我尝试LANG在〜/ .profile和〜/ .bash_profile中设置.两者都没有奏效.

Answer 1

在Mac OS X Sierra上对我有用的是在我的~/bash_profile文件中添加以下内容:

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

然后我重新加载了bash配置文件: source ~/.bash_profile

对于那些使用zsh的人,你必须将这些行添加到〜/ .zshrc中

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

然后我重新加载bash配置文件: source ~/.zshrc

Answer 2

对于使用 zsh 的用户，您必须将这些行添加到 ~/.zshrc

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
