打开终端时出现此错误
ERROR: Directory [=] does not exist.
The prefix script allows you to manage multiple installations of
a set of software installed on the same machine. It helps in this
by taking care of the reconfiguration of environment variables
appropriate for each installation. It is assumed that the
software for each installation is all under a single directory
whose name is assigned to an environment variable called PREFIX.
This arrangement of enabling multiple installations of software
on a single machine is useful at many times. On a single server,
it can provide for development, test, and production installations
of software. Alternatively, on development servers,
it allows for multiple development "sandboxes", one for each
developer. On production servers, it allows for multiple versions
of the production software to be installed. One might be the currently
running software, one the previous software kept online as a fall-back,
and one a new release of software which is scheduled to be brought
online soon.
There are three usages of the prefix script:
(1) The interactive usage should be placed as the last line
of a user's .profile. The user must be running the
Korn shell (ksh) or the Bourne Again shell (bash).
The user is prompted to enter one of the known PREFIX locations,
specified in the $HOME/.prefixes file or the /etc/prefixes file.
During configuration, the $PREFIX/.prefixrc file is sourced
in order to accomplish environment-specific configurations.
(2) The non-interactive user configuration does not consult
$HOME/.prefixes or /etc/prefixes or prompt the user, but merely
configures the environment in accordance with the cmd line argument.
(3) The batch command usage is mainly for running commands from
cron or running commands in another environment without changing
to that environment.
Usage (1): . prefix (sets up environment)
(2): . prefix <prefix> (non-interactive setup)
(3): prefix <prefix> <cmd> <args> (runs cmd configured for PREFIX)
/usr/bin/prefix: línea 292: /home/ubuntu-user/npm-global: No such file or directory
我不明白问题出在 npm 还是环境变量上。
答案1
如果在打开终端时发生这种情况，则很可能是您的.bashrc或.profile文件中存在问题。您最近修改过它们吗？也许是在您安装 npm 时？您需要检查并修复该文件。
