我有一个可用的 Bazel BUILD文件，如下所示：

package(default_visibility = ["//visibility:public"])\n\nload("@io_bazel_rules_docker//nodejs:image.bzl", "nodejs_image")\nload("@npm_bazel_typescript//:index.bzl", "ts_library")\n\n# TODO run jest tests and stop build if test not passes\n# TODO also run tests from dependent packages\nload("@lbm//:jest.bzl", "jest_test")\njest_test(\n    name = "test",\n    srcs = glob(\n        include = ["**/*.ts"],\n    ),\n    jest_config = "@lbm//:jest.config.js",\n    deps = [\n        "//packages/enums/src:lib",\n        "//packages/hello/src:lib",\n        "@npm//faker",\n        "@npm//@types/faker",\n        "@npm//express",\n        "@npm//@types/express",\n        "@npm//jest",\n        "@npm//ts-jest",\n        "@npm//@types/jest",\n    ],\n)\n\nts_library(\n    name = "lib",\n    srcs = glob(\n        include = ["**/*.ts"],\n        exclude = ["**/*.spec.ts"]\n    ),\n    deps = [\n        "//packages/enums/src:lib",\n        "//packages/hello/src:lib",\n        "@npm//faker",\n        "@npm//@types/faker",\n        "@npm//express",\n        "@npm//@types/express",\n    ],\n)\n\nnodejs_image(\n    name = …

问题

我有一个 Angular 9 应用程序，刚刚向组件添加了一个小型单元测试。describe但 VSCode 无法识别, beforeEach,等类型it。虽然我有一个tsconfig.spec.json文件，jasmine其types定义如下：

{
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "outDir": "./out-tsc/spec",
    "types": ["jasmine", "node", "jest"]
  },
  "files": ["src/test.ts", "src/polyfills.ts"],
  "include": ["src/**/*.spec.ts", "src/**/*.d.ts"]
}

我得到的实际错误如下：

Cannot find name 'describe'. Do you need to install type definitions for a test runner? Try `npm i @types/jest` or `npm i @types/mocha`.ts(2582)

我尝试过的（但没有成功）

1. @types/jasmine通过重新安装yarn add -D @types/jasmine
2. 添加jasmine到tsconfig.jsontypes​
3. types从tsconfig.spec.json中删除定义
4. 重新安装我的项目的所有依赖项 …

问题

我想为我的 Angular 应用程序设置 Jest 测试。所以我按照jest-preset-angular 的说明进行操作。但是当我使用 Bazel （此目标）测试应用程序时，出现以下错误：

要旨

我有一个 monorepo，我正在使用yarn 工作区和lerna来管理它。直到现在我都没有问题。我需要知道自上次发布以来所有更改的包。

问题

所以我运行lerna changed（docs），但这是它返回的内容：

info cli using local version of lerna
lerna notice cli v3.16.4
lerna info Looking for changed packages since v0.3.0
lerna info No changed packages found

同样，lerna 在运行时也找不到任何包lerna list（docs）：

info cli using local version of lerna
lerna notice cli v3.16.4
lerna success found 0 packages

好像有什么东西坏了。但是我在我的设置中找不到任何问题。
