npm运行构建失败，并显示“错误：自定义关键字定义无效：data.errors应该为布尔值”

Question

当我尝试构建VueJS应用程序时看到npm错误。我在GitLab CI的build阶段内看到此错误。我没有找到关于错误消息的任何提及。以前，我已经能够成功运行npm run build，而且尚未对Vue应用程序代码进行任何更改，因此我不确定是什么原因导致了此错误。

这是我用于构建Vue应用程序的docker文件中的内容：

# build stage
FROM node:10.14.2-jessie as build-stage
WORKDIR /app/
COPY frontend/package.json /app/
RUN npm cache verify
RUN npm install
COPY frontend /app/
RUN npm run build

如果您使用纱线

添加到以下package.json

  "resolutions": {
    "ajv": "6.8.1"
  }

然后运行yarn install

如果您使用npm

npm uninstall ajv
npm install ajv@6.8.1

Answer 2

在节点模块中，我将ajv文件夹重命名为ajv1。现在，我将其他版本的ajv文件夹的较旧版本复制到了node-modules文件夹中。奏效了。

Answer 3

快速修复：

转到node_modules文件夹中的 ajv 依赖项：

  

node_modules / ajv / lib / keyword.js

注释第64和65行：

if (!validateDefinition(definition))
  throw new Error('custom keyword definition is invalid: '  + this.errorsText(validateDefinition.errors));

它应该没有副作用。
