不能安装drush8，有drush6

Question

我安装了drush，当我执行"drush状态“时，它说我的drush版本是6.6.0。

我希望使用drush7，所以我从github下载了它，并执行了以下命令：

chmod +x drush.phar

数独mv drush.phar /usr/本地/bin/drush

钻孔井

我得到以下错误:无法找到drush命令init。

当我做钻孔状态，它仍然说我有drush6版本.我该怎么办？

Answer 1

可以随时手动安装

# get drush latest 8 version from 
# https://github.com/drush-ops/drush/releases
# or any version that you want 
wget https://github.com/drush-ops/drush/releases/download/8.1.16/drush.phar

# make it executable
chmod +x drush.phar

# move it to home directory or any other directory
mv drush.phar ~/drush

# go to that directory
cd ~

# find out the path to the directory
pwd
# the output would look similar to this
# /home/your_user

# edit the following file 
nano .bash_profile
# or in some systems
# nano .bashrc

# add this the end of the file
alias drush='/home/your_user/drush'

# use the alias you just setup
source ~/.bash_profile

注意:上面的示例在ubuntu中工作，但在其他发行版上应该类似。

根据文档 drush 8与D8、D7和D6一起工作，所以没有理由安装drush 7。

如果您想用drush8调用它，请在.bash_profile文件中使用以下alias drush8='/home/your_user/drush'
