我已经卸载并安装了Homebrew 3次,因为它似乎永远不允许我安装任何东西,因为它在大多数安装结束时拒绝我的权限.
作为一个例子,我将发布我目前面临的这个libjpeg下载场景.
我尝试安装libjpeg并获取:
$ brew install libjpeg
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/jpeg-8d.mountain_lion.bottle.1.tar.gz
Already downloaded: /Library/Caches/Homebrew/jpeg-8d.mountain_lion.bottle.1.tar.gz
==> Pouring jpeg-8d.mountain_lion.bottle.1.tar.gz
Warning: Could not link jpeg. Unlinking...
Error: The brew link step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link jpeg'
Error: Permission denied - /usr/local/opt/jpeg
'brew link jpeg'导致
Error: Permission denied - /usr/local/opt/jpeg
这是我的酿酒医生所读的内容
$ brew doctor
Warning: "config" scripts exist outside your system or Homebrew directories.
./configure scripts often look …如何使用当前的Xcode/Mac OS X v10.8(Mountain Lion)或更高版本安装命令行构建工具？
与Xcode不同,没有安装程序(它只是一个包).
看起来所有命令行工具都在那里(在bundle中,在Contents/Developer下),但没有一个适当的环境变量设置为使用它们.
是否有一个我可以运行的脚本,它将设置我的环境以支持从命令行构建？
我不确定为什么会这样,但我不能在我的MAC OS X El Capitan中更新brew.我做了:
brew update
得到了:
warning: unable to unlink CONTRIBUTING.md: Permission denied
warning: unable to unlink SUPPORTERS.md: Permission denied
fatal: cannot create directory at '.github': Permission denied
为了解决这个问题,我放弃了上述命令,但还有其他问题:
sudo brew update

我尝试过brew update,但会显示此错误消息.

我也尝试过brew install zsh,但会显示上面的消息.
请让我知道如何修复此错误消息.
我试图让React Native第一次运行他们的hello world应用程序(AwesomeProject),我在控制台中收到此错误:

首先,我是一个移动开发人员(本机ios和android),我知道关于节点的小队.
我按照React Native 的Getting Started页面,用npm install和安装了npmnpm install -g
当我尝试单独启动节点服务器时,node server我得到了这个:
$ node server
module.js:341
throw err;
^
Error: Cannot find module '/Users/Eduardo/Documents/Code/Personal /ReactNative/AwesomeProject/server'
at Function.Module._resolveFilename (module.js:339:15)
at Function.Module._load …我需要帮助进行冲泡设置。我尝试过重新安装brew和ruby，但我觉得我只是让事情变得更糟。
