“找不到对象”；在软件包构建/安装过程中 [英] "object not found" during package build/install

问题描述

我不知道要调试构建/安装软件包。通过

I'm at a loss to debug building/installing a package. Building a package "MyProjekt" through

> devtools::build("MyProjekt")

工作正常，即使

> devtools::document()
Updating MyProjekt documentation
Loading MyProjekt
Error: object 'rank' not found whilst loading namespace 'MyProjekt'

失败。

尝试安装内置的（纯R）软件包

Attempting to install the built (pure R) package

> install.packages(pkgs="./MyProjekt.tar.gz")
...
Error: package or namespace load failed for 'MyProjekt':
 object 'rank' not found whilst loading namespace 'MyProjekt'
Error: loading failed
Execution halted
...
ERROR: loading failed for 'i386', 'x64'

也会失败。

不幸的是，术语等级是我的域名，当我在该文件中搜索该词时，我会受到数百次点击。

Unfortunately the term 'rank' is a common term in my domain and I have hundreds of hits when searching in my files for that term.

我应该如何开始系统地寻找该错误的原因？

How might I start a systematic way to hunt this bug down?

推荐答案

该工具链在NAMESPACE文件中错误地生成了S3method（...）。

The toolchain mistakenly generates S3method(...) in the NAMESPACE file.

请遵循此答案并手动编辑NAMESPACE文件。将 S3方法（f）的出现替换为 export（f）。

Follow this answer and edit the NAMESPACE file by hand. Replace occurrences of S3method(f) with export(f).

我不确定这是可重复的。生成的文件似乎不仅要写入，而且还要在后续的软件包构建过程中读取（由devtools？由roxygen2？提供）。如果这对您不起作用，请添加您的评论。

I'm not certain this is repeatable. The generated files appear to be not just written, but also read during a subsequent package build (by devtools? by roxygen2?). Add your comments if this works/does not work for you.
