sbt-java.io.FileNotFoundException

我sbt按照此说明进行安装入门 - 设置，在 Ubuntu 12.04 上。

当我运行时sbt，我看到下一个输出：

nazar_art@nazar-desctop:~$ sbt
java.io.FileNotFoundException: /home/nazar_art/.sbt/boot/update.log (No such file or directory)
    at java.io.FileOutputStream.open(Native Method)

    at xsbt.boot.Boot.main(Boot.scala)
Error during sbt execution: java.io.FileNotFoundException: /home/nazar_art/.sbt/boot/update.log (No such file or directory)
nazar_art@nazar-desctop:~$ sudo sbt
[sudo] password for nazar_art: 
Error occurred during initialization of VM
Could not reserve enough space for object heap

为了完全确认，我重复一下可执行脚本：

nazar_art@nazar-desctop:~$ chmod u+x ~/bin/sbt
nazar_art@nazar-desctop:~$ which sbt
/home/nazar_art/bin/sbt

更新：

update.log不存在。我创建于~/bin/.sbt/boot/update.log。

现在当我尝试运行时sbt我看到输出：

nazar_art@nazar-desctop:~/bin/.sbt/boot$ sbt
No command 'sbt' found, did you mean:
 Command 'skt' from package 'latex-sanskrit' (main)
 Command 'sb2' from package 'scratchbox2' (universe)
 Command 'sbd' from package 'cluster-glue' (main)
 Command 'mbt' from package 'mbt' (universe)
 Command 'sbmt' from package 'atfs' (universe)
 Command 'lbt' from package 'lbt' (universe)
 Command 'st' from package 'suckless-tools' (universe)
 Command 'sb' from package 'lrzsz' (universe)

更新：

update.log我准确移动了这个文件home/nazar_art/.sbt/boot 但是运行之后sbt我得到了相同的结果，但是Permission denied：

nazar_art@nazar-desctop:~/.sbt/boot$ pwd
/home/nazar_art/.sbt/boot
nazar_art@nazar-desctop:~/.sbt/boot$ ls 
update.log
nazar_art@nazar-desctop:~/.sbt/boot$ sbt

    at xsbt.boot.Boot.main(Boot.scala)

- 为什么会发生这种情况？
- 如何解决这个问题？

答案1

您应该检查以确保该文件~/.sbt/boot存在。如果不存在，那么您可能需要创建它。如果存在，请尝试touch ~/.sbt/boot/update.log以您的用户身份执行以创建该文件并根据需要设置其权限。
