docker - 解决方法“已安装cypress npm软件包，但缺少Cypress二进制文件。”

我正在尝试在GitLab CI运行程序中下载并安装Cypress，并得到以下错误输出：

The cypress npm package is installed, but the Cypress binary is missing.
We expected the binary to be installed here: /root/.cache/Cypress/4.8.0/Cypress/Cypress
Reasons it may be missing:
- You're caching 'node_modules' but are not caching this path: /root/.cache/Cypress
- You ran 'npm install' at an earlier build step but did not persist: /root/.cache/Cypress
Properly caching the binary will fix this error and avoid downloading and unzipping Cypress.
Alternatively, you can run 'cypress install' to download the binary again.

我运行了建议的命令cypress install，但没有帮助。接下来，它说You're caching 'node_modules' but are not caching this path: /root/.cache/Cypress 我不明白如何缓存模块并忽略其路径。接下来是You ran 'npm install' at an earlier build step but did not persist，在较早的版本中我确实有npm install，所以在这种情况下，我根据赛普拉斯官方文档中的建议将其替换为npm ci。

虽然没有解决办法。

以下是发生错误的相关行：

在Dockerfile内部：

COPY package.json /usr/src/app/package.json
COPY package-lock.json /usr/src/app/package-lock.json
RUN npm ci

在测试跑步者内部：

docker-compose -f docker-compose-prod.yml up -d --build
./node_modules/.bin/cypress run --config baseUrl=http://localhost

在package.json内部：

{
  "name": "flask-on-docker",
  "dependencies": {
    "cypress": "^4.8.0"
  }
}

有人能指出我正确的方向吗？

您可能正在两个不同的阶段运行npm install和cypress run。在这种情况下，无法保留赛普拉斯缓存，因此建议在运行CYPRESS_CACHE_FOLDER和install时使用cypress run/open选项。该命令将如下所示，

CYPRESS_CACHE_FOLDER=./tmp/Cypress yarn install

CYPRESS_CACHE_FOLDER=./tmp/Cypress npx cy run [--params]

对我有帮助

.\node_modules\.bin\cypress.cmd install --force

解决方法“已安装cypress npm软件包，但缺少Cypress二进制文件。”
