

\n\n

我尝试使用-gflag 和save-devflag 安装 jest-cli 。

\n\n

还尝试在 VS Code 中运行测试，如果有帮助的话。

\n\n

请帮忙。

\n\n

先感谢您。

我遇到了同样的问题，经过长时间的搜索，我尝试了以下方法：

type jest

这给了我位置：

/usr/local/bin/jest

重命名该文件（或删除它），解决了问题（请注意，现在运行jest将给出command not found）。
