Question

我有一个带有辅助函数的个人R包，我在各种项目中使用它。但是，我想让项目使用特定版本的项目，然后继续添加代码。我知道我可以用分支机构做到这一点，但我更喜欢用提交标签来做。

查看devtools::install_git的文档，似乎如果我标记了一个提交，那么我应该能够安装该特定提交，但这对我不起作用。

这张图片显示我的提交标记为“v0.0.1”

但是试图安装它给了我这个：

devtools::install_git(url = 'http://<username>@<company stash url>/scm/preamp.git', branch = 'v0.0.1')

# > Downloading git repo http://<username>@<company stash url>/scm/preamp.git
# > Error in .local(object, ...) : 'v0.0.1' did not match any branch

从截图中看，您的软件包可能在GitHub上？您是否能够使用install_github安装某个软件包的某个版本？在该函数中，您使用ref指定提交/标记/分支，如下所示：

> install_github("hadley/lubridate", ref = "v1.6.0")
