error An unexpected error occurred: "EACCES: permission denied, unlink '/home/ubuntu/environment/sample_app/node_modules/.bin/acorn'".
文件的外观如下：
#!/usr/bin/env node
'use strict';
require('../dist/bin.js');
我以前没有遇到这样的问题，这是怎么回事？
更新，这是完整的错误日志：

更新 无论我做什么或键入什么，问题仍然存在。我似乎没有做任何事情的“权限”，而且我不明白为什么考虑自己可以做得到。输入 $ yarn install --check-files 命令后，我收到以下消息：
yarn install v1.22.4

看我的橡子文件，它是这样的：|
#!/usr/bin/env node
'use strict';
require('../dist/bin.js');
我不知道该怎么办。
