“ npm run build” =“反应脚本:权限被拒绝”

jenkins

我正在尝试在Ubuntu 18.04上部署可正常运行的Windows 10 Spring-Boot /
React应用程序,但是尽管进行了无数次尝试修复,但仍会出现“ react-scripts:Permission
denied”错误。希望你们中的一位反应专家可以发现我的错。

我的package.json看起来像这样

{
  "name": "medaverter-front",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.3.2",
    "@testing-library/user-event": "^7.1.2",
    "axios": "^0.19.2",
    "bootstrap": "^4.4.1",
    "react": "^16.13.0",
    "react-dom": "^16.13.0",
    "react-router-dom": "^5.1.2",
    "react-scripts": "3.4.0",
    "react-table-6": "^6.11.0",
    "react-validation": "^3.0.7",
    "reactstrap": "^6.5.0",
    "validator": "^12.2.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我以root用户身份登录,并使用nvm来安装node和lts。我这样安装nvm:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash

然后这样做:

nvm install node
nvm use node
nvm install --lts
nvm use --lts

然后,我cd/var/lib/jenkins/workspace/MedAverter/medaverter- front安装node_modules这样的:

npm install -g

然后将其递归更改为777,如下所示:

chmod -R 777 node_modules

我还递归地将所有/root/.nvm权限更改为777,如下所示:

chmod -R 777 /root/.nvm

我可以使用一次构建它

npm run build

但是后来我从詹金斯那里运行了“立即构建”,但失败了

[[1;34mINFO[m] Running 'npm run build' in

/var/lib/jenkins/workspace/MedAverter/medaverter-front
[[1;34mINFO[m] [[1;34mINFO[m] > medaverter-front@0.1.0 build
/var/lib/jenkins/workspace/MedAverter/medaverter-front
[[1;34mINFO[m] > react-scripts build [[1;34mINFO[m]

[[1;31mERROR[m] npm ERR! medaverter-front@0.1.0 build: react-scripts build
[[1;31mERROR[m] npm ERR! Exit status 126

然后我cd/var/lib/jenkins/workspace/MedAverter/medaverter-front跑步

npm run build

并且也再次得到相同的错误:

> sh: 1: react-scripts: Permission denied npm ERR! code ELIFECYCLE
> npm ERR! errno 126 npm ERR! medaverter-front@0.1.0 build:
> react-scripts build npm ERR! Exit status 126

我花了几天的时间试图弄清楚这一点。有什么建议吗?

我终于找到了解决这个问题的方法。花了几天的时间。首先,我删除了Jenkins项目,并使用Pipeline而不是Freestyle创建了一个新项目。然后,我添加了带有脚本的Jenkinsfile。那继续失败,但是现在我可以灵活地添加其他命令来处理错误。

一个新的错误是关于玩笑的工人。我在DigitalOcean服务器上运行了以下命令以超越该命令:

yarn add jest-worker

然后我又遇到了旧的权限错误。我认为所有这些权限错误都是由于用户jenkins试图运行root用户拥有的内容而引起的,即使所有内容都具有777权限。我不明白,但这就是我的解决方法。修改/
etc / sudoers文件并添加以下行:

jenkins ALL=(ALL) NOPASSWD:ALL

然后修改Jenkins文件脚本,以包括递归chmod和chown。这是最终工作的完整脚本:

pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                echo 'Checkout...'
                sh 'sudo chmod -R 777 /var/lib/jenkins/workspace/MedAverter/medaverter-front'
                checkout scm
                sh 'sudo chmod -R 777 /var/lib/jenkins/workspace/MedAverter/medaverter-front'
                sh 'sudo chown -R jenkins /var/lib/jenkins/workspace/MedAverter/medaverter-front'
                stash 'sources'
            }
        }
        stage('Build') {
            steps {
                echo 'Build...'
                unstash 'sources'
                sh 'sudo chmod -R 777 /var/lib/jenkins/workspace/MedAverter/medaverter-front'
                sh 'sudo chown -R jenkins /var/lib/jenkins/workspace/MedAverter/medaverter-front'
                sh 'mvn clean package -DskipTests'
                stash 'sources'
            }
        }
    }
}

我还不得不将DigitalOcean
Droplet的内存从1GB增加到2GB,以克服另一个错误。如果有人知道更好的方法来克服令人沮丧的权限错误,请发表评论。
