已安装，只是未链接 [英] Installed, just not linked

问题描述

注意:我不太擅长使用shell.

Note: I'm not so good at using shell.

我试图在优胜美地上使用brew安装Valgrind.

I was trying to install Valgrind using brew on Yosemite.

brew install --HEAD valgrind

最后，我遇到了与链接有关的错误，因此当我尝试重新安装时，我得到了:

Towards the end, I got an error having to do with linking so when I tried to reinstall, I got:

警告:已安装valgrind-HEAD，但尚未链接

Warning: valgrind-HEAD already installed, it's just not linked

显然，我已经安装了它.然后根据其他SO问题和答案，我尝试了:

So apparently I've already installed it. Then based on other SO questions and answers, I tried:

brew link valgrind

这似乎解决了其他人链接已安装软件的问题，但这给了我一个错误:

This seemed to solve other people's problems with linking an already installed software but this gave me an error:

Linking /usr/local/Cellar/valgrind/HEAD... 
Error: Could not symlink lib/pkgconfig/valgrind.pc
/usr/local/lib/pkgconfig is not writable.

我也尝试更新brew，但没有解决问题.如果它不是可写的，也许sudo会给我许可，但是我不想在不完全知道自己在做什么的情况下使用sudo.

I also tried to update brew but it didn't solve the issue. If it is not writable, maybe sudo would give me permission but I don't want to use sudo without knowing exactly what I am doing.

发生了什么以及如何解决?

What is happening and how to I fix it?

推荐答案

看起来像是权限问题.我会尝试这样做

Looks like a permission issue. I would try doing this

chmod 755 /usr/local/lib/pkgconfig

这应该使它可用，然后尝试

This should make that available, then try

brew link valgrind

如果这不起作用，我会尝试对其进行检查

If that doesn't work I would try doing a check on it

brew doctor
