ExecJS::ProgramError: 运行 rake 资产时出现意外的标记 punc «(»，预期的 punc «:»:在生产中预编译 [英] ExecJS::ProgramError: Unexpected token punc «(», expected punc «:» when running rake assets:precompile on production

问题描述

在部署我的 Rails 应用程序时出现以下错误:

rake 中止！ExecJS::ProgramError: Unexpected token punc «(», expected punc «:» (line: 15, col: 14, pos: 265)错误在新的 JS_Parse_Error (/tmp/execjs20150524-4411-1p45n63js:2359:10623)在 js_error (/tmp/execjs20150524-4411-1p45n63js:2359:10842)在 croak (/tmp/execjs20150524-4411-1p45n63js:2359:19086)在 token_error (/tmp/execjs20150524-4411-1p45n63js:2359:19223)在expect_token (/tmp/execjs20150524-4411-1p45n63js:2359:19446)在期望 (/tmp/execjs20150524-4411-1p45n63js:2359:19584)在/tmp/execjs20150524-4411-1p45n63js:2359:28513在/tmp/execjs20150524-4411-1p45n63js:2359:19957在 expr_atom (/tmp/execjs20150524-4411-1p45n63js:2359:27269)在maybe_unary (/tmp/execjs20150524-4411-1p45n63js:2359:30019)new JS_Parse_Error ((execjs):2359:10623)js_error ((execjs):2359:10842)呱呱 ((execjs):2359:19086)token_error ((execjs):2359:19223)expect_token ((execjs):2359:19446)期望((execjs):2359:19584)(execjs):2359:28513(execjs):2359:19957expr_atom ((execjs):2359:27269)may_unary ((execjs):2359:30019)

有问题的文件是有效的，它在本地主机上工作.我还尝试在本地主机上运行 rake assests:precompile，一切都通过了.最后，我尝试从文件中删除内容， git push 并重新部署 - 仍然遇到相同的错误.只有完全删除文件并重新部署才有帮助.

希望有任何想法.

解决方案

在这里，我找到了解决您遇到的相同问题的帮助.

一个>

运行 rails 控制台并:

JS_PATH = "app/assets/javascripts/**/*.js";Dir[JS_PATH].each do |file_name|puts "
#{file_name}"puts Uglifier.compile(File.read(file_name),harmony: true)结尾

它将显示文件和 Uglifier 导致问题的行.

When deploying my Rails app I get the following error:

rake aborted!

The file in question is valid, it works on localhost. I also tried running rake assests:precompile on localhost, it all passes. Finally, I tried to remove the content from the file, git push and redeploy - still got the same error. Only completely removing the file and re-deploying helps.

Would appreciate any ideas.

解决方案

Here I found help for the same problem you had.

Run rails console and:

JS_PATH = "app/assets/javascripts/**/*.js"; 
Dir[JS_PATH].each do |file_name|
  puts "
#{file_name}"
  puts Uglifier.compile(File.read(file_name), harmony: true)
end

It will show you the file and the line where the Uglifier is making the problem.
