问题描述
我已经下载了lein，并将其放在我的/bin文件夹中，并使其可执行.我还下载了Java:
I've downloaded lein, put it in my /bin folder, and made it executable. I've also downloaded java:
$java -version
java version "1.7.0_65"
但是运行命令时出现以下错误:
But I get the following error upon running the command:
$lein

这是什么问题?预先谢谢你.
What is the problem here? Thank you in advance.
推荐答案
根据Alex的评论，该问题已通过替换格式错误的.lein/profiles.clj解决了:
As per Alex's comment, the problem was solved by replacing the malformed .lein/profiles.clj:
$nano .lein/profiles.clj
[lein-ancient "0.5.5"]
具有正确形成的轮廓.我使用了此配置文件，该文件位于gist.github.com/devn/4403577:
with a properly formed profile . I used this profile, found at gist.github.com/devn/4403577 :
{:user {:plugins [[lein-swank "1.4.5"]
;; [lein-pedantic "0.0.5"]
;; [lein-ritz "0.6.0"]
[lein-checkout-deps "1.0.0"]
;; [lein-haml-sass "0.2.4"]
[lein-midje "2.0.1"]
[lein-kibit "0.0.7"]]}
{:dependencies [[slamhound "1.3.0"]]}
{:aliases {"slamhound" ["run" "-m" "slam.hound"]}}}
