npm install sails尝试在1.7.5版本中安装更少

Question

我用；node -v 0.12.2和npm -v 2.7.4在Ubuntu上安装了sails。

npm install sails错误；

sails@0.11.0 preinstall /home/ubuntu/sails/node_modules/sails
node ./lib/preinstall_npmcheck.js

似乎指向了低于1.7.5的旧版本。我能够以2.5的速度使用npm install less

我在Sails' github repo上开了一期。其他细节正在开发中。

Answer 1

错误code EJSONPARSE是package.json的问题。安装节点包时，它会将package.json文件存储在.npm文件夹中。您的.npm文件夹中似乎下载了一个损坏的1.7.5以下的软件包文件。

运行以下命令：

sudo rm -rf /home/ubuntu/.npm/less/1.7.5/

这删除了您计算机上的本地less package.json文件，以便它从NPMs服务器中提取。现在，您可以再次尝试安装Sails。

错误消息将包含以下消息-

npm错误！无法解析json

npm错误！无数据，1:1输入为空

npm错误！

npm错误！^

npm错误！文件: /home/user/path_to_corrupted_file

使用此路径删除损坏的文件，然后再次运行npm安装。
