我在Red Hat服务器上使用Ruby on Rails。 当我尝试生成控制器文件时,我收到了这个错误:
[ec2-user@ip-172-31-22-128 testApp4]$ rails generate controller welcome

我通过运行
解决了这个问题sudo chmod -R 1777 /tmp
希望这能帮助像我这样不喜欢停用弹簧宝石的其他人

需要所有权来为每个服务器启动写入重写pid。
我必须用完整的本地路径运行它&amp;须藤
$ sudo chmod -R 777 / Users / MyName / Desktop / projects / my_project / tmp /
答案 2 :(得分:5)
我看了一下试图编写pid文件的库lib/spring/env.rb
。
有问题的函数每次尝试在同一位置创建一个临时目录,除非设置了XDG_RUNTIME_DIR
:
path = Pathname.new(File.join(ENV['XDG_RUNTIME_DIR'] || Dir.tmpdir, "spring"))
将所述变量设置为唯一目录对我来说很有用:
export XDG_RUNTIME_DIR=/tmp/`whoami`
答案 3 :(得分:3)
缺少tmp文件夹的可写权限。运行chmod 777 tmp/
答案 4 :(得分:0)
或者,
export XDG_RUNTIME_DIR=/run/user/${id -u}
更改此系统变量。 id -u
返回您的UID(用户ID),这是您可以在/run/user/
下有权写入/读取的目录名称。

在Ubuntu 20.04中使用Rails 6应用程序时,我遇到了同样的问题。
每次我运行命令rails assets:clobber
完全删除public/assets
中的旧资产时,都会收到错误消息:
errno :: enotempty:目录不为空@ dir_s_rmdir
errno :: eacces:权限被拒绝@ apply2files
日志将指向导致该文件的文件的路径,在我的情况下,该文件就是public/packs/manifest.json
文件。
我尝试删除它或更改权限,但是没有任何效果。我还尝试了删除项目中的tmp
目录,但没有成功。
这是我修复的方式:
我使用ls -lh
命令列出了该目录中的所有文件和目录,这给了我以下输出:
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 1.7K Oct 6 20:29 404.html
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 1.7K Oct 6 20:29 422.html
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 1.6K Oct 6 20:29 500.html
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 0 Oct 6 20:29 apple-touch-icon.png
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 0 Oct 6 20:29 apple-touch-icon-precomposed.png
drwxr-xr-x 3 promisechukwuenyem promisechukwuenyem 4.0K Oct 13 09:20 armstrong_tools
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 0 Oct 6 20:29 favicon.ico
drwxr-xr-x 3 root root 4.0K Oct 8 13:06 packs
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 99 Oct 6 20:29 robots.txt
我意识到对文件和目录的权限很好,但是packs
目录具有root
所有权,这与允许其他文件和目录是分开的:
drwxr-xr-x 3 root root 4.0K Oct 8 13:06 packs
我只需运行以下命令即可将所有权从root更改为promisechukwuenyem:
sudo chown -R promisechukwuenyem:promisechukwuenyem packs/
现在,当我运行命令rails assets:clobber
来完全删除public/assets
中的旧资产时,它工作正常。
仅此而已。
我希望这会有所帮助

我在使用 rails server
时遇到这种类型的错误(权限被拒绝 @ apply2files)。
sudo rails server
解决我的问题。
