NPM运行构建失败，出现“Error：自定义关键字定义无效：data.errors应该是布尔”

Question

当我尝试建立一个VueJS应用我看到有NPM错误。我看到这个错误在GitLab CI一build阶段内。我一直没能找到错误消息的任何提及。我以前已经能够成功运行npm run build，我还没有作出了Vue的应用程序代码做任何修改，所以我不能确定什么可能会造成这个错误。

以下是我在被用于构建应用程序的Vue我搬运工文件：

# 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

If you use yarn

添加下面的package.json

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

然后运行yarn install

if you use npm

npm uninstall ajv
npm install [email protected]

Answer 2

在节点模块我改名ajv文件夹ajv1。现在，我从其他安装复制旧版本ajv夹到节点模块文件夹。有效。

Answer 3

快速解决：

转到您node_modules文件夹中的ajv依赖性：

node_modules / ajv / LIB / keyword.js

注释掉线64和65：

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

它应该工作没有副作用。
