问题描述
我正在使用基于Ubunt 17.04的Linux 18.当我运行rails assets:precompile时，出现以下消息Yarn executable was not detected in the system
I am using Linux 18 based on Ubunt 17.04.When I run rails assets:precompile I get the following message Yarn executable was not detected in the system
当我按照此帖子中的说明进行安装时，或在网页上，我成功安装了Yarn，但是rails不断给我错误
When I follow the instruction for the installation like in this Post or on the Webpage, I install Yarn successfully, but rails keeps giving me the error
我注意到 node.js 具有最高版本为17.2的Linux Mint的系统软件包，我尝试按照Yarn页的说明进行操作，并手动安装已安装在系统中的node.js.
I notice that node.js has system packages for Linux Mint up to version 17.2 , I tried to do all the instruction for the Yarn page and install manually node.js which was already installed in my system.
该消息并不能真正说明问题.如果我运行yarn --help，它可以工作，而我的yarn --version是0.22
The message is not really explanatory of the problem. If I run yarn --help it works and my yarn --version is 0.22
这是我的Linux Mint系统

更新
Update
这是终端/opt/yarn-0.22/bin中我的回声$PATH的输出，但是当我转到该路径时，没有文件夹/opt/yarn-0.22，因此我需要了解它的安装位置并正确配置
This is the output of my echo $PATH in the terminal /opt/yarn-0.22/bin, but when I go to that path, there is no folder /opt/yarn-0.22 so I need to understand where it was installed and configure correctly the PATH SETUP
Path Setup
If you chose manual installation, the following steps will add Yarn to path variable and run it from anywhere.
Note: your profile may be in your .profile, .bash_profile, .bashrc, .zshrc, etc.
Add this to your profile: export PATH="$PATH:/opt/yarn-[version]/bin" (the path may vary depending on where you extracted Yarn to)
In the terminal, log in and log out for the changes to take effect
To have access to Yarn’s executables globally, you will need to set up the PATH environment variable in your terminal. To do this, add export PATH="$PATH:`yarn global bin`" to your profile.
