trouble installing slidify

[chenzhih03]

Hi, ramnathv,
I have trouble installing slidify, "the slidify package is not available for 3.3.1" after runing install.packages("slidify"). Then I installed devtools and followed your recommendation:

pkgs <- c('ramnathv/slidifyLibraries', 'ramnathv/slidify')
devtools::install_github(pkgs, force = TRUE)

Now the error massage is
"** preparing package for lazy loading
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called 'stringi'
ERROR: lazy loading failed for package 'slidify'

• removing 'C:/Users/*/Documents/R/R-3.3.1/library/slidify'
  Error: Command failed (1)"

Can you please help me identify this problem? Thanks!

As the error message states, you are missing the package stringi. Install stringi first and then install slidify.

Hi ramnathv,

I have successfully installed slidify on mac, but am unable to install slidifylibraries. I have tried using the following commands:

• install_github('ramnathv/slidifylibraries')

• pkgs <- c('ramnathv/slidifyLibraries')

  devtools::install_github(pkgs)

but each time I get the following message:

• Skipping install of 'slidifyLibraries' from a github remote, the SHA1 (dbd065f4) has not changed since last install.
  Use force = TRUE to force installation

What does this message mean? Does is mean that slidifylibraries is already installed, or if not how am I supposed to input the correct command?

Any help would be greatly appreciated!

It means that slidifyLibraries is already installed. You can pass the argument force = TRUE to force it to reinstall.

Hi, Ramnathv,
Would like to thank your for your great support and ask a following up question.
When I tried to install Slidify, the issue seems very strange.

> devtools::install_github(pkgs, force = TRUE)

I get the same error as @GreenEric :

Error: ERROR: cannot cd to directory 'C:/Users/...' is not recognized as an internal or external command,
operable program or batch file.
Error: Command failed (1)

Any suggestions?

Hi ramnathv,

I had the same problem for over a day trying to install slidify, thankfully, these codes worked for me.

install_github('ramnathv/slidify',ref='dev')
install_github('ramnathv/slidifyLibraries',ref='dev')
