Python 3的tox调用失败

概述tox运行我的 Python 2.7测试,但是Python 3.4失败了.它给出了“调用失败”消息.摘录： py34 create: /home/josh/code/ezoutlet/.tox/py34ERROR: invocation failed (exit code 1), logfile: /home/josh/code/ezoutlet/.tox/py34/log/py34-0.log tox运行我的 Python 2.7测试,但是Python 3.4失败了.它给出了“调用失败”消息.摘录：

然后

解决方法 您需要查看错误消息的详细信息.注意失败的命令(来自第一个摘录)：

cmdargs: ['/usr/bin/python','py34']

您可以使用以下方式手动运行：

/usr/bin/python -m virtualenv --python /usr/bin/python3.4 py34

假设你看到同样的错误,你的问题是使用virtualenv而不是tox.

我查看了virtualenv帮助页面,看起来这应该有效.面对可能的错误,首先要升级Python,virtualenv或其他库.

就我而言,升级virtualenv是解决方案：

pip install --upgrade virtualenv

有趣的是,这个解决方案适用于@R_404_5087@和linux.最有可能的是,当我获得virtualenv和最新版本之间存在错误修复.
