我所有的 react-native 项目都显示错误 TypeError: cb.apply is not a function

Question

我对本机反应真的很陌生。我所有的项目早上都运行良好，但不知何故他们停止了工作。当我运行 react-native start 和 react-native run-android 时，应用程序会安装在设备上，但随后出现了这个错误，而这在以前没有发生过。

Loading dependency graph, done.
 DELTA  [android, dev] ./index.js ???????????????? 0.0% (0/1)/home/yehyaumar/Documents/dumm/busybee/node_modules/graceful-fs/polyfills.js:285
        if (cb) cb.apply(this, arguments)
                   ^

TypeError: cb.apply is not a function
    at /home/yehyaumar/Documents/dumm/busybee/node_modules/graceful-fs/polyfills.js:285:20
    at FSReqCallback.oncomplete (fs.js:169:5)

我什至从头开始克隆了 repo，但错误仍然存​​在。请帮忙。RN 版本：0.59.2

我的一个项目的 package.json 文件，

Answer 1

Ciao，这个问题与graceful-fs包有关。请重新安装graceful-fs：

npm install graceful-fs --save-dev

问题应该得到解决。

Answer 2

对我来说，npm cache clean —force没有工作，并且优雅-fs 不是我项目中的直接依赖项。

OS: Ubuntu
Node: 14.6.0 
Npm: 6.14.7

我仍然不确定为什么会出现此错误，但它有效。我在Flavio Copes 的帖子上找到了这个解决方案。

打开文件/node_modules/graceful-fs/polyfills.js，错误来自哪里。

这是给出问题的函数：

function statFix (orig) {
  if (!orig) return orig
  // Older versions of Node erroneously returned signed integers for
  // uid + gid.
  return function (target, cb) {
    return orig.call(fs, target, function (er, stats) {
      if (!stats) return cb.apply(this, arguments)
      if (stats.uid < 0) stats.uid += 0x100000000
      if (stats.gid < 0) stats.gid += 0x100000000
      if (cb) cb.apply(this, arguments)
    })
  }
}

注释掉这些行（第 62-64 行）：

// fs.stat = statFix(fs.stat)
// fs.fstat = statFix(fs.fstat)
// fs.lstat = statFix(fs.lstat)

Answer 3

我在尝试在我的一个旧项目（React Native 版本 0.59.x）上启动 react-native 开发服务器时遇到了这个问题。对我来说，修复从降级的节点版本14来10使用NVM

Answer 4

转到 C:\Users(your username)\AppData\Roaming 删除 npm 和 npm-cache

再次尝试运行，如果再次出现错误，请卸载并彻底删除Nodejs，检查上述两个文件是否仍然不存在，然后重新下载Nodejs。

在我的一台计算机上，第一种方法没有问题，第二种方法需要完全替换 Nodejs 然后才能工作。
