“超出API速率限制”尝试使用devtools :: install（）安装本地R软件包时 [英] "API rate limit exceeded" when trying to install local R package using devtools::install()

问题描述

包装开发初学者在这里！

Package development beginner here!

我正试图第一次将某些代码转换为本地R包。我使用 usethis :: create_package（）制作了一个程序包，并使用 devtools :: document（）添加了文档。

I'm trying to turn some code into a local R package for the very first time. I made a package using usethis::create_package(), added documentation using devtools::document().

现在，在玩了一段时间之后，尝试使用 devtools :: install安装最新版本时遇到了以下错误（）：

Now, after playing around with it for a while, I ran into the following error when trying to install the newest version using devtools::install():

Error: HTTP error 403.
  API rate limit exceeded for [my IP]. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)

  Rate limit remaining: 0/60
  Rate limit reset at: 2019-03-18 16:32:05 UTC

  To increase your GitHub API rate limit
  - Use `usethis::browse_github_pat()` to create a Personal Access Token.
  - Use `usethis::edit_r_environ()` and add the token as `GITHUB_PAT`.

如果我使用 devtools，问题 still 存在：install_local（ my_folder_name）。真正令我困惑的是，我试图通过安装位于本地文件夹中的软件包来达到GitHub速率限制。

The problem still exists if I use devtools:install_local("my_folder_name"). What genuinely confuses me here is that I am hitting a GitHub rate limit by trying to install a package sitting in a local folder.

我在软件包设置中犯了一个错误，还是使用 devtools :: install（）总是涉及到GitHub API？
是否可以进行任何更改以使软件包的安装过程保持本地化，从而避免速率限制问题？

Did I make a mistake in the package setup, or does using devtools::install() always involve the GitHub API? Is there anything I can change to keep the installation process of my package local and thus avoid the rate limit issue?

编辑：我的说明文件引用了其他软件包：

My DESCRIPTION file refers to other packages:

Depends: 
    R (>= 3.4.3),
    dplyr
Imports:
    RMariaDB,
    dbplyr,
    DBI,
    reshape2,
    RColorBrewer,
    knitr,
    kableExtra,
    scales,
    magrittr,
    DT,
    formattable,
    testthat,
    ggplot2,
    rmarkdown

推荐答案

似乎默认情况下， devtools :: install（） 检查在 Depends ， Imports 和 DESCRIPTION 文件中的> LinkingTo （请参阅devtools参考中的 dependencies = NA 选项的说明手册此处）。 remotes :: install_local（）也是如此， devtools :: install_local（）链接到该目录。

It seems that by default, devtools::install() checks for all packages listed as dependencies under Depends, Imports and LinkingTo in the DESCRIPTION file (see explanation of dependencies = NA option in devtools reference manual here). This is also true for remotes::install_local(), which devtools::install_local() links to.

一个解决方案是显式禁用检查程序包依赖关系：如果使用 devtools :: install（ my_local_package，依赖关系= FALSE），您不再需要连接到 api.github.com 。当您知道已经安装了必要的依赖项时，这样做很有意义，例如，您正在打包自己的代码时。

A solution to this is to explicitly disable checking package dependencies: If you use devtools::install("my_local_package", dependencies = FALSE) instead, you no longer need to connect to api.github.com. Doing this makes sense when you know you already have the necessary dependencies installed, which is the case when you're R-packaging your own code.

（还应注意： devtools :: install（）中的默认选项需要互联网连接才能安装任何软件包，但通过设置 dependencies = FALSE ，也可以离线安装本地软件包！）

(Also worth noting: The default options in devtools::install() require an internet connection for installation of any packages but by setting dependencies = FALSE, it's also possible to install a local package offline!)
