Error in installation a R package

问题:

Please help me, I cannot install "MASS" package.

> library(MASS)
Error in library(MASS) : there is no package called ‘MASS’

I tried to install MASS package from local:

> utils:::menuInstallLocal()  
package ‘MASS’ successfully unpacked and MD5 sums checked  
Warning: cannot remove prior installation of package ‘MASS’

Even I cannot remove "MASS":

> remove.packages("MASS")  
Removing package from ‘C:/Program Files/R/R-3.0.1/library’  
(as ‘lib’ is unspecified)  
Error in find.package(pkgs, lib) : there is no package called ‘MASS’

Also with this option I couldn't install package:

> options(install.lock=T)  
> utils:::menuInstallLocal()  
package ‘MASS’ successfully unpacked and MD5 sums checked  
Warning: cannot remove prior installation of package ‘MASS’  
Warning: restored ‘MASS’  
Warning message:  
In file.copy(savedcopy, lib, recursive = TRUE) :  
  problem copying C:\Program Files\R\R-3.0.1\library\00LOCK\MASS\libs\x64\MASS.dll to C:\Program Files\R\R-3.0.1\library\MASS\libs\x64\MASS.dll: Permission 

And with install.packages:

> install.packages("C:\\MASS_7.3-35.zip",repos=NULL)
package ‘MASS’ successfully unpacked and MD5 sums checked  
Warning: cannot remove prior installation of package ‘MASS’  
Warning: restored ‘MASS’  
Warning message:

I should mention I use R with ORE (Oracle R Enterprise).

There could be a few things happening here. Start by first figuring out your library location:

Sys.getenv("R_LIBS_USER")

We already know yours from the info you gave: C:\Program Files\R\R-3.0.1\library

I believe you have a file in there called: 00LOCK. From ?install.packages:

Note that it is possible for the package installation to fail so badly that the lock directory is not removed: this inhibits any further installs to the library directory (or for --pkglock, of the package) until the lock directory is removed manually.

You need to delete that file. If you had the pacman package installed you could have simply used p_unlock() and the 00LOCK file is removed. You can't install pacman now until the 00LOCK file is removed.

To install pacman use:

install.packages("pacman")

There may be a second issue. This is where you somehow corrupted MASS. This can occur, in my experience, if you try to update a package while it is in use in another R session. I'm sure there's other ways to cause this as well. To solve this problem try:

1. Close out of all R sessions (use task manager to ensure you're truly R session free) Ctrl + Alt + Delete
2. Go to your library location Sys.getenv("R_LIBS_USER"). In your case this is: C:\Program Files\R\R-3.0.1\library
3. Manually delete the MASS package
4. Fire up a vanilla session of R
5. Install MASS via install.packages("MASS")

If any of this works please let me know what worked.

I had the same problem with e1071 package. Just close any other R sessions running parallelly and you will be good to go.

回答3:

After using the wrong quotation mark characters in install.packages(), correcting the quote marks yielded the "cannot remove prior installation" error. Closing and restarting R worked.

回答4:

The solution indicated by Guannan Shen has one drawback that usually goes unnoticed. (Guannan Shen, I tried to link to you or you post, but I wasn't able.)

When you run sudo R in order to run install.packages() as superuser, the directories in which you install the library end up belonging to root user, a.k.a., the superuser.

So, next time you need to update your libraries, you will not remember that you ran sudo, therefore leaving root as the owner of the files and directories; that eventually causes the error when trying to move files, because no one can overwrite root but themself.

That can be averted by running

sudo chown -R yourusername:yourusername *

in the directory lib that contains your local libraries, replacing yourusername by the adequated value in your installation. Then you try installing once again.

In my case, I had to close R session and reinstall all packages. In that session I worked with large tables, I suspect this might have had the effect.

In my case, the installation of nlme package is in trouble:

mv: cannot move '/home/guanshim/R/x86_64-pc-linux-gnu-library/3.4/nlme' 
to '/home/guanshim/R/x86_64-pc-linux-gnu-library/3.4/00LOCK-nlme/nlme': 
Permission denied

Using Ubuntu 18.04, CTRL+ALT+T to open a terminal window:

sudo R
install.packages('nlme')
q()
