安装时错误

Question

当我尝试通过此命令安装less:

npm install less .

我收到一个错误:

npm ERR! Error: EROFS, symlink '../less/bin/lessc'
npm ERR! If you need help, you may report this *entire* log,

我正在使用debian wheezy,我从源代码安装了节点.

尝试使用--no-bin-link标志再次运行安装.

npm install --no-bin-link less .

执行正常安装时,结构如下所示:

.
??? node_modules
    ??? .bin
    ?   ??? lessc
    ??? less

所有--no-bin-link标志都删除了符号链接:

node_modules/.bin/lessc --> node_modules/less/bin/lessc

该lessc可执行文件仍然可以使用:

.
??? node_modules
    ??? less
        ??? bin
            ??? lessc

以上所有想法都来自您的具体错误:

Error: EROFS, symlink

但更一般地说,EROFS错误只是意味着"错误:只读文件系统",因此您可能只需要更改您正在运行install命令的目录的权限,或者以root身份运行它sudo.
