Python Tox“；错误：找不到文件：<；项目名称>&引用；

我正在运行一个基于tox的超级简单的

tox.ini

文件和一个名为。问题是每次我运行

tox

命令时，都会出现一系列调用错误和“ERROR:file not found:

tox.ini

： CLI： 在此期间，

tox.ini

设置中的第一行项目之一是写入与跳过创建

sdist

有关的行，这被认为是“昂贵的”：

如果您的测试依赖于导入您的包，那么这是非常重要的一步（提示：他们几乎必须这样做。否则，他们测试的是什么？）。视频的讲述者（也是项目的主要贡献者）确实提到以“开发”模式安装包（

pip install-e.

），但忽略了提及（或者我听错了）包确实需要在某个时候安装

将此值更改为

skipsdist=false

或简单地删除该行即可完全修复此问题

# test suite on all supported python versions. To use it, "pip install tox"
