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'

我究竟做错了什么？

您不知何故对/usr/local/Cellar. Brew 不喜欢使用 sudo 安装，这就是它拒绝的原因。

检查权限：

ls -ld /usr/local/Cellar

打开它们进行写作：

sudo chmod a+w /usr/local/Cellar

sudo使用时请勿使用brew（出于安全原因）。

您必须简单地设置您的权限。

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）应用于应该允许使用brew命令的用户。通过以下方式检查您的用户组：) id -Gn。

如果还有其他问题，请运行：brew doctor查看问题所在。

我会更改组权限：

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

假设您的用户帐户在组管理员中。

如果您的机器上有多个用户，也会发生这种情况。如果是这样，最好更改用户，因为其他所有方法都会让您处理更多的文件和文件夹，而不仅仅是 /usr/local/Cellar

使用su userWhoInstalledBrew.

可以通过将目录的所有者更改为当前用户来解决该问题：

sudo chown -R $USER /usr/local

有趣，但Error: Cannot write to /usr/local/Cellar由于磁盘空间不足，我收到了消息..：/（还剩 18MB）

按照 chukcha14 在There is no Cellar file in my usr/local dir for brew的回答中提供的建议，我这样做了：

jaimes-mbp:SMR jaimemontoya$ brew install mongodb-community@4.2
Warning: You are using OS X 10.15.
We do not provide support for this pre-release version.
You may encounter build failures or other breakages.
Error: Could not create /usr/local/Cellar
Check you have permission to write to /usr/local
jaimes-mbp:SMR jaimemontoya$ sudo mkdir /usr/local/Cellar

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
