NPM node_modules / .bin符号链接

我有一个NodeJS应用程序,在使用CI工具(Travis或CodeShip)后,在node_modules / .bin文件夹中遇到符号链接问题。

如果我跑......

  

npm install

在新的ubuntu服务器或我的开发机器上,我的node_modules / .bin文件夹如下所示:

lrwxrwxrwx 1 ubuntu ubuntu 19 May 10 14:35 gulp -> ../gulp/bin/gulp.js
lrwxrwxrwx 1 ubuntu ubuntu 25 May 10 14:35 nodemon -> ../nodemon/bin/nodemon.js
lrwxrwxrwx 1 ubuntu ubuntu 32 May 10 14:35 randomstring -> ../randomstring/bin/randomstring

但是,如果我通过TravisCI或CodeShip运行项目,则node_modules / .bin文件夹似乎已将符号链接展平,只剩下bin文件:

-rwxrwxr-x  1 ubuntu ubuntu 5384 Jan 31 20:55 gulp
-rwxrwxr-x  1 ubuntu ubuntu  441 Apr 29 20:31 nodemon
-rwxrwxr-x  1 ubuntu ubuntu  896 Feb 10 14:14 randomstring

问题是npm二进制文件无法解析它们自己的内部依赖项,因为bin没有在其npm模块文件夹的上下文中执行(例如node_modules / nodemon):

> nodemon app.js

module.js:327
    throw err;
    ^

因此,在尝试通过TravisCI / CodeShip部署后,我必须运行...

  

rm -R node_modules

     

npm install

运行任何npm脚本(例如npm start)。

是否有一个我不知道的配置项会让Travis / CodeShip变平/忽略符号链接?我已经研究了一段时间了,并找不到答案。

1 个答案:

答案 0 :(得分:0)

不幸的是,我还没能找到丢失的符号链接的明确答案。但是我通过添加以下内容解决了手头的问题:

npm install gulp

npm install nodemon

到修复符号链接的BeforeInstall部署挂钩。
