Question

我在usr / local /

中有一个标准的自制软件安装

当我尝试：

Larson-2:~ larson$ brew install postgresql
Error: Cannot write to /usr/local/Cellar

当我使用sudo时：

Larson-2:~ larson$ sudo brew install postgresql
Cowardly refusing to `sudo brew install'

我做错了什么？

Answer 1

你以某种方式对/usr/local/Cellar的权限有限。 Brew不喜欢用sudo安装，这就是它拒绝的原因。

检查权限：

ls -ld /usr/local/Cellar

打开它们写作：

sudo chmod a+w /usr/local/Cellar

Answer 2

使用sudo时不要使用brew（出于安全原因）。

您需要简单设置权限。

所以我会更进一步，将权限更改为：

sudo chgrp -R admin /usr/local /Library/Caches/Homebrew
sudo chmod -R g+w /usr/local /Library/Caches/Homebrew

然后将特定组（admin或staff）应用于应允许使用brew命令的用户。通过以下方式检查用户组：id -Gn）。

如果还有其他问题，请运行：brew doctor以查看错误。

Answer 3

我更改了群组权限：

$ chgrp -R admin /usr/local/Cellar
$ chmod g+w /usr/local/Cellar

假设您的用户帐户位于群组管理员中。

Answer 4

如果您的计算机上有多个用户，也会发生这种情况。如果是这样，最好更改用户，因为除了/ usr / local / Cellar之外，其他每种方法都会让你搞乱更多的文件和文件夹

使用su userWhoInstalledBrew。

Answer 5

可以通过将目录的所有者更改为当前用户来解决问题：

sudo chown -R $USER /usr/local

Answer 6

根据他在There is no Cellar file in my usr/local dir for brew的回答中提供的建议chukcha14，我做到了：

jaimes-mbp:SMR jaimemontoya$ brew install mongodb-community@4.2
Warning: You are using OS X 10.15.

You may encounter build failures or other breakages.

==> Caveats
To have launchd start mongodb/brew/mongodb-community at login:
  ln -sfv /usr/local/opt/mongodb-community/*.plist ~/Library/LaunchAgents
Then to load mongodb/brew/mongodb-community now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist
Or, if you don't want/need launchctl, you can just run:
  mongod --config /usr/local/etc/mongod.conf
