rails assets:预编译系统中未检测到Yarn可执行文件

Question

我正在使用基于Ubunt 17.04的Linux 18.当我跑步时,rails assets:precompile我得到以下消息Yarn executable was not detected in the system

当我按照本帖子或网页上的安装说明进行操作时,我成功安装了Yarn,但rails一直给我错误

我注意到node.js有Linux Mint的系统包到版本17.2,我试图对Yarn页面执行所有指令并手动安装node.js已安装在我的系统中.

该消息并不能解释问题.如果我运行yarn --help它是有效的,我的yarn --version是0.22

这是我的Linux Mint系统

更新

这是我$PATH在终端中回显的输出/opt/yarn-0.22/bin,但当我走到那条路径时,没有文件夹,/opt/yarn-0.22所以我需要了解它的安装位置并正确配置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.
