找不到模塊'@babel/parser'

Question

運行babel時，我不再能夠轉換我的代碼庫。 我做了。 以前沒有發生過，我無法弄清楚為什么。 這只發生在我拉遠程 master 分支時，它有yarn.lock沖突。 我解決了與yarn命令的沖突。

這是我的package.json的一部分

{
  "devDependencies": {
    "@babel/cli": "^7.1.0",
    "@babel/core": "^7.1.2",
    "@babel/plugin-proposal-class-properties": "^7.0.0",
    "@babel/plugin-proposal-decorators": "^7.0.0",
    "@babel/plugin-proposal-export-default-from": "^7.0.0",
    "@babel/plugin-proposal-export-namespace-from": "^7.0.0",
    "@babel/plugin-proposal-function-sent": "^7.0.0",
    "@babel/plugin-transform-runtime": "^7.1.0",
    "@babel/polyfill": "^7.0.0",
    "@babel/preset-env": "^7.1.0",
    "@babel/preset-react": "^7.0.0",
    "@babel/register": "^7.0.0",
    ...
  }
}

運行babel src -d build會導致以下錯誤

{ Error: Cannot find module '@babel/parser'
    at Function.Module._resolveFilename (module.js:548:15)
    at Function.Module._load (module.js:475:25)

我還嘗試刪除node_modules並運行yarn install ，但沒有成功。

Answer 1

能夠通過簡單地將babel-eslint從8.2,3到10.0.1來解決該問題

Answer 2

這對我有用：

yarn add -D @babel/parser

或與NPM

npm i -D @babel/parser

祝你好運...

Answer 3

以下命令對我有用

npm 審計修復 --force

請注意，審計修復將 SemVer 主要更新安裝到頂級依賴項，而不僅僅是 SemVer 兼容的更新 ( https://docs.npmjs.com/cli/v7/commands/npm-audit )

Answer 4

對我來說，解決方案是刪除node_modules文件夾，然后重新安裝

rm -rf node_modules
yarn
