python - 创建 lib64 符号链接的 Tox 条件

问题描述

我有两个虚拟环境，都具有相同版本的 tox (3.13.2) 和相同的 python (2.7.5)。使用相同的 tox.ini 文件，我得到两种不同的行为：在一种情况下，有一个 lib64 符号链接，在另一种情况下没有。

是什么导致 tox 创建它？

Tox.ini 内容如下：

设置运行时环境

[tox]
envlist = env
minversion = 1.7.0
toxworkdir = {toxinidir}/virtenv
skipsdist = True

[testenv:rprs-env]
setenv=
    VIRTUAL_ENV = {envdir}
    PIP_USE_WHEEL= true
    PIP_NO_INDEX = true
deps = -r{toxinidir}/tox/requirements-pinned.txt
install_command = pip install --pre --find-links={toxinidir}/tox/wheelhouse {packages}

命令行显示：

test-devtree-Sxi7_C_t(feature/DTD-12|+4); ~/.virtualenvs/test_rprs_bootstrap/bin/tox -c tox.ini -r
env recreate: /home/usr/repos/test-devtree/Run/virtenv/env

解决方案

☠ pyenv 是罪魁祸首！

如果您使用本地安装的版本，然后安装 tox，然后使用该 tox，则不会lib64创建符号链接。但是，如果您指定pyenv local system为要使用的 Python 版本，则使用以下命令创建您的 pipenv 虚拟环境

pipenv install --ignore-pipfile --python=/usr/bin/python

你应该得到 tox 来创建一个lib64符号链接。

一个更好的解决方案（20/20 后见之明）是不要依赖lib64Python……</p>
