Building modules using node-gyp on Openshift
当尝试在 Openshift 上构建需要 node-gyp 之类的 node-canvas 的模块时,我收到此错误:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

我的理解是node-gyp正在导入找不到的gyp python模块。几周前,我通过将 PYTHONPATH env 变量设置为我的 node_modules 目录(/var/lib/…/repo/node_modules/node-gyp/gyp/pylib)中的那个 gyp python 模块解决了这个问题。这样构建就成功完成了,我可以使用 node-canvas 模块。现在我怀疑 Openshift 发生了一些变化,这种技术不再起作用了。即使设置了 PYTHONPATH,当我 npm install 模块时仍然找不到 gyp 模块。知道为什么即使 PYTHONPATH 设置为包含模块的位置也找不到 gyp 模块?也许它被忽略了? gyp 文件包含:
1 2 3 4 5 6 7 8 9 10 11 12

import sys
# TODO(mark): sys.path manipulation is some temporary testing stuff.
try:
import gyp
except ImportError, e:
import os.path
sys.path.append(os.path.join(os.path.dirname(sys.argv[0]), ‘pylib’))
import gyp
if __name__ == ‘__main__’:
sys.exit(gyp.main(sys.argv[1:]))

看不到不使用 PYTHONPATH 的原因(并且无法检查 gyp 文件中的 PYTHONPATH 值,因为它需要 root 权限,我认为我在 Openshift 上没有)。也许 npm 正在以某种方式重置环境?
- 现在在 node-gyp 中更改了 python 路径,因此您可以将以下内容添加到 pre_build 钩子中…… export PYTHONPATH=”${OPENSHIFT_REPO_DIR}node_modules/node-gyp/gyp”
我通过直接调用 node-gyp 而不是通过 npm install 来解决:
1 2 3

node-gyp configure
node-gyp build
node-gyp install

- 您是在 pre_build 钩子中运行它还是在 ssh 中作为 sudo 运行它?

锐库也有同样的问题。无法解决。我应该在服务器上的某个路径中运行”node-gyp configure”、”node-gyp build”、”node-gyp install”吗?
