tox --parallel--safe-build无法与Jenkins并行管道一起使用

Question

我想在jenkins管道中并行调用python版本2.7和3.6的tox。

问题在于，tox不是线程安全的，但是似乎可以使用选项（--parallel--safe-build）解决，但就我而言不是。似乎没有效果。

可以在本地复制：

  

tox --parallel-safe-build -e py27和tox --parallel-safe-build -e py36   ＆

将在二分之一中失败。

Jenkinsfile阶段

stage("Compatibility") {
    steps {
        parallel(
            "Python 2.7": {
                sh "venv/bin/tox --parallel--safe-build -e py27"
            },
            "Python 3.6": {
                sh "venv/bin/tox --parallel--safe-build -e py36"
            }
        )
    }
}

tox.ini

[tox]
envlist = py27,py36

[testenv]
deps =
    pytest
commands =
    pytest
