拒绝安装sqlite3作为自身的依赖

Question

我有最新版本的node.js构建没有问题.我正在尝试为node.js使用sqlite模块.

对于developseed的node-sqlite3,我按照指示:

git clone git://github.com/developmentseed/node-sqlite3.git
cd node-sqlite3
./configure
make

我安装了npm:curl -k https://npmjs.org/install.sh | sudo sh

并使用npm安装node-gyp:sudo npm install -g node-gyp

在node-sqlite3 configure-d和make-d之后,我尝试用npm安装,我得到这个:

npm install sqlite3
npm WARN install Refusing to install sqlite3 as a dependency of itself

当我研究这个错误时,我发现了这个问题:npm install sqlite3 error我试过:

 node-waf clean || true; node-waf configure build

但得到了这个错误:

/usr/local/bin/../lib/node/wafadmin/Utils.py:136: DeprecationWarning: the md5 module is deprecated; use hashlib instead
from md5 import md5
Waf: Please run waf from a directory containing a file named "wscript" or run distclean
/usr/local/bin/../lib/node/wafadmin/Utils.py:136: DeprecationWarning: the md5 module is deprecated; use hashlib instead
from md5 import md5
arg[0] directory does not contain a wscript file

当我尝试构建orlandov/node-sqlite时,我从git中获取它,然后尝试:

node-waf configure build

但我得到这个错误:

我不能使用grumdrig/node-sqlite,因为它不支持异步访问.

谢谢你的任何建议.

Answer 1

当我的应用程序与我安装的一个软件包(npm)同名时,我收到此错误.我只是做了一些练习,并没想到我需要一个独特的项目名称......

只需将name您的内容更改package.json为其他内容即可.

Answer 2

你不需要执行

npm install sqlite3

在node-sqlite3文件夹中.通过执行此命令,您尝试安装sqlite3作为sqlite3的依赖项(您已经拥有它).

有两种方法可以安装sqlite3:

第一:

在你的项目文件夹中执行

npm install sqlite3

你不需要在它之前克隆git项目.不需要手动配置和制作.只需在要使用sqlite3模块的项目文件夹中执行此命令即可.在npm完成后,您应该在项目文件夹中看到文件夹node_modules/sqlite3.现在您可以通过require在项目中使用它:

var sqlite3 = require('sqlite3');

第二:

仅当npm安装失败时才使用此方法.(超自然).

1. 转到项目文件夹.
2. 如果不存在,则创建文件夹node_modules.

3. 执行:

   git clone git://github.com/developmentseed/node-sqlite3.git
   cd node-sqlite3
   ./configure
   make
   

4. 好.现在sqlite3半准备使用.我们需要安装依赖项.执行:

   npm install
   

   注意: npm install没有其他参数.此命令使用sqlite3文件夹中的package.json来安装依赖项.

在npm完成后,您可以在项目中使用sqlite3模块.

Answer 3

只需保留要安装的模块的目录,然后再次尝试安装.这对我有用.所以:

cd ..
npm install sqlite3
