Enable `--compressed` parameter on curl to automatically enable
compression on request content by sending coressponding header, if the
server side supports compression format like deflate or gzip, curl will
also decompress the content automatically, so there is no additional
works need to done manually on client side, but just enjoy the benifits
of bandwidth and time saving!
Take https://nodejs.org/dist/index.tab as an example which is last
modified on Tue, 14 Mar 2017 22:41:05 GMT, the compressed transmission
only take 4829 bytes howevet the not compressed on taks 48000 bytes,
which is about 10 times larger!
This feature can be traced back to Sep 3 2002, in curl commit:
- 64bbe9dfaf
So should be supported on various versions widely.
- Operating system and version: Mac OS X Mojave
- What happened? $NVM_DIR was set to nvm
- What did you expect to happen? $NVM_DIR should be set to .nvm
I added the following line from the README to my .zshrc:
```
export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
```
I couldn't figure out why nvm wasn't loading, until I realized that
`echo NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm"` outputs `NVM_DIR=nvm`.
Changing the line to `export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/}.nvm"` fixed the problem. This outputs `NVM_DIR=.nvm` as expected. I tested this and the same behavior holds true in Bash as well.
With the environment variable XDG_CONFIG_HOME set, the installation
script uses the directory $XDG_CONFIG_HOME/nvm now. Before the change
the variable's value with "/nvm" cut off was used, which usually results
in an installation without any subdirectory.
this is done by checking if the user supplies `PROFILE=/dev/null` when running `install.sh`, the `nvm_detect_profile` function will not output any strings, causing `nvm_do_install` to skip adding `SOURCE_STR`.
