Question

我从github克隆了一个react-native项目进行工作，但是npm start失败并显示以下内容：

Error: Cannot find module 'minizlib'

我尝试安装和重新安装minizlib，npm和node，以及在此处类似问题中发现的少数可能解决方案，但没有成功。任何帮助将不胜感激。

操作系统：Ubuntu 18.04.2

link to github repo

编辑：我不太确定发生了什么，但是它确实可以正常工作。我今天打开了该项目，以查看是否有任何更改并收到有关该漏洞的一些警告。为了解决这些问题，我重新安装了expo-cli，现在似乎一切正常。

Answer 1

npm install -g npm@latest（更新npm）。

rm -rf node_modules（以删除现有模块）。

npm install（重新安装项目依赖项）。

Answer 2

您的package.json文件包含此文件，

{
  "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软件包的条目。另外，node_modules文件夹没有minizlib文件夹。

可能缺少安装相同的软件的方法，

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

安装此软件包后，您需要重新启动应用程序。

npm启动失败，因为缺少模块'minizlib'
