问题描述
R包运行良好（并通过了CRAN检查），但是当Travis CI运行单元测试时，它会出现
An R package works fine (and passes CRAN checks), but when Travis CI runs unit tests it errors with
Error: Required package curl not found. Please run: install.packages('curl')
Execution halted
这似乎是Ubuntu特有的问题。我可以看到运行 sudo apt -get install libcurl4-openssl-dev 可以解决此问题。问题是我无法访问Ubuntu控制台（因为Travis CI在推送到git后会执行所有操作）-我可以将此代码放在某个地方吗？例如。能否以某种方式进入 .travis.yml ，如果可以，如何？
This seems to be an issue particular to Ubuntu. I can see here that running sudo apt-get install libcurl4-openssl-dev can fix the issue. The trouble is I don't have access to the Ubuntu console (as Travis CI does everything after I push to git) - can I place this code somewhere? E.g. can it go in .travis.yml somehow, and if so, how?
当前的 .travis.yml 文件只有2行，看起来像这样
The current .travis.yml file is just 2 lines and looks like this
language: R
cache: packages
注意
基于问题/答案，我尝试调整 .travis.yml 到
Note
Based on this question/answer, I tried adjusting .travis.yml to
language: R
cache: packages
before_install:
- sudo apt-get install libcurl4-openssl-dev
I可以从生成日志中看到 sudo apt-get install libcurl4-openssl-dev 运行了，但是无论如何，生成错误都与以前相同
I can see from the build logs that sudo apt-get install libcurl4-openssl-dev ran, but the build errored in the same way as before regardless
我也尝试过
language: R
cache: packages
before_install:
-sudo apt-get update
基于o n 建议，但存在相同的错误持续
Based on this suggestion, but the same error persisted
推荐答案
问题通过在导入中添加 curl 而消失了（即在 DESCRIPTION ）中
The problem went away by adding curl to imports (i.e. in DESCRIPTION)
例如
导入：dplyr，gsubfn，stringr，purrr，jsonlite，统计信息，lubridate，curl
如果您在 testthat 中有一个帮助文件，请不要忘记也将软件包加载到那里，即库（卷曲）。然后测试应该能够按预期运行
If you have a helper file in testthat, don't forget to load the package there too i.e. simply library(curl). Then the tests should be able to run as expected
这篇关于错误：找不到所需的包装卷曲。请运行：install.packages（'curl'）在Travis CI上停止执行的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
