Question

这是我的Jenkins文件。

mapData

当我在Jenkins中运行它时，我得到了以下

pipeline {
    agent none
    stages {
        stage('Build') {
            agent {
                docker {
                    image 'python:3-alpine'
                }
            }
            steps {
                sh 'pip install --user -r requirements.txt'
                sh 'python WebChecker.py'
            }
            post {
                always {
                    junit 'output.xml'
                }
            }
        }
    }
}

然后我做sudo pip install ....

我收到以下错误：

[urltester] Running shell script

script returned exit code 1

然后我删除了sudo并尝试使用虚拟环境：

[urltester] Running shell script

+ sudo python -m pip install --user -r requirements.txt

/Users/me/.jenkins/workspace/urltester@tmp/durable-e36d9731/script.sh: line 1: sudo: not found

script returned exit code 127

但是当我尝试sudo时，我得到了同样的东西，但这次没有找到virtualenv。

我的最终目标是能够运行我的python脚本。这个python脚本将在同一目录中生成一个xml文件。然后Jenkins应该读取这个xml文件。我尝试过使用Docker，但没有达到目的。那我该怎么办？

Answer 1

tftd写道，将HOME更改为可写目录，例如：

MethodError: gradient(::Array{Int64,1}, ::Array{Int64,1}) is ambiguous. Candidates:
  gradient(f, x::Union{Array{T,1}, T}) where T<:Number in Calculus at /Applications/JuliaPro-0.6.4.1.app/Contents/Resources/pkgs-0.6.4.1/v0.6/Calculus/src/derivative.jl:17
  gradient(F::AbstractArray{T,1} where T, h::Array{T,1} where T) in Base.LinAlg at linalg/dense.jl:186
Possible fix, define
  gradient(::AbstractArray{T,1} where T, ::Array{T<:Number,1})

Stacktrace:
 [1] gradient(::Array{Int64,1}) at ./linalg/generic.jl:282

Answer 2

您需要将virtualenv添加到PATH变量。

如果您使用pip install virtualenv进行安装，则会在pythonX.X/Lib/site-packages/

中

Sudo也应添加到PATH变量中。

第一个代码段中的错误是因为您没有权限写入'/.local'。尝试将其作为管理员

运行

Answer 3

尝试像这样添加参数 -u root：root ：

withDockerContainer(image: 'python:3.6', args:'-u root:root'){
        sh """
            pip install --user -r requirements.txt
            python WebChecker.py
        """
    }

Answer 4

我现在遇到这个问题。 OP的原始文章中未显示的是Jenkins用于运行Docker的命令。原来是：

docker run -t -d -u XXX：YYY -w / var / lib / jenkins / workspace /

其中XXX是运行jenkins的用户的UID，而YYY是组ID。在python容器中，无法识别此UID，因此没有主目录。当'pip install --user'尝试运行时，由于没有主目录，因此默认为'/'，这是不可写的。

我认为这是詹金斯的谬论（请参阅https://issues.jenkins-ci.org/browse/JENKINS-47026）。那里的其他CICD服务似乎都可以解决这个问题。

中山洋一的答案对我有用，我对此表示反对。

Pip安装不与jenkins一起工作？
