Question

我尝试使用rmarkdown，到目前为止我遇到了很多麻烦。第一个是当Rstudio好像应该安装新版本的软件包时。它无法超越它。我试图逐个安装所有必需的软件包，但是我收到了这个错误

我逐个安装了软件包，我可以加载它们，但它不能作为一个整体工作。文件 - ＆gt;新的 - ＆gt; rmarkdown

我最近发现我在启动Rstudio时收到了这样的消息

它让我发疯了。我卸载了“knitr”并尝试重新安装。 ERROR

您可以通过test_dict = {'path': '/home/user/user_name','device1': {'IP': '10.10.10.10','password': 'pwd1','username': 'user1','name':'USER_DEFINED'},'device2': {'IP': '11.11.11.11','password': 'pwd2','username': 'user2','name':'USER_DEFINED_TEST'}} keys_to_be_updated = "path,device1/name,device2/name" values_to_be_updated = "/home/user/user_name/ABCD,USER_TESTER1,USER_TESTER2" k = 0 list_of_values = values_to_be_updated.split(",") if keys_to_be_updated != "": for i in keys_to_be_updated.split(","): for j in i.split("/"): tmp = "['"+str(j)+"']" # test_dict[tmp] = list_of_values[k] # How to assign values to multi level dictionary here # test_dict['path'] = list_of_values[k] # test_dict['device1'][name'] = list_of_values[k] # test_dict['device2'][name'] = list_of_values[k] k = k+1告诉RStudio您图书馆的位置命令然后手动选择.libPaths()以及通过屏幕上的“软件包”窗口在RStudio中使用“rmarkdown”文档所需的其他软件包。

knitr
