由于缺少模块“minizlib”而导致 npm 启动失败

Question

我从 github 克隆了一个 react-native 项目来继续工作，但 npm start 失败并显示如下：

Error: Cannot find module 'minizlib'

我尝试安装和重新安装 minizlib、npm 和 node，以及在类似问题中找到的一些可能的解决方案，但没有成功。任何帮助将不胜感激。

操作系统：Ubuntu 18.04.2

编辑： 我不太确定发生了什么，但它似乎确实有效。我今天打开了这个项目，看看是否有任何变化，并收到了一些关于漏洞的警告。为了修复它们，我重新安装了 expo-cli，现在似乎一切正常。

Answer 1

您的package.json 文件包含此内容，

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject"
  },
  "dependencies": {
    "braces": "^2.3.1",
    "expo": "^32.0.0",
    "firebase": "^6.1.0",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz",
    "react-navigation": "^3.11.0",
    "ws": "^3.3.3"
  },
  "devDependencies": {
    "babel-preset-expo": "^5.0.0"
  },
  "private": true
}

package.json 文件没有minizlib 包的条目。另外node_modules 文件夹没有minizlib 文件夹。

可能缺少安装相同的，你可以这样做，

npm install minizlib --save  //here `--save` will create entry into `package.json` file

安装此软件包后，您需要重新启动您的应用。

Answer 2

npm install -g npm@latest（更新 npm）。

rm -rf node_modules（删除现有模块）。

npm install（重新安装项目依赖）。
