为什么需要sudo在Linux上使用leiningen（安装在/ bin中）？

Question

I installed leiningen on fedora, I followed the instruction:

1. download the script
2. Paste the script(via command line) to ~/bin (PATH)
3. Execute the script
4. Run lein(I had to did it with sudo) to self-install

but every time I want to run the "lein" command, I have to do it with "sudo".

How can i fix this? or what can i do to fix this?

Note: I installed leiningen at /bin but when i cd ~/bin as the installation guide said i get and error about the folder(not exist).

You installed it in /bin and ran it with sudo to install the lein jars initially, which means they are owned (and probably only readable) by root. You should install the script at ~/bin instead. You can fix it like this:

sudo rm /bin/lein
sudo rm ~/.lein
mkdir ~/bin
cd ~/bin
wget https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
export PATH="${HOME}/bin:${PATH}"
lein

You should also add ${HOME}/bin to your $PATH . If you are using bash, add this to ~/.bashrc :

export PATH="${HOME}/bin:${PATH}"

You can do that using echo :

echo 'export PATH="${HOME}/bin:${PATH}"' >> ~/.bashrc
