###### tags: `Ubuntu` `R Language` `資料科學自學園`
You find the answer in your error message:
```
------------------------ ANTICONF ERROR ---------------------------
Configuration failed because libcurl was not found. Try installing:
* deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
....
....
```
Copy and paste the following to your Terminal and than try installing tidyverse again. Should solve the problem.
```
# Required for many packages
sudo apt-get install -y libxml2-dev libcurl4-openssl-dev libssl-dev
```

## another way
It seems that to get predictive results you may want to start with renaming your existing R personal library with:
`mv /home/$USER/R /home/$USER/R_old`
Also install development package of curl:
`sudo apt-get install libcurl4-openssl-dev`
And then try to install your R-package from R-terminal:
```
$ R
install.packages("forecast")
```
