安装自耕农时出错

Question

在我的OSX机器上安装Yeoman会导致以下错误:

我相信问题是bash在Ruby Version Manager中寻找npm,这是我最初安装node和npm的地方.但是,我从RVM中删除了这两个并从Node网站安装.我还调整了我的.bash_profile:

PS1="\u$ "
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"
export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"

if [ -f ~/.git-completion.bash ]; then
   source ~/.git-completion.bash
fi

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM$

我不明白为什么Yeoman安装失败了.

Answer 1

这解决了我的问题.在主目录中设置npm文件夹的权限是我的修复.

sudo chown -R `whoami` ~/.npm

Answer 2

该npm命令失败,因为您需要root用户来编辑文件/usr/.

您应该正确配置npm,请参阅相关的SO答案:

$ echo prefix = ~/.node >> ~/.npmrc

Answer 3

尝试

sudo chown -R $USER /usr/local

而这种问题将永远得到解决

没有鼓励npm与sudo
