[英]Cargo path setup for rust-racer
I just installed racer
using cargo
. 我刚用
cargo
安装了racer
。 After installing it say this: 安装后说这个:
Installing /home/karthik/.cargo/bin/racer
warning: be sure to add `/home/karthik/.cargo/bin` to your PATH to be able to run the installed binaries
How do I do this? 我该怎么做呢? Googling didn't help.
谷歌搜索没有帮助。 Also, Should I be setting a
PATH
variable for cargo bin as well? 另外,我是否应该为货箱设置
PATH
变量?
Edit: OS is Ubuntu 14.04 and I have super user access 编辑:操作系统是Ubuntu 14.04,我有超级用户访问权限
You have to add the cargo bin path to your PATH
variable and set the RUST_SRC_PATH
in .profile
or .bash_profile
. 您必须将货物仓路径添加到
PATH
变量,并在.profile
或.bash_profile
设置RUST_SRC_PATH
。
There are two steps: 有两个步骤:
(1) Add the Cargo bin to your PATH
variable. (1)将货箱添加到
PATH
变量中。 You can run $ whereis cargo
to find the bin path, and then do $ sudo -H gedit /etc/environment
where you can add that new path section to your current PATH
variable. 您可以运行
$ whereis cargo
来查找bin路径,然后执行$ sudo -H gedit /etc/environment
,您可以将新路径部分添加到当前PATH
变量中。 You will need to save and close the file (and you can ignore the error message in the terminal during the saving portion) in order for it to take effect. 您需要保存并关闭文件(并且可以在保存期间忽略终端中的错误消息)以使其生效。
(2) Run $ rustup component add rust-src
to download the necessary Rust source files for you. (2)运行
$ rustup component add rust-src
为您下载必要的Rust源文件。
At this point Racer should work properly. 此时Racer应该正常工作。
