fail to install into R 3.6.2 (windows).

[amenokoyushi]

Dear author,
I am trying to install rlang 0.4.3 into R 3.6.2. But failed, any help?
nevertheless, the former rlang 0.4.2 can be installed correctly.

install.packages("rlang")

There is a binary version available but the source version is later:
binary source needs_compilation
rlang 0.4.2 0.4.3 TRUE

installing the source package ‘rlang’

Try removing 'D:/Program Files/R/R-3.6.2/library/00LOCK-rlang'

Have you tried this?

Note that this probably indicates some prior attempt of installation failed for another reason. This comment might be helpful. rstats-wtf/what-they-forgot#62 (comment)

thank you for your reply.
I have removed the package, restarted the system, even reinstall R studio and R, and change computers.
Then, I found that if I use R-3.6.1 or below, the installation works well without any problem.
I am not very familiar with codes, however, what I wonder is whether this rlang 0.4.3 supports R-3.6.2.

It is very unlikely that R-3.6.2 would be incompatible. Have you removed the LOCK folder prior to reinstalling? This lock folder will prevent any further installation. Also make sure no R session is running, and make sure with sessionInfo() rlang is not loaded before installing. See the link that Hiroaki posted.

Now i have removed 0000LOCK-rlang folder as below.

remove the former version of rlang and check there is no rlang

install the package use install.package and select yes to install with compilation

it didnot work yesterday. but today, it is work now. and I found the new version comes to be rlang 0.4.4. thank you for your replies.
